V. Работа с текстом.
The poisoning of the world's land, air and water is one of the most important problems of our civilization. The seas are in danger. Many companies dump chemical and nuclear waste into water. The Mediterranean is already nearly dead; the North Sea is following. The Aral Sea is on the brink of extinction. Half of the lakes in the world are polluted. If nothing is done about it, one day nothing will be able to live in the seas.
Air pollution is also a very serious problem. Because many factories release sulfates into the air. When the sulfates mix with the clouds, acid rains fall and harm all living creatures. In Cairo just to breathe the air is like smoking two packs of cigarettes a day. Mexico City and 600 cities of Russia have dirty air. This causes different diseases. Because of different kinds of pollution every ten minutes one kind of animal, plant or insect dies out forever.
People begin to realize that environmental problems are our problem. These are a lot of international green organizations that take care of the environment and «Green Peace» is one of the most active. Many governments are waking up and making strict laws against pollution. Scientists are trying to make factories and plants cleaner. In many countries there are big plans to clean up the water. And every person must do his best to help our planet survive.
