Today pollution is a very serious international problem. Almost everything is polluted in the world.
With the development of society, many factories have been build. They always send the poisonous smoke into the air and emit the waste water to rivers and seas, so we can’t breath the fresh air and drink the clean water. What’s more, as more and more people have cars, the was gas and noise from them has become a new pollutant. No wonder the strange diseases are everywhere.
If we continue to pollute our environment, our earth will be a terrible hell. So we must do something to protect our environment. For one thing, we should go to work by bus or by bike, in order to reduce the tail gas. For another, the waste gas and water must be done before they are sent out. What's more, we should plant more trees and flowers to purify the air. Only in this way can we prevent pollution and live a better life.

今天，污染是一个非常严重的国际问题，世界上几乎所有的东西都被污染了。
随着社会的进步，很多工厂已经建立起来，他们总是将有毒的烟雾排放到空气中，污水排放到河海中，所以我们不能呼吸到新鲜空气，喝不到干净的水。更重要的是，随着越来越多的人拥有汽车，他们已经成为一种新的污染，尾气和噪声。难怪到处都是怪病。
如果我们继续污染我们的环境，我们的地球将是一个可怕的地狱。因此，我们必须做些事情来保护我们的环境。一方面，我们应该乘坐公共汽车或骑自行车去上班，以减少尾气。另一个，废气和废水在排放前必须做处理。更重要的是，我们应该种植更多的树木和花草，净化空气。只有这样，才能防止污染和让生活变得更好。
