From what has been discussed above, we can do something to our home—the earth. We should make full use of things. At the same time, we’d better reduce its harmful effect as much as possible.

　　We can do from the basic of waste. That’s to say, we can reduce the production of waste, and reuse and recycle them as much as we can. Take material waste for example. Nearly all of them can be recycled and reused. And, we should call for using things made of paper instead of plastics so as to protect our environment.

　　Protecting the environment is not one person’s duty; it depends on all of us. What can we do? Maybe a dozen..

　　In a word, use what can reuse as much as possible. Remember, environment protection is not one’s duty!
