不信啊 诺 看下面 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.

Directions: For this part, you are allowed 30 minutes to write a composition based on the following graph showing the growth of the world's population. The opening sentence is given and you are required to develop it into a full composition. Your part of writing should be no less than 120 words. Some useful words and phrases are provided, but you do not have to include all of them.(Suggested words and phrases: birth control, death rate, population explosion, food shortage)The Problem of Human Population It has been estimated that a thousand years ago there were less than 400 million people on earth. Today, however, the world's population has amounted to 5,000 million. What is worse, it keeps growing at a surprising speed. If this trend continues, the world's population will shoot up to 7,000 million by the year 2000. This is what we call population explosion. The rapid development of science and technology is the main cause of population explosion. We can see that the population has been growing at a tremendous speed since the Industrial and Agriculture Revolution in 1650, which raised the people's standard of living, and the emergence of modern medicine in 1550, which lowered the people's death rate. Population explosion will result in a lot of such problems as food shortage, housing shortage and unemployment. It is time that we acted quickly to carry out the policy of birth control otherwise, man's survival on the earth will be threatened.你再改改就应该没问题了.

污染特点——
环境污染是各种污染因素本身及其相互作用的结果。同时，环境污染还受社会评价的影响而具有社会性。它的特点可归纳为：
（1）公害性，环境污染不受地区，种族，经济条件的影响，一律受害。
（2）潜伏性，许多污染不易及时发现，一旦爆发后果严重。
（3）长久性，许多污染长期连续不断的影响，危害人们的健康和生命，并不易消除。
