Animals are people's friends. But many of the wild animals are facing the danger of dying out. The Siberian tiger is one of them.Siberian tiger can be found forests in parts of Siberian and Northern China. The tigers are becoming extinct（灭绝）because people hurt many of them and are destroying their living places.
Another animal in danger is the Tibetan antelope（藏羚羊）. In the early 1990s, there were millions of Tibetan antelopes in China, but by the 1990s, the number of them had fallen to about 50.000. People hunt the antelopes for their wool.The wool of the antelope is soft, light and warm, and it is very expensive all over the world. Hunters can make a lot of money by selling their wool. The Chinese people have begun to protect the animals and seem to be winning. Now the number of the Tibet-
an antelopes is rising.
It's important to protect the wild animals. Now many wild zoos have been built in China. In the zoos we can see the animals we have heard of but have never seen. I think we can make friends with them by taking care of them.
