At present ,many animals are in danger .For example:tiger.People kill them for their skins,meat,money and something else.But tigers are our friends and we should try our best to help tigers live in peace.As you know ,our villages and farms are growing bigger but tigers have less and less land to live.I think is a very important to built more nature raserves,then tigers will have ehough food to eat and enough places to live in.Of course,everyone should think about it.Let's do something right away,or it will be too late!
