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 man's 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环境问题正变得越来越严重世界各地.随着工农业的发展,汽车制造噪音,排放毒气.山上的树木被砍伐,污水不断被排入河里.另外,无论我们走到哪里,我们就可以随意丢弃的垃圾.地球的整个生态平衡正在改变.环境的巨大破坏已带来负面影响,甚至严重 威胁到人类的生存,
我们必须正视存在的情况,并采取解决环境问题的行动.举例来说,新的法律必须通过把严格控制工业污染,酒吧!大众必须接受的教育有关污染的危害等.我们希望这些措施的有效实施能带给我们一个健康的环境
