Why is There Concern About the Environment?

You and all other living things on this earth exist in what is known as the biosphere. The biosphere includes those elements that support life-water, air, and soil.

Energy enters the biosphere in the form of sunlight. Plants need sunlight to make food. And all animal life on earth depends on plants for food. Without the air, water, and soil of the biosphere-and without sunlight-life on earth could not exist. It is essential, then, to keep these natural resources in the best possible condition.

Over the years, however, people have made changes that have affected the condition of the biosphere. For example, many, many trees have been cut down. This has caused soil erosion in many places, since tree roots help hold soil in place. Valuable soil is often washed into rivers and streams, which then become muddy and full of sediment.

Burning coal and oil to provide heat and to generate electricity pollutes the air with smoke, dirt, and gases. Still greater air pollution is caused by automobiles.

Modern technology is causing changes in the biosphere with a speed unique in all history. Many people have begun to think of these consequences of these changes, especially those that resulting various kinds of pollution. Some of the changes pose threats to the earth we live on and to the health of all living things on the earth. That is why people concerned today about pollution. And that is why efforts are now being turned to working for a healthier environment.
