Air Pollution

Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution.

Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less pollution.

Air pollution has a great effect on our health. Many people suffer from different diseases, such as asthma, bronchitis and lung cancer. We should do our best to reduce air pollution and improve the quality of air we breathe. For example, we can use public transportation, ride bicycles or walk instead of using private cars. We should also plant more trees and grass to increase the number of green spaces in the city.

In short, air pollution is a serious problem. We must take action to reduce it and protect our environment.
