Our earth was healthy and beautiful in the past. However, it’s getting dirtier and warmer now. Natural disasters happen more often than before.Animals and plants are in danger.

Why does this happen? First, there are more and more people on the earth. Second, people keep cutting down forests and killing animals for their fur or bones.

What can we do to help the Earth?I think everybody can do something to help save the earth. For example, we shouldn’t eat wild animals. We can also use both sides of the paper and plant more trees.What's more,we should encourage people around us to do so.

　　I hope our earth will become more and more beautiful if we take action to protect it.
