保留土地给濒临绝种的动物英语四级作文

　　there is only so much land on the earth, and so what we can do with it is limited. some people believe that human needs for farmland, housing and industry should come first, while others believe that some land should be set aside for endangered animals. i am of the opinion that we should reserve some land for the worlds animals for the following reasons.

　　first, mankinds need for land is constantly growing. if the demand is not checked in some way, humans will eventually develop all of the earths available land. at that time, mankind will have no more room to grow, and all the wild animals will have disappeared, as well as other valuable resources. second, humans are able to innovate and can use the land that they already possess in more efficient ways. animals are unable to do this. once their land is taken away from them they will die. third and last, endangered animals are an important part of the biodiversity of our planet. if they disappear, we cannot predict what the effect will be. therefore, we should treat such animals as a valuable resource to be protected.

　　to sum up, the worlds endangered animals are an important resource and we should protect them by setting aside some land for them. although mankinds need for land continues to grow, people are intelligent and inventive enough to put the land they have to better use. in this way, we can have enough land for farming, housing and industry, and preserve the biodiversity of the planet at the same time.
