求一篇关于空气污染的英语作文，80字左右
解题思路： 围绕话题展开，从危害和解决办法入手，语句通顺，表达流畅。
解题过程：
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.
We all know that clean air is important to good health. If there are impurities in the air, they may be absorbed by our bodies and make us ill. We need clean air, but unfortunately , air pollution is globally present , especially in cities. Our cities have many factories, which we need to make food, clothing and other things. Every year these factories pour millions upon millions of tons of smog into air. Power plants and houses that burn coal add greatly to air pollution. Besides , there are more cars in cities now. Once out on the streets, they will take in fresh air and replace it with poisonous gases.
