Our Earth is a wonderful planet. Since ancient times Nature has served Man. Nature is a source of his life. For thousands of years people lived in harmony with the environment. But nowadays they say the Earth is in danger.

There was no ecological problem until people built lots of plants and factories which sent wastes into the air, water and land. These chemical substances do not disappear but last forever in one form or another. Modern people live only according to their wants, they ignore the laws of nature. And such a situation is dramatic.

People are slowly destroying the nature environment around them. Every year world industry throws out into atmosphere about 1 000 million tons of dust, smoke and other harmful substances.
