Animals are people’s friends. But many wild animals are facing the danger of extinction. The Siberian tiger is one of them. Siberian tigers could be found in forests in parts of Siberia and Northern China many years ago. But the tiger is becoming extinct, because people have hurt many of them and continue to destroy their living places. Another animal in danger is the Tibetan antelope. In the early 1990s, there were millions of Tibetan antelopes in China, but by the 1990s the number of them had fallen to about 70,000. People hunt the antelopes for their wool. The wool of the antelope is soft, light and warm, and 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 Tibetan 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 never seen. I think we can make friends with them by taking care of them.
