It is important to learn how to protect our environment. Here is a 5 R rule for us: Reduce : If you want to reduce the waste, you should use things wisely. A large number of trees are being cut down to make paper. If everyone uses paperwastefully, soon we would not have any trees left. Other things are also being wasted, and people don ’ t know what to do with the waste in big cities. So it is necessary to reduce the waste. Reuse: You should always think of reusing the able things before throwing them away. Give your clothes you do not use or the ones which are too small to the poor. In a family, you may pass on such clothes to younger brothers or sisters. Recycle: Bottles, cans and paper cups can be easily recycled. By doing so, we can save lots of money. For example, coke cans are sent to a factory, where they are smashed( 粉碎 ) and melted and the metal things are made for new coke cans. Recover: When you buy a box of apples, there may be a few rotten ones, you have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. Repair: If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it is better for you to sell the old things or give them to other people who can use them after repairing them. It is true that North America is a “ throw away ” society, but the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.
