Task 1. Reading Environmental problems is the most burning problem of today. The ecological problem influence the climate on the Earth. Mankind long believed that, whatever we did, the Earth would remind much the same. Nature is under threat. Our country’s pollution can be every country’s problem. So we all need to work together to safeguard our environment.
Air pollution is a very serious problem. Industrial enterprises emit tons of harmful substances. They are the main reason for the greenhouse effect and acid rains. The pollution of air and the world’s ocean, destruction of the ozone layer is the result of man’s careless interaction- with nature a sign of the ecological crises. Rains, full of acid chemicals, change lakes, rivers, as well as forests. Acid water kills the plants and animals that usually live in water. Acid rain makes the Earth more acidic and some kinds of trees can’t live in the sol that is very acidic. Forests are disappearing and this upsets the oxygen balance. Water pollution occurs mostly, when people overload the water environment such as streams, lakes, underground water, bays or seas with wastes or substances harmful to living being.
Nuclear weapon is also course of the pollution. It brings a great damage to the agriculture, forests and people’s health.
The greenhouse effect and global warming both correspond with each other. The greenhouse effect is recalled as incoming solar radiation that passes through the Earth’s atmosphere but prevents much of the outgoing infrared radiation from escaping into outer space. It causes the overheat of the air as a result we have the global warming effect.
People are beginning to realize that environmental problems are not somebody else’s. In many countries environmental protection agencies and research centers are up. Such organization as “Green Peace” cares for ecology in countries. Its main goal is to combine the people’s efforts for peace with the huge and ever mounting movement launches all kind of environmental actions and inform of the ways, means and results of this work.
