It’s important to learn how we can protect the environment. Here are 5R rules for us.
Reduce If you want to reduce waste, you should use things more cleverly. A large number of trees are being cut down to make paper. If everyone uses paper carelessly, 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 amount (数量) of waste we produced.
Reuse You should always think of reusing things before throwing them out. For example, give the clothes you do not use or the ones that 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 can easily be recycled. By doing so we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat and melted. The metal can be used to make new coke cans.
Recover When you buy a box of apples, there may be a few rotten (腐烂的) ones. You have two choices: one is to throw the apples away; the other is to throw the rotten ones and keep the good ones. In this way, you are recovering the eatable parts of food.
Repair If one of the legs of your table is broken, you should repair it. If you want to buy something newer and better, it is better for you to sell the old thing, or give it to people who can use it after repairing it.
