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 people’s health. The polluted water causes diseases and death. What is more, vegetation had 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. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means 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.
保护环境
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,植被大大的减少。
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。
我的看法是,为了保护环境,政府应当采取更具体的措施。首先,应当通过教育的方法使人们充分謒到环境保护的重要性。第二,应更加努力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。使他们破坏环境就是毁灭人类自己。

(但是我们应该知道我们只有一个地球,如果它被摧毁了,我们就没有地方住了,所以我们不能坐视不理,我们应该做点什么来阻止继续这种破坏)
To make it ,we should do anything from ourselves ,such as not waste water or electic power etc.
(为了能成功,我们应该从我们自己做起,比如不浪费水电,等等)
Besides it we should persuade people joining us as more as posible.

环境被破坏的结果
环境污染会给生态系统造成直接的破坏和影响,比如:沙漠化、森林破坏,也会给人类社会造成间接的危害,有时这种间接的环境效应的危害比当时造成的直接危害更大,也更难消除。例如,温室效应、酸雨和臭氧层破坏就是由大气污染衍生出的环境效应。这种由环境污染衍生的环境效应具有滞后性,往往在污染发生的当时不易被察觉或预料到,然而一旦发生就表示环境污染已经发展到相当严重的地步。当然,环境污染的最直接、最容易被人所感受的后果是使人类环境的质量下降,影响人类的生活质量、身体健康和生产活动。例如城市的空气污染造成空气污浊,人们的发病率上升等等;水污染使水环境质量恶化,饮用水源的质量普遍下降,威胁人的身体健康,引起胎儿早产或畸形等等。严重的污染事件不仅带来健康问题,也造成社会问题。随着污染的加剧和人们环境意识的提高,由于污染引起 的人群纠纷和冲突逐年增加。
如何保护环境
1、 节约资源、减少污染。从点滴做起,节约利用资源。不使用或者少使用一次性饭盒、筷子等消费品,不浪费纸张,不浪费水电,随手关灯关紧水龙头,节约能源,做到资源的可持续利用。

2、 绿色消费、环保选择。使用环保电池,防止汞、铬污染,慎用洗涤剂,尽量用肥皂,减少洗涤剂中的化学物质对水的污染,认准绿色食品标志,选购环保食品。

3、 讲究卫生、保护环境。制止乱贴乱画、乱停乱放等不文明行为。不随地吐痰,不制造噪音。养成良好的卫生习惯,常开窗户多通风,勤换衣服勤洗手。不乱扔垃圾,正确处理好废弃物,对生活垃圾进行分类处理。

4、 保护自然、万物共存。不猎杀、食用珍惜动物和受保护动物,关爱救助野生动物。植树造林,爱护身边的每一份绿地、每一株花草、每一片树林。
