Air pollution from human activities has created many problems for us. Pollution comes from many sources. The exhaust smoke from cars and truck is one cause of pollution. Another cause is the smoke that comes from factories. One of the main sources of pollution is the energy that we use. Coal, oli ang gas are used to produce electricity. These burning of fuel cause extensive pollution. They not only produce smoke but poisonous gases. Some big Cities a very polluted. There is white smoke and fog called smog covering the whole City. The health of people is affected by this smog. Besides people, plants are also affected. The wind carries the smoke and the gases into the country side. There, they affect the farms and lakes and the rivers. Plants and trees are destroyed and fish in the lakes die. Government are doing their best reduce air pollution. The atmosphere today is much better than it was fifty years ago. But all people must make an effort to try to reduce pollution further. In many place today, cars are not allowed in the centre of the city. People are encourage to use bicycles or to travel by public tansport.
