Because of human destruction (破坏) and other factors (因素), the endangered animals on the Earth is getting fewer and fewer.

    The tiger, the world's largest cat, is close to extinction (灭绝). There are only about 6,600 of them in the world. More than 150 bird species (种类) have died out since 1500.

    World Animal Day is coming near. What should we do to protect animals? First, we should raise people's awareness (意识) to protect animals and our environment. We should call on (号召) people to protect animals. Second, we must take some measures (措施) to protect animals effectively (有效地). Third, I think that we should do more to protect animals. Because we are a family, everyone should get together to protect animals.
