Animals in danger

This book made me think of wold animals in danger. I recommend you to read it!!
There are more than thirty million species of animal in the world. But recent year, some of them disappear and we never see them again. Why are animals in danger? The reasons are pollutions and cutting down forests.　On land, rhinoceros die because people want thier horn. In the water ,fish die in a dry river. In the sky, pollution kills birds. What can I do? The thing what we never forget is humans and animals live in one world. So our home is their home. We need to think of this and do what we can.
