Unit 22 Environmental ProtectionEnvironmental problemsEnvironmental 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.There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. The polluted air does great harm to peoples health. The polluted water causes diseases and death. What is more, vegetation has been greatly reduced with the rapid growth of modern cities. To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today. In my opinion, to protect environment, the government must take even more concrete measures. Firstly, it should let people fully realize the importance of environmental protection through education. Secondly, much more efforts should be made to put the population planning policy into practice, because more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves. As we all know, there is only one earth. The environment must be linked with social ethics, character education and practice acts Everyone must fulfil his responsibilities and obligations to protect the environment.环境问题全世界的环境问题正变得越来越严重。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，如今无论我们走到哪里，到处可见随意丢弃的垃圾。整个地球生态平衡正在改变。环境的巨大破坏已经带来了负面影响，甚至对人类生存造成巨大威胁。目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大地减少。为了保护环境，各国政府做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。依我看来，为了保护环境，政府应当采取更具体的措施。首先，应当通过教育使人们充分认识到环境保护的重要性。第二，应更加努力地把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。应该使他们知道破坏环境就是毁灭人类自己。众所周知，人类只有一个地球。环境要与社会公德、人格教育和实践行为联系起来。每个人都要履行保护环境的责任和义务。The earth is our home and we have the duty to take care of it for ourselves and for our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home
