Aperçu du document
Effects on Humans : Adverse air quality can kill many organisms including humans. Ozone pollution can cause respiratory disease, cardiovascular disease, throat inflammation, chest pain, andcongestion. Water pollution causes approximately 14,000 deaths per day, mostly due to contamination of drinking water by untreated sewage in developing countries.
Oil spills can cause skin irritationsand rashes. . Older people are majorly exposed to diseases induced by air pollution.
Chemical and radioactive substances can cause cancer and as well as birth defects.
Effects on animals :Air Pollution can cause respiratory problems in animals other than humans. Smaller animals, as are small children, are more susceptible to distress from higher levels of sulfur dioxide and ozone inthe air. The greenhouse effect and global warming may be changing our climate faster than animal populations can adapt. Air conditioners and aerosol sprays that contain chlorofluorocarbons (CFC's)are contributing to a hole in the protective ozone layer
More than 1000 miles of Alaskan shoreline were contaminated with 11 million gallons of oil coating tens of thousands of sea birds andkilling at least 1000 sea otters. Since oil is nonpolar and insoluble in water, it is very difficult to clean. The area has been analyzed ten years after the event at A National Oceanographic andAtmospheric Administration Website.
Soil Pollution includes the abuse of pesticides like DDT. This nearly caused the extinction of several large birds like the brown pelican, but they have made adramatic recovery since DDT use in the US was banned nearly thirty years ago
Land Ecosystems are also affected by pollution. Bird populations have been changed by pesticides and oil spills. Bearsthat rely on fish diets can become contaminated. Mysterious mutations in frogs have been detected in the US. Habitat destruction is the primary reason for extinctions of animal populations.
