Big cities suffer from smog from large factories. Cars with their engines have become the main source of pollution in industrial countries. The forests Africa, South America and Asia are cut down for the needs of industries in Europe and the USA. As a result some species of animals, birds, fish and plants have disappeared and keep disappearing. Rivers and lakes dry up. One of the most known examples is the Aral Sea, which has become much smaller due to men’s activity.
