Introduction of Environmental pollution
Pollution - Environmental pollution is any discharge of material or energy into water, land, or air that causes or may cause acute (short-term) or chronic (long-term) detriment to the Earth's ecological balance or that lowers the quality of life. Pollutants may cause primary damage, with direct identifiable impact on the environment, or secondary damage in the form of minor perturbations in the delicate balance of the biological food web that are detectable only over long time periods. Until relatively recently in humanity's history, where pollution has existed, it has been primarily a local problem. The industrialization of society, the introduction of motorized vehicles, and the explosion of the human population, however, have caused an exponential growth in the production of goods and services. Coupled with this growth has been a tremendous increase in waste by-products. The indiscriminate discharge of untreated industrial and domestic wastes into waterways, the spewing of thousands of tons of particulates and airborne gases into the atmosphere, the "throwaway" attitude toward solid wastes, and the use of newly developed chemicals without considering potential consequences have resulted in major environmental disasters, including the formation of smog in the Los Angeles area since the late 1940s and the pollution of large areas of the Mediterranean Sea. Technology has begun to solve some pollution problems (see pollution control), and public awareness of the extent of pollution will eventually force governments to undertake more effective environmental planning and adopt more effective antipollution measure Summary: In the previous project we was given some following points on environment pollution which are as given below-
1. Definition of pollution
2. Air pollution
3. Water pollution
4. Noise pollution
5. Land pollution
6. Effects of pollutions
7. Preventive measures
Future of environmental pollution.
Pollution occurs when chemicals and other foreign substances leech into the ground, air and water. These pollutants contain toxins that adversely impact ecosystems and the living creatures within them. Although environmental health and safety groups work to increase awareness of the danger pollution presents, if pollution continues at its current rate, the future effects could be devastating to human populations and the environment.
Pollution has an adverse impact on wildlife and will continue to do so well into the future. A 2004 report in "New Scientist" states that pollution is the primary cause of the extinction of various species of butterflies and other insects in Great Britain. Although pollution poses a threat to creatures on land, aquatic creatures may face an even greater danger. According to the Environmental Protection Agency, an estimated one to 11 percent of all marine species will fall into extinction every decade between 1975 and 2015. Water pollution comes from industrial and agricultural runoff and in addition to presenting a danger to aquatic life, water pollution also impacts humans -- since extinction of marine life adversely affects the food chain. Pollution occurs when chemicals and other foreign substances leech into the ground, air and water. These pollutants contain toxins that adversely impact ecosystems and the living creatures within them. Although environmental health and safety groups work to increase awareness of the danger pollution presents, if pollution continues at its current rate, the future effects could be devastating to human populations and the environment.
As pollutant levels increase, human exposure to toxins will also increase. The Environmental Protection Agency notes that exposure to pollutants is directly linked to cancer and heart disease. Air pollution is a primary problem in urban areas and for individuals who live near major roadways, since...
