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 ha一ve 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.

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.

Currently, there is a widespread concern about the previously neglected connection between growing human population and decreasing wild species. As the two graphs obviously portrayed, American population in 1980 was 250 times than that in 1800, a trend accompanied by the extinction of nearly 70 kinds of wildlife in the past 300 years. A clear correlation is suggested that mankind has exerted a tremendously negative influence on natural species.
There are many factors responsible for the aforementioned tendency. First and foremost, to satisfy the space demand for the booming population, the only a一vailable solution for Americans is to take occupation of forests and grassland. that used to be habitat of wild animals and plants. Furthermore, the process of industrialization and urbanization has generated severe pollution that essentially destroys environment and ecosystem.
In my point of view, the dearth of wildlife today forecasts an unpromising future for humans tomorrow. In order to eliminate species extinction, relevant laws and regulations must be established and enforced to maintain a large portion of unspoiled areas. Effective measures should also be applied to ensure that the impact of pollution be removed.
