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.

To begin with, as the population grows, people consume much more natural resources, which often leads to excessive hunting. Second, with the increase of human activities, modern people take up more and more space. Which has a great impact on other species. Finally, the problem of pollution becomes more and more serious with the development of modern industry. More and more animals have to adapt themselves to the decaying environment or move to a totally different place, but not all of them are fortunate enough to survive the changes.

Solving this problem calls for, above all, the government’s efforts to control population growth, to decrease industrial pollution and to enhance the laws to forbid wildlife hunting. Moreover, common citizens should be aware of this ecological crisis and take on the responsibility of wildlife protection. In a word, only when the government and the common people make joint e f forts can we hope to find a satisfactory solution to this problem.

首先，随着人口的`增长，人们消耗更多的自然资源，这往往导致过度狩猎。其次，随着人类活动的增加，现代人占据了越来越多的空间。这对其他物种有很大的影响。最后，随着现代工业的发展，污染问题越来越严重。越来越多的动物必须适应退化的环境，或者搬到一个完全不同的地方，但并不是所有的动物都有幸在变化中幸存下来。

解决这个问题首先需要政府努力控制人口增长，减少工业污染，并加强法律禁止野生动物狩猎。此外，普通市民也应该意识到这一生态危机，承担起保护野生动物的责任。总之，只有当政府和百姓共同努力，才能找到一个令人满意的解决办法。
