Earth is a place for us to live on,and we can hardly find another planet like her.If we don’t take care of her,we will not have any room to live.
So it’s our duty to save the earth,our mother.First,we can use as less paper as we can because paper is made form wood and wood is form trees.Next,we can save the water to do other useful things.
We have many ways to save the earth,why not do some of them.The future is up to you to change.
