Air Pollution And Climatic Changes.
If carbon dioxide is causing earth’s temperature to rise, it makes sense to get this form of pollution under control immediately. But is carbon dioxide pollution truly responsible? No one knows for sure. Earth warms and cools naturally over long periods of time. Many scientists believe that earth is now in a natural warming period. Neither carbon dioxide nor any other form of air pollution, they say, has anything to do with this trend.
Another concern is the thinning of the ozone layer. The ozone layer is a thick blanket of gas that
floats between ten and thirty miles (16-48 kilometers) above earth's surface. At ground level, ozone is harmful to life. In earth's atmosphere, however, this gas protects life by absorbing dangerous radiation from the sun. Without ozone, earth would be nothing but a hot rock where no plants or animals could survive.
In the 1980s scientists discovered that pollutants from earth's surface were rising all the way to the ozone layer. Once there, the pollutants were destroying ozone, especially over the Antarctic. As a result, people who lived in New Zealand, Australia, Argentina, Chile, and other regions near the Antarctic began to develop cancer at higher rates than did people in other parts of the world. This trend continues to the present day.
Taking a moment we would like to thank the environmentally concerned companies for continuously helping us with promoting sustainability , environment protection initiative and waste recycling and proper disposal of waste programs .
