Сочинение по языку на тему загрязнение окружающей среды 7 класс. 30 .

Ecological problems are becoming more and more important today. People all over the world discuss environment pollution, but we still go on polluting air, water and soil. Air pollution is the biggest problem of large cities and industrial areas. It usually caused by different means of transport. Cars, buses and planes are among the worst air polluters. Factories throw rubbish in the rivers. As result trees and plants are poisoned so in one moment they will die. If we lose tropical forests it will become more difficult to breathe because they provide 50 per cent of the world's annual production of oxygen. Also, trees are threatened not only by pollution but by people. You should remember that when you throw something, it can eventually end up in a river. There is a way to reduce pollution from cars by using electric cars. We must not ignore the problems of pollution, and we have to try to make everything possible to stop or at least reduce the pollution.
