Animals are peoples friends. But many wild animals are facing the danger of dying out(滅絕)，because the environment that they are living in has changed greatly. For example, their living area is becoming narrower(狹窄的) and narrower because of the development of cities and pollution. They have no room to live in except the zoo.(除了動物園,它們沒地方可住了) And many wild animals now cant find enough food to eat. At the same time, man is killing off(殺盡) animals just for getting their fur, skin, teeth and meat.

People should realize how serious the situation is and something should be done to protect(保護) the animals. We are supposed to set up some nature reserves(自然保護區), so that animals can live freely. Besides, people should not be allowed to kill the endangered animals or eat their meat. We should do something to make our world cleaner. Fresh air, clean water and grass are all important for animals. The death of the endangered animals will bring a disaster(災難) to human beings.(人類)
