　　Population Growth

　　It is well-known that there has been a drastic increase in world population. But it is probably les

　　well-known that the extinction rate of wildlife species is experiencing a parallel trend.

　　Take the United States for instance. In 1990, U.S. population reached an unprecedented level of 250

　　million, which is approximately 250 times of that of 1800. On the other hand, wildlife species are

　　disappearing from the country at an alarming rate. By 1990, about 70 wildlife species would never be

　　seen in U.S. We are fully justified in declaring that the explosive population growth has had an adverse

　　effect on the survival of wildlife species and will be a constant threat to the wildlife resources if no

　　immediate actions are taken.

　　Nothing has ever equaled the magnitude and speed with which the human species is altering the

　　physical and chemical world. It has been demolishing the environment we are living in.

　　Useful words and expressions:

　　parallel 平行的

　　trend 倾向

　　unprecedented 空前的

　　magnitude 大小，数量

　　alter 改变

　　demolish 毁坏
