| In the world today, pollution has become a serious problem facing man and his plan-et. The air, seas, rivers and soil have been seriously polluted by all kinds of waste and poisonous matter. It does great harm not only to human beings but also to aninmls and plants. We can’t have fresh air. Fish died front polluted water. It is reported that strange diseases havc appeared in many places because of pollution. I hope that all the people in the world will take necessary steps and effective measures to solve this serious problem. We arc looking forward to the coming of the day when we see pollution effectively con-trolled and air cleaned. It is indeed our urgent task to do everything possible to protect our ecological environment and to keep nature in good balance. |
