Environmental problems Environmental problems are becoming more and more serious all over the world. There are so many pollutions and natural disasters in the world. Pollution is, in fact, threatening our existence. The city is our home.Air and water affect everyone.So we have the duty to take care of it for ourselves and for our later generations. First,more and more people should concern about the environmental problems,such as teachers, students and city builders.Then,the giving off of the poisonous gas should be limited by factories.Finally, in order to seek benefits,some businessmen pollute the environment.Measures should been taken to cope with these problems by the government.So laws should been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better. 环艺四班 张婧 41106022221 本文来源：https://www.wddqw.com/doc/ba4497b804a1b0717fd5ddea.html
