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 polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment.However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution.

求一篇关于拯救地球的英语作文范文 500词左右
拯救地球(Saving the Earth):英语作文范文 The population of the earth is increasing very fast. Humans must make the earth support the increasing population. This has made it necessary for agriculture and industry to develop rapidly. Such a rapid development produces more and more waste, which goes into the water, the soil and the air. Some of it is made harmless. However, where there is too much of it, the poisonous waste may do great harm to the things around the people. When farmers add fertilizer to the soil to make plants grow better, or use poison to kill pests, poison is sent into the air, the water and the soil. When birds, fish and people eat the grain, drink the water or breath the air, harm will be done to their health. The air in big cities is often made very dirty by cars and factories. Millions of tons of waste and poisonous gases are sent into the air with the smoke. In some places, little is done to make the smoke clean before it goes into the air. Fortunately, people are beginning to realize just how serious the whole situation is. In many countries, laws have been made to stop factories from sending out poisonous gases. Saving Our Earth It is very important to deal with the rubbish in cities. For one thing, rubbish may cause a lot of pollution. It may pollute the air, the water and the places we live in. For another, it may do harm to people's health. So in our city, rubbish is well dealt with. First, it is sorted. Then old newspapers and glass are recycled.
