As we all know the earth is the only place we can live on .So we should try our best to protect it .But there are some problems such as some kinds of pollution,hunting illegally and so on. I think we can do many things to protect the earth .First we should plant more trees to make our environment beatiful and can also fresh the air around us .Second we should turn to the newspaper to call on all the people to do something for our earth.Third we should forbid any kinds of waste.including the waste of water and the waste of electricity and food.Only in this way can we protect the earth and make it a better place to live.
