Passage 48
Population Growth
It is well-known that there has been a drastic increase in world population. But it is probably less well-known that the extinction¹ rate of wildlife species is experiencing a parallel trend.
Take the United States for instance. In 1990, U.S. population reached an unprecedented² 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 1900, about 70 wildlife species would never be seen in U.S.. We are fully³ justified⁴ in declaring that the explosive population growth has had an adverse⁵ effect on the survival of wildlife species and will be a constant threat to the wildlife resources if no immediate⁶ 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 demolishing⁷ the environment we are living in. (152 words)
