Nowadays, environmental problems are the most burning for the society. Air, water, land and nuclear pollution badly damage the nature. People cut down trees and destroy the habitat of thousands of animals. As a result, many species are in danger of extinction. Factories pollute our rivers and lakes with dangerous chemicals. The increasing number of cars in towns and cities has led to the growth of harmful gases in the atmosphere. There is much litter everywhere, our parks and forests are full of rubbish.
