It is important to learn about protecting our environment．Here is a 5R rule for us．

　　1．Reduce

　　If you want to reduce waste, you should use things wisely．A large number of trees are being cut down to make paper．If everyone uses a little paper carelessly and throw it out, 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．

　　2．Reuse

　　You should always think of reusing the usable things before throwing them out．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．

　　3．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 and the metal things are made for new coke cans．

　　4．Recover

　　When you buy a box of apples, there may be a few rotten(腐烂的)apples, you have two choices：one is to throw the whole apples away, or you could cut off the rotten parts and use the good parts．In this way, you are recovering the eatable parts of food．

　　5．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 doing some repair．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．
