　　The earth is the home of human beings. It's our duty to protect the earth. Let me tell you what I do. I always turn off the lights when I leave a room. While I am washing my hair, I usually turn off the shower. Besides, if I want to shop, I always take my own bags instead of using plastic bags. I have decided to do more things to protect our earth, such as recycling books and paper and stopping riding in cars. The earth is our home. I believe it will become more and more beautiful if we do something useful together.
