Ⅲ.　 The earth is our home and we must take care of it. That’s to say we must keep the land, air and water clean. But man has produced lots of pollution on the earth since he first made a fire, washed his clothes in the water and threw waste or litter on the ground. Many years ago, pollution wasn’t so serious because there weren’t so many people.

There once was enough clean air, land and water. When the land or the river was dirty in one place, man moved to another place. The more people in one place, the worse the environment they maybe have.

Perhaps you’re afraid it’s endless for people to produce pollution. Luckily, we’re glad to tell you that people have come to know the danger of pollution and more and more people are working hard to protect our earth.
