Saving the Earth

As times goes by,man is making the earth sick. People cut down too many trees and leave rubbish everywhere .Factories pour their waste without doing anything to it. This has caused some serious problems. For example ,the land is sandy; the river is dirty; the air is less clean; even the temperature of the earth is rising,and she is shouting for help.What shall we do to save her？My suggestion is that we should plant more trees,put the rubbish into dustbins and stop factories from pouring waste directly into the air or rivers.In all ,we have only one earth we should do everything to protect it,or we will regret.
