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. The harmful wastes are buried and the waste water is cleaned before it goes into the river. The government has already made laws against pollution caused by rubbish. But that's not enough. We must all try our. best to prevent rubbish from polluting the environment so as to. save our city and our living place. 拯救地球处理城市垃圾是一个非常重要的问题。

首先，垃圾会导致污染。它会污染空气、水和人们居住的场所。其次，它会危害人类健康。所以我们在城市中，垃圾得到了妥善处理。我们首先将垃圾分类，然后可将旧报纸和玻璃制品进行再生利用。有害的废物要被掩埋，污水要在净化后才排入河流。政府已经制定了规章，禁止垃圾污染。仅仅这些还不够。我们大家必须竭尽全力防止拉圾污染环境以及拯救我们的城市，拯救我们的家园。
