Major Current Environmental Problems
1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels.
essential nutrients.
2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth’ surface causing melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation
3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources.
4. Natural Resource Depletion: Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy.
5. Waste Disposal: The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries.
6. Climate Change: Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming
7. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system
8. Deforestation: Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost
9. Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton in the same way as human osteoporosis.
10. Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s). Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer

Current Environmental Issues are÷
ReplyDelete1. Pollution:
Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.
2. Global Warming:
Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth’ surface causing melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation such as flash floods, excessive snow or desertification.
3. Overpopulation:
The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources. Intensive agriculture practiced to produce food damages the environment through use of chemical fertilizer, pesticides and insecticides. Overpopulation is one of the crucial current environmental problem.
4. Natural Resource Depletion:
Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy. The cost of installing the infrastructure and maintaining these sources has plummeted in the recent years.
5. Waste Disposal:
The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.
6. Climate Change:
Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, change in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario.
7. Loss of Biodiversity:
Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life.
8. Deforestation:
Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and make that land available for residential, industrial or commercial.

Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth. This is one of the most important current environmental problem
6.Acid Rain: Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain can be caused due to combustion of fossil fuels or erupting volcanoes or rotting vegetation which release sulfur dioxide and nitrogen oxides into the atmosphere. Acid rain is a known environmental problem that can have serious effect on human health, wildlife and aquatic species.
7.Public Health Issues: The current environmental problems pose a lot of risk to health of humans, and animals. Dirty water is the biggest health risk of the world and poses threat to the quality of life and public health. Run-off to rivers carries along toxins, chemicals and disease carrying organisms. Pollutants cause respiratory disease like Asthma and cardiac-vascular problems. High temperatures encourage the spread of infectious diseases like Dengue.

The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources. Intensive agriculture practiced to produce food damages the environment through use of chemical fertilizer, pesticides and insecticides. Overpopulation is one of the crucial current environmental problem.
4. Natural Resource Depletion:
Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy. The cost of installing the infrastructure and maintaining these sources has plummeted in the recent years.
5. Waste Disposal:
The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.
6. Climate Change:
Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, change in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario.
7. Loss of Biodiversity:
Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life.
8. Deforestation:
Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and make that land available for residential, industrial or commercial.

4.Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton in the same way as human osteoporosis.
5.Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s). Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer, the biggest of which is above the Antarctic. The CFC’s are banned in many industries and consumer products. Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth. This is one of the most important current environmental problem
6.Acid Rain: Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain can be caused due to combustion of fossil fuels or erupting volcanoes or rotting vegetation which release sulfur dioxide and nitrogen oxides into the atmosphere. Acid rain is a known environmental problem that can have serious effect on human health, wildlife and aquatic species.
7.Public Health Issues: The current environmental problems pose a lot of risk to health of humans, and animals. Dirty water is the biggest health risk of the world and poses threat to the quality of life and public health. Run-off to rivers carries along toxins, chemicals and disease carrying organisms. Pollutants cause respiratory disease like Asthma and cardiac-vascular problems. High temperatures encourage the spread of infectious diseases like Dengue.

Environmental Concerns
1. Air Pollution: Pollution of air, water and soil take a huge number of years to recover. Industry and engine vehicle fumes are the most obvious toxins. Substantial metals, nitrates and plastic are poisons in charge of pollution. While water contamination is brought about by oil slicks, acid rain, and urban sprawl; air contamination is created by different gasses and poisons discharged by businesses and manufacturing plants and burning of fossil fills; soil contamination is majorly created by mechanical waste that takes supplements out of the soil.
2. Water Pollution: Clean drinking water is turning into an uncommon thing. Water is turning into a monetary and political concern as the human populace battles for this need. Waste from industrial and agricultural activities pollute the water that is used by humans, animals and plants.
3: Soil and Land Pollution: Land pollution simply means degradation of earth’s surface as a result of human activities like mining, littering, deforestation, industrial, construction and agricultural activities. Land pollution can have huge environmental impact in the form of air pollution and soil pollution which in turn can have adverse effect on human health.
4. Climate Change: Climate change is yet another environmental concern that has surfaced in last couple of decades. Environmental change has different destructive impacts that include, but are not limited to, the melting of polar ice, change in seasons, new sicknesses, and change in general climate situation.
5. Global Warming: Environmental asset abuse is also an important environmental concern. Fossil fuel utilization brings about discharge of greenhouse gasses, which causes environmental change. However, individuals are taking endeavors to move to renewable energy sources.
6. Deforestation: Our woodlands create new oxygen and additionally help in managing temperature and precipitation. At present, timberlands cover 30% of the area, but wooded areas are being lost on a regular basis because people are looking for homes, food, and materials. Deforestation is a huge problem and will just continue to get worse.
7. Increased Carbon Footprint: Temperature increases, like climate change, are the consequence of human practices, including the use of greenhouse gasses. When the atmosphere changes and the heat increases, it can cause a number of problems and start to destroy the world we live in.
8. Genetic Modification: Genetic modification utilizing biotechnology is called genetic engineering. Genetic engineering of food brings about expanded poisons and sicknesses as qualities from a hypersensitive plant can exchange to target plant. Some of these crops can even be a threat to the world around us, as animals start to ingest the unnatural chemicals and such.
9. Effect on Marine Life: The amount of carbon in the water and the atmosphere is continuing to be a problem in the world around us. The primary effect is on shellfish and microscopic fish, and it has similar effects to osteoporosis in humans.

Some of the environmental issues are as follows:
ReplyDelete1. Contamination of Drinking Water
Contamination of fresh water used for household needs, including pollution of rivers, lakes, and reservoirs, ranks top on the list of environmental concerns for 61% of Americans. The Environmental Protection Agency (EPA) has set standards to ensure quality of drinking water to protect public health by limiting levels of various contaminants like microorganisms, disinfectants and their byproducts, inorganic compounds, organic compounds and radionuclides.
2. Water Pollution
General worry over water pollution and associated environmental issues greatly concerns more than half of all Americans who participated in the 2016 poll. Many water sources like streams, rivers and oceans are getting polluted. Related issues include acid rain, nutrient pollution, ocean dumping, urban runoff, oil spills, ocean acidification, and wastewater.
3. Air Pollution
Concerns over air pollution have remained steady over the last decade, with more than 40 percent of Americans worried about indoor and outdoor air quality, carbon emissions, and pollutants like particulate matter, sulfur oxides, volatile organic compounds, radon and refrigerants.
4. Wildlife Conservation and Species Extinction
More than 40 percent of Americans expressed concern about wildlife conservation and associated environmental issues, such as endangered species, animal and plant extinction, coral bleaching, introduction of invasive species, poaching, and loss of natural animal habitats.
5. Loss of Tropical Rainforests
Nearly 40% of Americans are worried about distant problems like loss of tropical forests. Rain forests cover only 2% of land but support 50% of its species according to Mongabay. Yet among tropical forests the area of rainforests cleared is the maximum, and most of it is export driven. "Every year an area of rainforest the size of New Jersey is cut down and destroyed,".
6.Energy conservation: Use of renewable energy for home and business, effecting energy efficiency, and avoiding fossil fuel use to mitigate climate change and protect the environment.
7. Biological pollutants: The EPA says that "biological contaminants are, or are produced by, living things." These include bacteria, viruses, molds, mildew, dander, dust, mites, and pollen, as indoor pollutants. They are found in places where there is food and moisture available. They can cause allergic reactions or infectious diseases, to which children and elderly people are more susceptible.
8. Carbon footprint: A carbon footprint is the amount of carbon emissions each person creates. Individuals can reduce this footprint and their effect on the environment, through use of renewable energy sources (solar power, geothermal heat pumps), recycling, and sustainable living.
9. Consumerism: Over-consumption affects the planet. Natural resources are finite and are being destroyed by current consumption patterns. A 2017 scientific study says global supply chains are threatening species in many biodiversity hotspots. Moreover 50-80% of resource use is dictated by household consumption, according to another 2015 study (pg. 1).
10. Dams and their impact on the environment: WWF reports there are 48,000 dams in the world, built to provide water for drinking and irrigation, and energy. However, they lead to habitat destruction, species loss, and displacing millions of people.

10. Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s).

1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number .While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.
2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth’ surface causing melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation such as flash floods, excessive snow or desertification.
3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources. Intensive agriculture practiced to produce food damages the environment through use of chemical fertilizer, pesticides and insecticides. Overpopulation is one of the crucial current environmental problem.
4. Natural Resource Depletion: Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy.
5. Waste Disposal: The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.
6. Climate Change: Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, change in seasons, occurrence of new diseases, frequent occurrence of floods
7. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system and human activity threatens the same.
8. Deforestation: Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food,
9. Ocean Acidification: It is a direct impact of excessive production The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton in the same way as human osteoporosis.
10. Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays.Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer, the biggest of which is above the Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth

Waste Disposal: The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.
Climate Change: Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, change in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario.
1. Air pollution and climate change.
ReplyDeleteProblem: Overloading of the atmosphere and of ocean waters with carbon. Atmospheric CO2 absorbs and re-emits infrared-wavelength radiation, leading to warmer air, soils, and ocean surface waters - which is good: The planet would be frozen solid without this.
Unfortunately, there's now too much carbon in the air. Burning of fossil fuels, deforestation for agriculture, and industrial activities have pushed up atmospheric CO2 concentrations from 280 parts per million (ppm) 200 years ago, to about 400 ppm today. That's an unprecedented rise, in both size and speed. The result: climate disruption.
Carbon overloading is only one form of air pollution caused by burning coal, oil, gas and wood. The World Health Organization recently estimated that one in nine deaths in 2012 were attributable to diseases caused by carcinogens and other poisons in polluted air.
Ocean life is suffering a triple whammy: overfishing, pollution and warming waters due to climate change
Solutions: Replace fossil fuels with renewable energy. Reforestation. Reduce emissions from agriculture. Change industrial processes.
The good news is that clean energy is abundant - it just needs to be harvested. Many say a 100 percent renewable-energy future is feasible with existing technology now.
But the bad news is that even though renewable energy infrastructure - solar panels, wind turbines, energy storage and distribution systems - are already widespread, and getting cheaper and more efficient all the time, experts say we're not applying them quickly enough to prevent catastrophic climate disruption. Barriers in policy and finance remain to be overcome.
2. Deforestation.
Problem: Species-rich wild forests are being destroyed, especially in the tropics, often to make way for cattle ranching, soybean or palm oil plantations, or other agricultural monocultures.
Destruction of forests has impacts for biodiversity and the climate
Today, about 30 percent of the planet's land area is covered by forests - which is about half as much as before agriculture got started around 11,000 years ago. About 7.3 million hectares (18 million acres) of forest are destroyed each year, mostly in the tropics. Tropical forests used to cover about 15 percent of the planet's land area; they're now down to 6 or 7 percent. Much of this remainder has been degraded by logging or burning.
Not only do natural forests act as biodiversity reserves, they are also carbon sinks, keeping carbon out of the atmosphere and oceans.
Solutions: Conserve of what's left of natural forests, and restore degraded areas by replanting with native tree species. This requires strong governance - but many tropical countries are still developing, with increasing populations, uneven rule-of-law, and widespread cronyism and bribery when it comes to allocating land use.
3. Species extinction.
Problem: On land, wild animals are being hunted to extinction for bushmeat, ivory, or "medicinal" products. At sea, huge industrial fishing boats equipped with bottom-trawling or purse-seine nets clean out entire fish populations. The loss and destruction of habitat are also major factors contributing to a wave of extinction - unprecedented in that it is caused by a single species: humans. The IUCN's Red List of threatened and endangered species continues to grow.
Rhinos are killed for their horn, which some people falsely believe has medicinal properties
Not only do species inherently deserve to exist, they also provide products and "services" essential to human survival. Think bees and their pollinating prowess - necessary for growing food.
Solutions: Concerted efforts need to be made to prevent further loss of biodiversity. Protecting and restoring habitats is one side of this - protecting against poaching and wildlife trade is another. This should be done in partnership with locals, so that wildlife conservation is in their social and economic interest.

1.1. Pollution: More than half of the human population knows what is pollution, but we are still not ready to face its damaging consequences. Pollution is not only limited to water, soil and noise but has extended to light, visual, point and non-point sources. Human beings and their actions are majorly responsible for causing all types of pollution. Water pollution is essentially cause by oil spills, urban runoff and ocean dumping. Air pollution rises from burning of fossil fuels, hydraulic fracturing and gases emitted by vehicles. Water and soil pollution are majorly cause from industrial waste.
ReplyDelete2. Climate Change: Climate change today is less of a natural process. It is rapidly occurring due to the ill effects of human actions responsible for disturbing and harmful out comings such as global warming, greenhouse effect, urban heat, coal industry etc. Climate change is not only changing the overall weather scenario, but has larger and harmful effects. Some of these include: melting of polar regions, occurrence of new diseases and permanent inhibition in growth of certain plants essential for human survival.
3. Global Warming: Global warming is another environmental issue which is increase in earth’s temperature due to effect of greenhouse gases called carbon dioxide, methane, water vapor and other gases. These gases possess heat trapping capacity that are needed to create greenhouse effect so that this planet remains warm for people to survive. Without these gases, this planet would turn be cold for life to exist. During past several decades, the accumulation of greenhouse gases have grown rapidly, which means more heat gets trapped in the atmosphere and few of these gases escapes back into the space. These gases heat up the earth’s surface and this results in global warming. . Global warming can have long lasting effects which can result in melting of glaciers, climate change, droughts, diseases and increase in hurricanes frequency. 4. Deforestation: With population growing at a rapid pace, the demand for food, shelter and cloth has almost tripled in last few decades. To overcome growing demand, a direct action that we have come to recognize as “Deforestation” occurs. Deforestation means, clearing of forests or green cover for means of agriculture, industrial or urban use. It involves permanent end of forest cover to make that land available for residential, commercial or industrial purpose. The long term effects of deforestation can be severely devastating and alarming as they may cause floods, soil erosion, increase in global warming, climate imbalance, wildlife extinction and other serious environmental issues. 5. Overpopulation: This is a never-ending human tragedy which is responsible for causing all types of environmental issues. Water pollution, resources crisis, gender imbalance, pollution, land pollution, urban sprawling, deforestation, over production are some common examples of dangerous effects cause by overpopulation.
6. Acid Rain: Acid rain simply means rain that is acidic in nature due to the presence of certain pollutants in the atmosphere. These pollutants come in the atmosphere due to car or industrial processes. Acid rain can occur in form of rain, snow, fog or dry material that settle to earth. Acid rain may cause due to erupting volcanoes, rotting vegetation and sea sprays that produce sulfur dioxide and fires, bacterial decomposition and lightening generate nitrogen dioxide.

10 Major Environmental Challenges Faced by India
1. Growing Population:
A population of over thousands of millions is growing at 2.11 per cent every year. It puts considerable pressure on its natural resources and reduces the gains of development. Hence, the greatest challenge before us is to limit the population growth. Although population control does automatically lead to development, yet the development leads to a decrease in population growth rates.
2. Poverty:
India has often been described a rich land with poor people. The poverty and environmental degradation have a nexus between them. The vast majority of our people are directly dependent on the nature resources of the country for their basic needs of food, fuel shelter and fodder. About 40% of our people are still below the poverty line.
Environment degradation has adversely affected the poor who depend upon the resources of their immediate surroundings. Thus, the challenge of poverty and the challenge environment degradation are two facts of the same challenge. The population growth is essentially a function of poverty. Because, to the very poor, every child is an earner and helper and global concerns have little relevance for him.
3. Agricultural Growth:
The people must be acquainted with the methods to sustain and increase agricultural growth with damaging the environment. High yielding varieties have caused soil salinity and damage to physical structure of soil.
4. Need to Ground Water:
It is essential of rationalizing the use of groundwater. Factors like community wastes, industrial effluents and chemical fertilizers and pesticides have polluted our surface water and affected quality of the groundwater.
It is essential to restore the water quality of our rivers and other water body as lakes is an important challenge. It so finding our suitable strategies for consecration of water, provision of safe drinking water and keeping water bodies clean which are difficult challenges is essential.
5. Development and Forests:
Forests serve catchments for the rivers. With increasing demand of water, plan to harness the mighty river through large irrigation projects were made. Certainly, these would submerge forests; displace local people, damage flora and fauna.
As such, the dams on the river Narmada, Bhagirathi and elsewhere have become areas of political and scientific debate. Forests in India have been shrinking for several centuries owing to pressures of agriculture and other uses. Vast areas that were once green, stand today as wastelands.
These areas are to be brought back under vegetative cover. The tribal communities inhabiting forests respects the trees and birds and animal that gives them sustenance. We must recognize the role of these people in restoring and conserving forests.
The modern knowledge and skills of the forest dept. should be integrated with the traditional knowledge and experience of the local communities. The strategies for the joint management of forests should be evolved in a well planned way.

6. Degradation of Land:
At present out of the total 329 mha of land, only 266 mha possess any potential for production. Of this, 143 mha is agricultural land nearly and 85 suffer from varying degrees of soil degradation. Of the remaining 123 mha, 40 are completely unproductive.
The remaining 83 mha is classified as forest land, of which over half is denuded to various degrees. Nearly 406 million head of livestock have to be supported on 13 mha, or less than 4 per cent of the land classified as pasture land, most of which is overgrazed. Thus, our of 226 mha, about 175 mha or 66 per cent is degraded to varying degrees. Water and wind erosion causes further degradation of almost 150 mha.
7. Reorientation of Institutions:
The people should be roused to orient institutions, attitudes and infrastructures, to suit conditions and needs today. The change has to be brought in keeping in view India’s traditions for resources use managements and education etc. Change should be brought in education, in attitudes, in administrative procedures and in institutions. Because it affects way people view technology resources and development.
8. Reduction of Genetic Diversity:
At present most wild genetic stocks have been disappearing from nature. Wilding including the Asiatic Lion are facing problem of loss of genetic diversity. The protected areas network like sanctuaries, national parks, biosphere reserves are isolating populations. So, they are decreasing changes of one group breeding with another. Remedial steps are to be taken to check decreasing genetic diversity.
9. Evil Consequences of Urbanization:
Nearly 27 per cent Indians live in urban areas. Urbanization and industrialization has given birth to a great number of environmental problems that need urgent attention. Over 30 per cent of urban Indians live in slums. Out of India’s 3,245 towns and cities, only 21 have partial or full sewerage and treatment facilities. Hence, coping with rapid urbanization is a major challenge.
10. Air and Water Population:
Majority of our industrial plants are using out-dated and population technologies and makeshift facilities devoid of any provision of treating their wastes. A great number of cities and industrial areas that have been identified as the worst in terms of air and water pollution.
Acts are enforced in the country, but their implement is not so easy. The reason is their implementation needs great resources, technical expertise, political and social will. Again the people are to be made aware of these rules. Their support is indispensable to implement these rules

Current Environmental Issues are÷
ReplyDelete1. Pollution:
Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.
2. Population
Due to increase in population,in family members increases the environmental issues which is very badly harmful for our life i.e. Through increase in population leads to all kinds of pollution ,wastage , different thoughts brings different ideas and brings affect in environment , increase in ideas leads to innovation and through that there is a creation of industries etc.
3. Overpopulation:
The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources. Intensive agriculture practiced to produce food damages the environment through use of chemical fertilizer, pesticides and insecticides.

Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life.
8. Deforestation:
Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and make that land available for residential, industrial or commercial.

1. The Hemorrhaging of Biodiversity: Our species’ activity within the last century is responsible for rapidly diminishing the diversity of life forms on this planet. Each species lost is a storehouse of environmental knowledge selected for over millions of years.
2. Degrading the Ozone Layer: Certain industrial compounds, such as organohalogens, break down ozone in the stratosphere at very high rates for long periods of time and greatly reduce the ozone’s ability to protect surface life from UV radiation.
3. Changing Climates: Humanity has released sufficient quantities of greenhouse gases into the atmosphere over the last century that we are now starting to feel the effects of an inevitably warmer world.
4. Toxins: Radioactive materials, pesticides, herbicides, fungicides, nematocides―all of these man-made products kill or harm life.
5. Dying Oceans: Overfishing has decimated most fisheries and the oceans are now devoid of over 95% of its larger predatory fish. Coral reefs are degrading almost everywhere they occur due to warming and acidifying seas, overfishing, and sediment- and toxin-laden runoff from the land. And the tons and tons of discarded plastic that ends up in the ocean kills and sickens marine life up and down the food chain.

IMPORTANT ENVIRONMENTAL PROBLEMS
1. CLIMATE CHANGE
Global warming has been concerning scientists for decades, but Al Gore legitimized the crisis with his controversial film An Inconvenient Truth. From the melting polar ice caps to catastrophic weather and threatened ecosystems, not only is climate change real, scientists agree that humans are influencing climate change with our production of greenhouse gases (mainly stemming from carbon dioxide and methane). What can you do? How bad is it? Why do so many people still think climate change isn’t real? Is it real? These are just some of the issues worth exploring. The good news is that despite the urgency of the crisis, there are exciting technological developments as well as meaningful lifestyle changes you can make to help.
2. ENERGY
Clean energy vs. dirty energy. Renewable energy. Energy independence. Petroleum. Biofuels. Coal. ANWR and offshore drilling. Even Paris Hilton has something to say about energy. Energy is second only to climate change in significance, but the picture isn't as clear as one might think. China is heavily criticized, but did you know the state of California is worse? Look for plenty of myth-busting and interesting news to come, as well as practical tips to reduce your own energy dependence. Though no single energy source is going to be the solution, positive developments toward a cleaner future are happening every single day.
3. WASTE
With the immediate looming problems of climate change and energy, focus has shifted away from landfill waste, but this is a serious problem. The world has largely gotten accustomed to a throwaway lifestyle, but that’s neither healthy nor sustainable. Waterways are choked with trash and modernized nations ship their undesirable leftovers to the developing world. Fashion fashion, fast food, packaging and cheap electronics are just some of the problems. The amount of waste the industrialized world generates is shocking. Water bottles are the defining symbol of this critical issue. Fortunately, people are becoming aware of the consequences of "fast consumption" and there are many simple changes you can make in your own life to help significantly reduce landfill waste.
4. WATER
Pure Water is in short supply. Our global reserves of drinkable water are a fraction of 1% and 1 in 5 humans does not have access to potable (safe) water. Many people do not realize that strife has already broken out in some stressed regions. There are many potential solutions, some promising, others challenging. Desalinization is an energy-inefficient, expensive option. But there are many things you can do. (Hint: it starts with turning off the faucet when you brush.)
5. FOOD
Biofuels have turned into a global controversy – the idea that people may causing the starvation of millions in order to fuel their SUVs is sickening. And yet that’s not the whole picture. For example, eating hamburgers has as much or more impact on the global food picture as the use of biofuels. And then there’s the whole issue of “food miles” – at first, local seemed logical, but the situation is more complex than that. It’s all about resources and efficiency. There are big questions: can we support the world without turning to vegetarianism? We know that the planet can’t afford the Western way of eating. It would take 5 earths to support that lifestyle! What about hunting – is that good for the environment? Look for more articles soon exploring the complicated world of food. Fortunately, there are a multitude of tasty diets that incorporate greener values, so it's not necessary to adhere to veganism, for example.

1. Public Health Issues: The current environmental problems pose a lot of risk to health of humans, and animals. Dirty water is the biggest health risk of the world and poses threat to the quality of life and public health.
2. Urban Sprawl: Urban sprawl refers to migration of population from high density urban areas to low density rural areas which results in spreading of city over more and more rural land. Urban sprawl results in land degradation, increased traffic, environmental issues and health issues.
3. Water Pollution: Clean drinking water is becoming a rare commodity. Water is becoming an economic and political issue as the human population fights for this resource.
4. Acid Rain: Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain can be caused due to combustion of fossil fuels or erupting volcanoes or rotting vegetation which release sulfur dioxide and nitrogen oxides into the atmosphere.
5. Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s).
6. Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans.
7. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating.
8. Climate Change: Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries.
9. Waste Disposal: The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries.
10. Natural Resource Depletion: Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change.

Current Environmental Issues are÷
ReplyDelete1. Pollution:
Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.
2. Global Warming:
Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth’ surface causing melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation such as flash floods, excessive snow or desertification.
3. Overpopulation:
The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources. Intensive agriculture practiced to produce food damages the environment through use of chemical fertilizer, pesticides and insecticides. Overpopulation is one of the crucial current environmental problem.
4. Natural Resource Depletion:
Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy. The cost of installing the infrastructure and maintaining these sources has plummeted in the recent years.
5. Waste Disposal:
The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.
6. Climate Change:
Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, change in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario.
7. Loss of Biodiversity:
Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life.
8. Deforestation:
Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and make that land available for residential, industrial or commercial.

Climate Change
From the melting polar ice caps to catastrophic weather and threatened ecosystems, not only is climate change real, scientists agree that humans are influencing climate change with our production of greenhouse gases (mainly stemming from carbon dioxide and methane).The good news is that despite the urgency of the crisis, there are exciting technological developments as well as meaningful lifestyle changes you can make to help.
2. Energy
Clean energy vs. dirty energy. Renewable energy. Energy independence. Petroleum. Biofuels. Coal. ANWR and offshore drilling. Energy is second only to climate change in significance, but the picture isn't as clear as one might think. China is heavily criticized, but did you know the state of California is worse?
3. Waste
With the immediate looming problems of climate change and energy, focus has shifted away from landfill waste, but this is a serious problem. The world has largely gotten accustomed to a throwaway lifestyle, but that’s neither healthy nor sustainable. Waterways are choked with trash and modernized nations ship their undesirable leftovers to the developing world.The amount of waste the industrialized world generates is shocking. Water bottles are the defining symbol of this critical issue. Fortunately, people are becoming aware of the consequences of "fast consumption".
4. Water
Pure Water is in short supply. Our global reserves of drinkable water are a fraction of 1% and 1 in 5 humans does not have access to potable (safe) water. Many people do not realize that strife has already broken out in some stressed regions. There are many potential solutions, some promising, others challenging. Desalinization is an energy-inefficient, expensive option.
5. Food
Biofuels have turned into a global controversy – the idea that people may causing the starvation of millions in order to fuel their SUVs is sickening. And yet that’s not the whole picture. For example, eating hamburgers has as much or more impact on the global food picture as the use of biofuels. And then there’s the whole issue of “food miles” – at first, local seemed logical, but the situation is more complex than that. It’s all about resources and efficiency.
6. Consumption
This is directly tied to waste. It is well-known that the industrialized world simply consumes in a way that is not sustainable. And the developing world is rapidly imitating the model. Sustainability in the most compelling sense is about long-term solvency. Reducing consumption, and smart consumption, are both necessary – and there are many ways to go about doing this.
7. Land Management
From desertification to polar ice melting to erosion and deforestation, existing land management choices are not serving the planet or its inhabitants very well. There is very little land left that is undeveloped, either with structures or roads. And there is virtually no land left that is not subject to light or noise pollution. The modern green movement believes that in order to create a sustainable future, people will need to return to the conservation spirit.
8. Ecosystems and Endangered Species
The good news is that some species have made a comeback. The bad news is that many more species are now under threat, including indicator species and evolutionarily unique species.The consequences can have global impact.

7.Public Health Issues: The current environmental problems pose a lot of risk to health of humans, and animals. Dirty water is the biggest health risk of the world and poses threat to the quality of life and public health. Run-off to rivers carries along toxins, chemicals and disease carrying organisms. Pollutants cause respiratory disease like Asthma and cardiac-vascular problems. High temperatures encourage the spread of infectious diseases like Dengue.

Global Warming: Global warming is another environmental issue which is increase in earth’s temperature due to effect of greenhouse gases called carbon dioxide, methane, water vapor and other gases. These gases possess heat trapping capacity that are needed to create greenhouse effect so that this planet remains warm for people to survive. Without these gases, this planet would turn be cold for life to exist.
During past several decades, the accumulation of greenhouse gases have grown rapidly, which means more heat gets trapped in the atmosphere and few of these gases escapes back into the space. These gases heat up the earth’s surface and this results in global warming. According to Environmental Protection Agency (EPA) reports, the earth’s temperature has increased by 0.8 degrees Celsius over the past century. Global warming is a serious public health and environmental concern. Global warming can have long lasting effects which can result in melting of glaciers, climate change, droughts, diseases and increase in hurricanes frequency.

9. Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton in the same way as human osteoporosis.
10. Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s). Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth. This is one of the most important current environmental problem
Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste that deprives soil from essential nutrients.
ReplyDelete2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth’ surface causing melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation such as flash floods, excessive snow or desertification.
3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources. Intensive agriculture practiced to produce food damages the environment through use of chemical fertilizer, pesticides and insecticides. Overpopulation is one of the crucial current environmental problem.
4. Natural Resource Depletion: Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy. The cost of installing the infrastructure and maintaining these sources has plummeted in the recent years.
5. Waste Disposal: The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.
6. Climate Change: Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, change in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario.
7. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life.
8. Deforestation: Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and make that land available for residential, industrial or commercial purpose

Pollution: More than half of the human population knows what is pollution, but we are still not ready to face its damaging consequences. Pollution is not only limited to water, soil and noise but has extended to light, visual, point and non-point sources. Human beings and their actions are majorly responsible for causing all types of pollution. Water pollution is essentially cause by oil spills, urban runoff and ocean dumping. Air pollution rises from burning of fossil fuels, hydraulic fracturing and gases emitted by vehicles. Water and soil pollution are majorly cause from industrial waste.
ReplyDelete2. Climate Change: Climate change today is less of a natural process. It is rapidly occurring due to the ill effects of human actions responsible for disturbing and harmful out comings such as global warming, greenhouse effect, urban heat, coal industry etc. Climate change is not only changing the overall weather scenario, but has larger and harmful effects. Some of these include: melting of polar regions, occurrence of new diseases and permanent inhibition in growth of certain plants essential for human survival.
3. Global Warming: Global warming is another environmental issue which is increase in earth’s temperature due to effect of greenhouse gases called carbon dioxide, methane, water vapor and other gases. These gases possess heat trapping capacity that are needed to create greenhouse effect so that this planet remains warm for people to survive. Without these gases, this planet would turn be cold for life to exist.
During past several decades, the accumulation of greenhouse gases have grown rapidly, which means more heat gets trapped in the atmosphere and few of these gases escapes back into the space. These gases heat up the earth’s surface and this results in global warming. According to Environmental Protection Agency (EPA) reports, the earth’s temperature has increased by 0.8 degrees Celsius over the past century. Global warming is a serious public health and environmental concern. Global warming can have long lasting effects which can result in melting of glaciers, climate change, droughts, diseases and increase in hurricanes frequency.
4. Deforestation: With population growing at a rapid pace, the demand for food, shelter and cloth has almost tripled in last few decades. To overcome growing demand, a direct action that we have come to recognize as “Deforestation” occurs. Deforestation means, clearing of forests or green cover for means of agriculture, industrial or urban use. It involves permanent end of forest cover to make that land available for residential, commercial or industrial purpose.
According to the United Nations Food and Agriculture Organization (FAO), an estimated 18 million acres (7.3 million hectares) of forest are lost each year. The long term effects of deforestation can be severely devastating and alarming as they may cause floods, soil erosion, increase in global warming, climate imbalance, wildlife extinction and other serious environmental issues.
5. Overpopulation: This is a never-ending human tragedy which is responsible for causing all types of environmental issues. Water pollution, resources crisis, gender imbalance, pollution, land pollution, urban sprawling, deforestation, over production are some common examples of dangerous effects cause by overpopulation. Despite efforts taken by the government in terms of family planning in many countries, over population is difficult to control at international level. This has become more like a subjective concern and no method seems to be 100% efficient to resolve the problem of over population.

Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer, the biggest of which is above the Antarctic. The CFC’s are banned in many industries and consumer products. Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth. This is one of the most important current environmental problem.
waste management: Waste management is collection, transportation, and disposal of garbage, sewage and other waste products. Waste management is the process of treating solid wastes and offers variety of solutions for recycling items that don't belong to trash. It is about how garbage can be used as a valuable resource.
ReplyDeleteAir pollution: The condition in which air is contaminated by foreign substances, or the substances themselves.
Air pollution consists of gaseous, liquid, or solid substances that, when present in sufficient concentration, for a sufficient time, and under certain conditions, tend to interfere with human comfort, health or welfare, and cause environmental damage. Air pollution causes acid rain, ozone depletion, photochemical smog, and other such phenomena.

Major environmental issues are forest and agricultural degradation of land, resource depletion (such as water, mineral, forest, sand, and rocks), environmental degradation, public health, loss of biodiversity, loss of resilience in ecosystems, livelihood security for the poor.
The major sources of pollution in India include the rapid burning of fuelwood and biomass such as dried waste from livestock as the primary source of energy, lack of organised garbage and waste removal services, lack of sewage treatment operations
Air pollution, poor management of waste, growing water scarcity, falling groundwater tables, water pollution, preservation and quality of forests, biodiversity loss, and land/soil degradation are some of the major environmental issues India faces today.
India's population growth adds pressure to environmental issues and its resources. Rapid urbanization has caused a buildup of heavy metals in the soil of the city of Ghaziabad, and these metals are being ingested through contaminated vegetables. Heavy metals are hazardous to people's health and are known carcinogens.
Water pollution:India has major water pollution issues. Discharge of untreated sewage is the single most important cause for pollution of surface and ground water in India. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.
Air Pollution:Air pollution in India is a serious issue with the major sources being fuelwood and biomass burning, fuel adulteration, vehicle emission and traffic congestion. Air pollution is also the main cause of the Asian brown cloud, which is causing the monsoon to be delayed. India is the world's largest consumer of fuelwood, agricultural waste and biomass for energy purposes. Traditional fuel (fuelwood, crop residue and dung cake) dominates domestic energy use in rural India and accounts for about 90% of the total. In urban areas, this traditional fuel constitutes about 24% of the total.ss-based household stoves in India are also a leading source of greenhouse emissions contributing to climate change.
Noise pollution:Noise pollution or noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life. Noise-wise India can be termed as the most polluted country in the world.The source of most outdoor noise worldwide is mainly caused by machines and transportation systems, motor vehicles, aircraft, and trains.In India the outdoor noise is also caused by loud music during festival seasons.Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential areas.
Indoor noise can be caused by machines, building activities, and music performances, especially in some workplaces. Noise-induced hearing loss can be caused by outside (e.g. trains) or inside (e.g. music) noise.
High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease.In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.
Land pollution:In March 2009, the issue of Uranium poisoning in Punjab attracted press coverage.The news reports claimed the uranium levels were more than 60 times the maximum safe limit.In 2012, the Government of India confirmed[48] that the ground water in Malwa belt of Punjab has uranium metal that is 50% above the trace limits set by the United Nations' World Health Organization. Scientific studies, based on over 1000 samples from various sampling points, could not trace the source to fly ash and any sources from thermal power plants or industry as originally alleged.

Types & Causes of Pollution
Air Pollution is the most prominent and dangerous form of pollution. It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air everyday; these pollute the air.
Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic. The effects of air pollution are evident too. Release of sulphur dioxide and hazardous gases into the air causes global warming and acid rain; which in turn have increased temperatures, erratic rains and droughts worldwide; making it tough for the animals to survive. We breathe in every polluted particle from the air; result is increase in asthma and cancer in the lungs.
Water Pollution has taken toll of all the surviving species of the earth. Almost 60% of the species live in water bodies. It occurs due to several factors; the industrial wastes dumped into the rivers and other water bodies cause an imbalance in the water leading to its severe contamination and death of aquatic species. If you suspect that nearby water sources have been contaminated by a corporation then it might be a good idea to hire an expert to see your options.
Also spraying insecticides, pesticides like DDT on plants pollutes the ground water system and oil spills in the oceans have caused irreparable damage to the water bodies. Eutrophication is another big source; it occurs due to daily activities like washing clothes, utensils near lakes, ponds or rivers; this forces detergents to go into water which blocks sunlight from penetrating, thus reducing oxygen and making it inhabitable.
Water pollution not only harms the aquatic beings but it also contaminates the entire food chain by severely affecting humans dependent on these. Water-borne diseases like cholera, diarrhoea have also increased in all places.
Soil pollution occurs due to incorporation of unwanted chemicals in the soil due to human activities. Use of insecticides and pesticides absorbs the nitrogen compounds from the soil making it unfit for plants to derive nutrition from. Release of industrial waste, mining and deforestation also exploits the soil. Since plants can’t grow properly, they can’t hold the soil and this leads to soil erosion.
Noise pollution is caused when noise which is an unpleasant sound affects our ears and leads to psychological problems like stress, hypertension, hearing impairment, etc. It is caused by machines in industries, loud music, etc.
Radioactive pollution is highly dangerous when it occurs. It can occur due to nuclear plant malfunctions, improper nuclear waste disposal, accidents, etc. It causes cancer, infertility, blindness, defects at the time of birth; can sterilise soil and affect air and water.
Thermal/heat pollution is due to the excess heat in the environment creating unwanted changes over long time periods; due to huge number of industrial plants, deforestation and air pollution. It increases the earth’s temperature, causing drastic climatic changes and extinction of wildlife.
Light pollution occurs due to prominent excess illumination of an area. It is largely visible in big cities, on advertising boards and billboards, in sports or entertainment events at the night. In residential areas the lives of the inhabitants is greatly affected by this. It also affects the astronomical observations and activities by making the stars almost invisible.

Types & Causes of Pollution
Air Pollution is the most prominent and dangerous form of pollution. It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air everyday; these pollute the air.
Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic. The effects of air pollution are evident too. Release of sulphur dioxide and hazardous gases into the air causes global warming and acid rain; which in turn have increased temperatures, erratic rains and droughts worldwide; making it tough for the animals to survive. We breathe in every polluted particle from the air; result is increase in asthma and cancer in the lungs.
Water Pollution has taken toll of all the surviving species of the earth. Almost 60% of the species live in water bodies. It occurs due to several factors; the industrial wastes dumped into the rivers and other water bodies cause an imbalance in the water leading to its severe contamination and death of aquatic species. If you suspect that nearby water sources have been contaminated by a corporation then it might be a good idea to hire an expert to see your options.
Also spraying insecticides, pesticides like DDT on plants pollutes the ground water system and oil spills in the oceans have caused irreparable damage to the water bodies. Eutrophication is another big source; it occurs due to daily activities like washing clothes, utensils near lakes, ponds or rivers; this forces detergents to go into water which blocks sunlight from penetrating, thus reducing oxygen and making it inhabitable.
Water pollution not only harms the aquatic beings but it also contaminates the entire food chain by severely affecting humans dependent on these. Water-borne diseases like cholera, diarrhoea have also increased in all places.
Soil pollution occurs due to incorporation of unwanted chemicals in the soil due to human activities. Use of insecticides and pesticides absorbs the nitrogen compounds from the soil making it unfit for plants to derive nutrition from. Release of industrial waste, mining and deforestation also exploits the soil. Since plants can’t grow properly, they can’t hold the soil and this leads to soil erosion.
Noise pollution is caused when noise which is an unpleasant sound affects our ears and leads to psychological problems like stress, hypertension, hearing impairment, etc. It is caused by machines in industries, loud music, etc.
Radioactive pollution is highly dangerous when it occurs. It can occur due to nuclear plant malfunctions, improper nuclear waste disposal, accidents, etc. It causes cancer, infertility, blindness, defects at the time of birth; can sterilise soil and affect air and water.
Thermal/heat pollution is due to the excess heat in the environment creating unwanted changes over long time periods; due to huge number of industrial plants, deforestation and air pollution. It increases the earth’s temperature, causing drastic climatic changes and extinction of wildlife.
Light pollution occurs due to prominent excess illumination of an area. It is largely visible in big cities, on advertising boards and billboards, in sports or entertainment events at the night.

Environmental issues are:-
1.) Air pollution:- Air is the source for our life and the life of other living beings. This air we breath is pure but not as it was before now days this air is being polluted by wrong developmental technology.
Over population:- Humans as a man power is great power for country but not on the cost of their decreased life span and quality. People who can afford the care of each children can have them but the people who can't and are not willing to care diligently for their children must not plan more kids. Children are always the gifts from God but we must know the value of God's gifts which are in the form of children to us.
Poverty:- Poor people are not poor from money but are poor from God's kingdom and his righteousness. If they really seek first the kingdom of God and his Righteousness they wil be richest of this globe.

Major environmental issues are forest and agricultural degradation of land, resource depletion (such as water, mineral, forest, sand, and rocks), environmental degradation, public health, loss of biodiversity, loss of resilience in ecosystems, livelihood security for the poor.
The major sources of pollution in India include the rapid burning of fuelwood and biomass such as dried waste from livestock as the primary source of energy, lack of organised garbage and waste removal services, lack of sewage treatment operations
Air pollution, poor management of waste, growing water scarcity, falling groundwater tables, water pollution, preservation and quality of forests, biodiversity loss, and land/soil degradation are some of the major environmental issues India faces today.
India's population growth adds pressure to environmental issues and its resources. Rapid urbanization has caused a buildup of heavy metals in the soil of the city of Ghaziabad, and these metals are being ingested through contaminated vegetables. Heavy metals are hazardous to people's health and are known carcinogens.
Water pollution:India has major water pollution issues. Discharge of untreated sewage is the single most important cause for pollution of surface and ground water in India. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.
Air Pollution:Air pollution in India is a serious issue with the major sources being fuelwood and biomass burning, fuel adulteration, vehicle emission and traffic congestion. Air pollution is also the main cause of the Asian brown cloud, which is causing the monsoon to be delayed. India is the world's largest consumer of fuelwood, agricultural waste and biomass for energy purposes. Traditional fuel (fuelwood, crop residue and dung cake) dominates domestic energy use in rural India and accounts for about 90% of the total. In urban areas, this traditional fuel constitutes about 24% of the total.ss-based household stoves in India are also a leading source of greenhouse emissions contributing to climate change.
Noise pollution:Noise pollution or noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life. Noise-wise India can be termed as the most polluted country in the world.The source of most outdoor noise worldwide is mainly caused by machines and transportation systems, motor vehicles, aircraft, and trains.In India the outdoor noise is also caused by loud music during festival seasons.Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential areas.
Indoor noise can be caused by machines, building activities, and music performances, especially in some workplaces. Noise-induced hearing loss can be caused by outside (e.g. trains) or inside (e.g. music) noise.
High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease.In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.
Land pollution:In March 2009, the issue of Uranium poisoning in Punjab attracted press coverage.The news reports claimed the uranium levels were more than 60 times the maximum safe limit.In 2012, the Government of India confirmed[48] that the ground water in Malwa belt of Punjab has uranium metal that is 50% above the trace limits set by the United Nations' World Health Organization. Scientific studies, based on over 1000 samples from various sampling points, could not trace the source to fly ash and any sources from thermal power plants or industry as originally alleged

Pollution: Pollution of air, water and soil require millions of years to recoup.Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels; soil pollution is majorly caused by industrial waste.
2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth’ surface causing melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation such as flash floods, excessive snow or desertification.
3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Intensive agriculture practiced to produce food damages the environment through use of chemical fertilizer, pesticides and insecticides.
4. Natural Resource Depletion:
Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change.
5. Waste Disposal: The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.
6. Climate Change: Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming which occurs due to increase in temperature of atmosphere by burning of fossil fuels and release of harmful gases by industries. Climate change has various harmful effects but not limited to melting of polar ice, change in seasons, occurrence of new diseases, frequent occurrence of floods and change in overall weather scenario.
7. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life.
8. Deforestation: Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and make that land available for residential, industrial or commercial purpose.
9. Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton in the same way as human osteoporosis.
10. Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s). Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer, the biggest of which is above the Antarctic. The CFC’s are banned in many industries and consumer products. Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth.
1.Natural Resource Depletion: Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy. The cost of installing the infrastructure and maintaining these sources has plummeted in the recent years.

Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth. This is one of the most important current environmental problem
6.Acid Rain: Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain can be caused due to combustion of fossil fuels or erupting volcanoes or rotting vegetation which release sulfur dioxide and nitrogen oxides into the atmosphere. Acid rain is a known environmental problem that can have serious effect on human health, wildlife and aquatic species.
7.Public Health Issues: The current environmental problems pose a lot of risk to health of humans, and animals. Dirty water is the biggest health risk of the world and poses threat to the quality of life and public health. Run-off to rivers carries along toxins, chemicals and disease carrying organisms. Pollutants cause respiratory disease like Asthma and cardiac-vascular problems. High temperatures encourage the spread of infectious diseases like Dengue.

ReplyDeleteOur environment is constantly changing. There is no denying that. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters, warming and cooling periods, different types of weather patterns and much more, people need to be aware of what types of environmental problems our planet is facing.
Global warming has become an undisputed fact about our current livelihoods; our planet is warming up and we are definitely part of the problem. However, this isn’t the only environmental problem that we should be concerned about. All across the world, people are facing a wealth of new and challenging environmental problems every day. Some of them are small and only affect a few ecosystems, but others are drastically changing the landscape of what we already know.
5 Major Current Environmental issue

BA THEOLOGY
In this article we are going to briefly discuss some of the most important environmental issues that the world is facing today due to human activities.
Our actions have negatively impacted the ecology and biophysical environment of the globe for decades. Ever since we started using carbon based fossils as a source of energy to fuel our industries, machineries, and homes, we have been impacting the globe through carbon emissions and other forms of pollution.
Carbon and other equivalent green house gases have already exceeded 400 parts per million, which is considered the tipping point, or the threshold, where greenhouse gases can cause harmful environmental changes. Below we will discuss top global impacts due to human activities.
Impact of human activities on climatic changes
When we connect the dots, we can easily find the correlation between global warming, climatic changes, extreme weather and effects on human health. The record heat, floods, droughts, forest fires, hurricanes and storms should make the message clear that we are doing something very wrong to the globe. Scientists are discovering that the extreme weather patterns are effects of global warming. The main reasons why our globe is getting hotter is carbon emission, greenhouse gases, and pollution.
Clean energy sources
Say “no” to dirty energy sources! The United States is the largest oil consuming nation in the world and we are at a crossroads today with choosing the right source of energy. Scientists predict that using fossil fuels as a source of energy will soon become a thing of the past. Using alternative sources of energy, such as wind and solar power, aren’t more costly than using fossil fuel and have long term environmental and health benefits. Renewable energy sources do not pollute the environment by emitting harmful gases, so we remain healthier. Our economy will prosper too if we create new jobs that do not depend on fossils and reduce global warming.

1. Air Pollution: Pollution of air, water and soil take a huge number of years to recover. Industry and engine vehicle fumes are the most obvious toxins. Substantial metals, nitrates and plastic are poisons in charge of pollution. While water contamination is brought about by oil slicks, acid rain, and urban sprawl; air contamination is created by different gasses and poisons discharged by businesses and manufacturing plants and burning of fossil fills; soil contamination is majorly created by mechanical waste that takes supplements out of the soil.
2. Water Pollution: Clean drinking water is turning into an uncommon thing. Water is turning into a monetary and political concern as the human populace battles for this need. Waste from industrial and agricultural activities pollute the water that is used by humans, animals and plants.
3: Soil and Land Pollution: Land pollution simply means degradation of earth’s surface as a result of human activities like mining, littering, deforestation, industrial, construction and agricultural activities. Land pollution can have huge environmental impact in the form of air pollution and soil pollution which in turn can have adverse effect on human health.
4. Climate Change: Climate change is yet another environmental concern that has surfaced in last couple of decades. Environmental change has different destructive impacts that include, but are not limited to, the melting of polar ice, change in seasons, new sicknesses, and change in general climate situation.
5. Global Warming: Environmental asset abuse is also an important environmental concern. Fossil fuel utilization brings about discharge of greenhouse gasses, which causes environmental change. However, individuals are taking endeavors to move to renewable energy sources.
6. Deforestation: Our woodlands create new oxygen and additionally help in managing temperature and precipitation. At present, timberlands cover 30% of the area, but wooded areas are being lost on a regular basis because people are looking for homes, food, and materials. Deforestation is a huge problem and will just continue to get worse.
7. Increased Carbon Footprint: Temperature increases, like climate change, are the consequence of human practices, including the use of greenhouse gasses. When the atmosphere changes and the heat increases, it can cause a number of problems and start to destroy the world we live in.
8. Genetic Modification: Genetic modification utilizing biotechnology is called genetic engineering. Genetic engineering of food brings about expanded poisons and sicknesses as qualities from a hypersensitive plant can exchange to target plant. Some of these crops can even be a threat to the world around us, as animals start to ingest the unnatural chemicals and such.
9. Effect on Marine Life: The amount of carbon in the water and the atmosphere is continuing to be a problem in the world around us. The primary effect is on shellfish and microscopic fish, and it has similar effects to osteoporosis in humans

Noise Pollution
What is it?
The noise pollution is defined as the unwanted sound which is released into the environment. It disturbs the human being and cause an adverse effect on the mental and psychological well being. It is measured in the units of decibels and is denoted by the dB. The noise which is more than 115 dB is tolerant. The industrial limit of sound in the industries must be 75 dB according to the world health organization. A type writer can produce a sound at 60 dB. There are different sources of the noise pollution and include the agriculture machines, industries which produce a sound and the use of entertaining equipment, crackers, the blasting of dynamite, bull dozing, stone crushing, defense equipments and textile mills.
Causes of Noise Pollution:
1. Industrialization: Most of the industries use big machines which are capable of producing large amount of noise. Apart from that, various equipments like compressors, generators, exhaust fans, grinding mills also participate in producing big noise. Therefore, you must have seen workers in these factories and industries wearing ear plugs to minimize the effect of noise.
2. Poor Urban Planning: In most of the developing countries, poor urban planning also play a vital role. Congested houses, large families sharing small space, fight over parking, frequent fights over basic amenities leads to noise pollution which may disrupt the environment of society.
3. Social Events: Noise is at its peak in most of the social events. Whether it is marriage, parties, pub, disc or place of worship, people normally flout rules set by the local administration and create nuisance in the area. People play songs on full volume and dance till midnight which makes the condition of people living nearby pretty worse. In markets, you can see people selling clothes via making loud noise to attract the attention of people.
4. Transportation: Large number of vehicles on roads, aeroplanes flying over houses, underground trains produce heavy noise and people get it difficult to get accustomed to that. The high noise leads to a situation wherein a normal person lose the ability to hear properly.
5. Construction Activities: Under construction activities like mining, construction of bridges, dams, buildings, stations, roads, flyovers take place in almost every part of the world. These construction activities take place everyday as we need more buildings, bridges to accommodate more people and to reduce traffic congestion. The down point is that these construction equipments are too noisy.
6. Household Chores: We people are surrounded by gadgets and use them extensively in our daily life. Gadgets like TV, mobile , mixer grinder, pressure cooker, vacuum cleaners , washing machine and dryer, cooler, air conditioners are minor contributors to the amount of noise that is produced but it affects the quality of life of your neighborhood in a bad way.
While this form of pollution may seem harmless, it in fact has far reaching consequences. The adverse effects on the health of the environment are quite severe. Not only is the local wildlife affected by the pollution, humans also face a number of problems due to it.
How to control Noise Pollution:
Sound-proof your space,
Keep noisy machines away from your bedroom and living areas,
Spend time away from noise,
Learn to meditate,
Use earplugs and noise-canceling headphones,
Install noise-reducing insulation and glass.

Current Environmental issues:
1.Natural Resource Depletion: Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy. The cost of installing the infrastructure and maintaining these sources has plummeted in the recent years.
2.Waste Disposal: The overconsumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries. Nuclear waste disposal has tremendous health hazards associated with it. Plastic, fast food, packaging and cheap electronic wastes threaten the well being of humans. Waste disposal is one of urgent current environmental problem.
3.Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and and loss of biodiversity. Ecosystems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the ecosystem and human activity threatens the same. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life.
4.Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton in the same way as human osteoporosis.
5.Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromine found in Chloro-fluoro carbons (CFC’s). Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer, the biggest of which is above the Antarctic. The CFCs are banned in many industries and consumer products. Ozone layer is valuable because it prevents harmful UV radiation from reaching the earth. This is one of the most important current environmental problem.
6.Acid Rain: Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain can be caused due to combustion of fossil fuels or erupting volcanoes or rotting vegetation which release sulfur dioxide and nitrogen oxides into the atmosphere. Acid rain is a known environmental problem that can have serious effect on human health, wildlife and aquatic species.
7.Public Health Issues: The current environmental problems pose a lot of risk to health of humans, and animals. Dirty water is the biggest health risk of the world and poses threat to the quality of life and public health. Runoff to rivers carries along toxins, chemicals and disease carrying organisms. Pollutants cause respiratory disease like Asthma and cardiovascular problems. High temperatures encourage the spread of infectious diseases like Dengue.

Noise pollution or noise disturbance is the disturbing or excessive noise that may harm the activity or balance of human or animal life. The source of most outdoor noise worldwide is mainly caused by machines and transportation systems, motor vehicles engines, aircraft, and trains.[1][2] Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution, since side-by-side industrial and residential buildings can result in noise pollution in the residential areas. Documented problems associated with urban noise go back as far as Ancient Rome.[3]
Outdoor noise can be caused by machines, construction activities, and music performances, especially in some workplaces. Noise-induced hearing loss can be caused by outside (e.g. trains) or inside (e.g. music) noise.
High noise levels can contribute to cardiovascular effects in humans and an increased incidence of coronary artery disease.[4] In animals, noise can increase the risk of death by altering predator or prey detection and avoidance, interfere with reproduction and navigation, and contribute to permanent hearing loss.[

CLIMATE CHANGE
While 97 percent of climate scientists agree that climate change is occurring and greenhouse gas emissions are the main cause, political will has not been strong enough so far to initiate a massive policy shift away from fossil fuels and toward sustainable forms of energy. Perhaps more extreme weather events such as droughts, wildfires, heat waves and flooding will convince the public to put more pressure on policymakers to act urgently to curb carbon emissions and address this issue before it’s too late.
POLLUTION
Air pollution and climate change are closely linked, as the same greenhouse gas emissions that are warming the planet are also creating smoggy conditions in major cities that endanger public health. If you’ve seen horrifying images of pollution-choked Chinese cities and think the smog is isolated to Beijing or Shanghai, think again. U.S. scientists are finding that Chinese pollution is intensifying storms over the Pacific Ocean and contributing to more erratic weather in the U.S.
Water and soil pollution might not get the media attention that air pollution does, but they are still important public health concerns. According to the Natural Resources Defense Council, dirty water is the world’s biggest health risk. While the Clean Water Act did much to make American water safe from harmful pollutants, today there is a new threat to clean water coming from the shale gas franking boom taking place across the country.
Soil contamination is a major issue across the world. In China, nearly 20 percent of arable land has been contaminated by toxic heavy metals. Soil pollution threatens food security and poses health risks to the local population. The use of
DEFORESTATION
Forests are important to mitigating climate change because they serve as “carbon sinks,” meaning that they absorb CO2 that would otherwise escape into the atmosphere and worsen global warming. It is estimated that 15 percent of total greenhouse gas emissions come from deforestation. Cutting down trees also threatens animals and humans who rely on healthy forests to sustain themselves, and the loss of tropical rainforests is particularly concerning because around 80 percent of the world’s species reside in these areas. About 17 percent of the Amazon rainforest has been cut down in the past 50 years to make way for cattle ranching. That’s a double whammy for the climate because cattle flatulence is a major source of methane gas, which contributes more to short term climate change than carbon emissions.
Water scarcity
As the population increases and climate change causes more droughts, water scarcity is becoming more of an issue. Only three percent of the world’s water is fresh water and 1.1 billion people lack a
LOSS OF BIODIVERSITY
Increasing human encroachment on wildlife habitats is causing a rapid loss of biodiversitythat threatens food security, population health and world stability. Climate change is also a major contributor to biodiversity loss, as some species aren’t able to adapt to changing temperatures. According to the World Wildlife Fund’s Living Planet Index, biodiversity has declined 27 percent in the last 35 years.
ccess to clean, safe drinking water. As the current drought in California dramatically shows, access to water is not just an issue for developing countries but the United States as well. In fact, by the middle of this century more than a third of all counties in the lower 48 states will be at higher risk of water shortages with more than 400 of the 1,100 counties facing an extremely high risk.

1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins released by industries and factories and combustion of fossil fuels.
essential nutrients.
2. Global Warming: Climate changes like global warming is the result of human practices like emission of Greenhouse gases. Global warming leads to rising temperatures of the oceans and the earth’ surface causing melting of polar ice caps, rise in sea levels and also unnatural patterns of precipitation
3. Overpopulation: The population of the planet is reaching unsustainable levels as it faces shortage of resources like water, fuel and food. Population explosion in less developed and developing countries is straining the already scarce resources.
4. Natural Resource Depletion: Natural resource depletion is another crucial current environmental problems. Fossil fuel consumption results in emission of Greenhouse gases, which is responsible for global warming and climate change. Globally, people are taking efforts to shift to renewable sources of energy like solar, wind, biogas and geothermal energy.
5. Waste Disposal: The over consumption of resources and creation of plastics are creating a global crisis of waste disposal. Developed countries are notorious for producing an excessive amount of waste or garbage and dumping their waste in the oceans and, less developed countries.
6. Climate Change: Climate change is yet another environmental problem that has surfaced in last couple of decades. It occurs due to rise in global warming
7. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and and loss of bio-diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Balance of natural processes like pollination is crucial to the survival of the eco-system
8. Deforestation: Our forests are natural sinks of carbon dioxide and produce fresh oxygen as well as helps in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost
9. Ocean Acidification: It is a direct impact of excessive production of CO2. 25% of CO2 produced by humans. The ocean acidity has increased by the last 250 years but by 2100, it may shoot up by 150%. The main impact is on shellfish and plankton in the same way as human osteoporosis.
10. Ozone Layer Depletion: The ozone layer is an invisible layer of protection around the planet that protects us from the sun’s harmful rays. Depletion of the crucial Ozone layer of the atmosphere is attributed to pollution caused by Chlorine and Bromide found in Chloro-floro carbons (CFC’s). Once these toxic gases reach the upper atmosphere, they cause a hole in the ozone layer
