article on pollution
Answers
Answer:
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.
