Environmental protection

People have thought that the environment is an unlimited source of resources, that the atmosphere, forests, rivers and seas are capable of absorbing all wastes. The environment supplies the economy of any country with its resources such as timber, minerals and oil. As a result, natural resources are becoming reduced, air and water are polluted, and the environment is unable to absorb all its wastes.

For example, waste gases cause acid rains. This leads to forest damage and therefore reduces the resources of forests. Another problem is water shortage resulting from unlimited use of it. The third one is destroying the ozone layer of the Earth through pollution from plants and cars. One more problem is damage to wildlife. It is possible that some kinds of animals can disappear due to people's activities.

Russia is suffering the environmental problems as well. Many of these problems are caused by economic activities. So, we should make our best to solve these problems and to protect our life and the life of further generations.
