　　Do you know that each day every person throws away 4.4pounds of trash？How much of that could be recycled？Maybe you should get to know the three Rs-Reduce，Reuse，Recycle．

　　One of the first things we should do to help protect the environment is to try to make less trash．Reduce your trash output（产量） by doing things like packing your lunch in reusable containers，and writing on both sides of your paper．

　　The next important thing to remember is to reuse．Think about the bags you get from the store．They can be reused to carry your lunch，as a trash bag，or even to collect cans for recycling．You can even take them back to the store the next time to carry your items instead of getting a new bag!

　　The third step is to recycle．Recycling is the most important part of keeping our planet clean and green．It can also save energy and resources．Be sure that you don't throw items in the trash that can be recycled．If you are not sure whether something can be recycled，ask your parents or teachers．
