| Ecological problems 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. But with the development of civilizationman’s interference in nature began to increase. Large cities with thousands of smokyindustrial enterprises appear all over the world today. The by-products of
their activity pollute the air we breathe, the water we drink, the land we grow
grain and vegetables on. Every year world industry pollutes theatmosphere with about 1000 million tons of dust and other harmful substances.
Many cities suffer from smog. Vast forests are cut and burn on 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. The pollution of air and the world’s oceans,destruction of the ozone layer is the result of man’s careless interaction with
nature, a sign of the ecological crises.
