Protect Wild Animals

    Animals are our good friends．We live in the same Earth．Animals and people can't  be separated from each other．But some animals are getting less and less．So it's important to us to protect animals，especially wild animals．Some people kill wild animals because of money．It's wrong．Now people need more places to live in．We explore the forest．  Animals have less places to live in．The number of wild animals decreases year by year．So we should protect wild animals．
