Слайд 2Since 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. But with the development of civilization man's interference in nature began to increase.
Слайд 3The by-products of their activity pollute the air we breathe, the
water we drink, the land we grow grain and vegetables on.
Слайд 4Every year world industry pollutes the atmosphere with about 1000 million
tons of dust and other harmful substances. Many cities suffer from smog.
Слайд 5 Vast forests are cut and burn in fire. Their disappearance
upsets the oxygen balance. As a result some rare species of animals, birds, fish and plants disappear forever, a number of rivers and lakes dry up.
Слайд 6The most horrible ecological disaster befell Ukraine and its people after
the Chernobyl tragedy in April 1986.
A great damage has been done to the agriculture, forests and people's health. The consequences of this explosion at the atomic power-station are tragic for the Ukrainian, Byelorussian and other nations.
Слайд 8But 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.
