The earth is our home. We must take care of it. This means keeping the land and water clean.Pollution is a “dirty” word. To pollute means to make things dirty. Pollution comes in gugong.We see it, smell it and drink it. Pollution is bad for our health and even our life.Man has been polluting the earth from the time he first made his fire, washed his clothes in the river and throw his rubbish on the ground. Many years ago the problem was not so serious because there were not so many people. All the dirty things would soon be covered up. There was plenty of (美丽的)clean air, land and water. When the land was used up or the river was dirty in one place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Talking about pollution, we once only meant air pollution. It is true that air pollution is still the most dangerous now. But it is only one kind of pollution.
We are glad to say that many people have known this and they are working hard to stop polluting the earth.
