slide2

Since ancient times Nature has served Man, being the source of his life. For thousands of years people lived in harmony with environment and it seemed to them that natural riches were unlimited.

slide3

But with the development of civilization man\'s interference in nature began to increase.Large cities with thousands of smoky industrial enterprises appear all over the world today.

Every year world industry pollutes the atmosphere with about 1000 million tons of dust and other harmful substances. They are the main reason for the greenhouse effect and acid rains.

slide5

As a result some rare species of animals, birds, fish and plants disappear forever, a number of rivers and lakes dry up.

slide7

The seas are in danger. They are filled with poison: industrial and nuclear wastes, chemical fertilizers and pesticides. The Mediterranean is already nearly dead; the North Sea is following its fate. The Aral Sea is about to disappear. If nothing is done about it, one day nothing will be able to live in the seas.

slide8

And even greater threat are nuclear power stations. We all know how tragic the consequences of the Chernobyl disaster are.

slide9

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.

slide10

Environmental protection is of a universal concern. That is why serious measures to create a system of ecological security should be taken. Some progress has been already made in this direction.An international environmental research centre has been set up on Lake Baikal. The international organisation Greenpeace is also doing much to preserve the environment.

slide11

But these are only the initial steps and they must be carried onward to protect nature, to save life on the planet not only for the sake of the present but also for the future generations.
