^11^ Where are the animals future?

Today, when I was walking though the U of C, I saw four rabbits were playing in the grass ground. It makes me think that today, many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the development of cities, the using of insecticide and serious pollution, their living areas have become narrower and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. Therefore, measures of the following should be taken: pollution standards are made to keep down poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves. Only if we human beings take some drastic measures can wild animals be preserved.
