Saving the earth.
time goes by, man is making the earth sick. people cut down too many trees and leave rubish everywhere. factories let out their waste without doing anything to it. this has caused too much serious problem. for example, the land is sandy, the river is earth, thea air is less clean and the earth is having a fever.
what shall we do to save the earth ? we should plant more trees and put rubish into the dustbins. above all, stop factories from pouring waste directly into the air or the river.
after all.we have only one earth. we must try our best to save the earth, or we will be sad.
