Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down,and waste water is being poured continuously into rivers. Furthermore,wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to mans existence.

We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures will be effective and bring back a healthful environment.
