It is the year 3000. I come to a place where I can’t see any water, plants or animals but black clouds in the sky and sand everywhere. It’s very dry so I drink some water that I carry with me. A native sees what I do and asks “What is it?” I pour some water and tell him it’s called water. “Oh, I’m so lucky that I can see water” the man shouts in an excited voice. “You have never seen water? But how can you live without water? ” I ask.

“Harry, get up, it is 7 o’clock, or you will be late!” a voice comes to my ears. “Oh! What a strange dream I dreamed just now!”

In class, I always think of that dream. And I also think of the fresh air, clean water, blue sky, green plants and animals in our world nowadays. How beautiful our life is!

But in order to make more money, people have built more and more factories. These factories send out waste smoke and water with chemicals which are harmful to the environment. The pollution is becoming worse and worse, and as a result, some animals and plants die out. With the development of agriculture, farmers spray aerosol and fertilizer, which also pollute the water and air. In the street the cars and buses are sending out heavy smoke which pollutes the air badly. Even tourism is harmful to the environment. When some tourists travel somewhere, they throw the plastic bags and rubbish onto the ground.

These behaviors are polluting the environment and the environment will become the greatest problem of the world. We shouldn’t pollute the environment any more. Otherwise more and more animals and plants will disappear. And maybe my dream will come true in the future.
