¡¡¡¡As is shown by the two graphs, during the period of time from 1800 to 1900, with the explosive growth of the U.S. population, the number of species no longer existing shot up, amounting to 70 in 1990. It is apparent that the population explosion resulted in the sharp decline in the wildlife of the country. What brought about this phenomenon?

¡¡¡¡There are, I do think, two possible reasons for the fact. To begin with, the ever-increasing population needs more land to grow crops and more space to live in. Consequently, there is less and less niche in the U.S. for wildlife. Moreover, a number of newly built factories keep discharging harmful gases and liquids, which seriously pollute the environment. This has disturbed the ecological balance, contributing to the extinction of some wildlife.

¡¡¡¡In my view, three strong measures should be taken to solve the problem. In the first place, the birth rate in the U.S. must be put under control because the rapidly growing population leads to serious environmental crisis. Secondly, the U.S. government is supposed to create as many nature reserves as possible where all the native species of wild animals can be kept from being hunted and all the native species of plants can grow vigorously. Last and not least, it is urgent for the authorities to set up a foundation to reward those who do much to protect wildlife. (233 words)
