What can we do to protect pandas?
        Pandas are Chinese national treasures. They live only in China. However, they are endangered animals. One of the reasons is that people are cutting down many trees to build their houses.And the bamboo is becoming less and less. Another reason is that people have hunted a lot of pandas for their fur. 
       I think we should do something to protect pandas. For example, we should set up nature reserves. We should not buy clothes made of fur. If we can do these, I think there will be more and more pandas.
