The Earth is like our mother.She gives live to all the living things on the Earth.And she provice us with air、food、water and other things we need for living.Once she was beautiful ahd rich.But mow she is crying,becacuse she is becoming dirtier and dirtier ,poorer and poorer.It's our duty to protect our Earth.So we must stop pollution,plant more trees and keep our enviroment clean.The Earth is our only home.It's very important to take good care of her.Saving the Earth is to save ourself.
