19．Did you know that each day one person in the US throws away 4.4pounds of rubbish？Almost every month，we throw away our own rubbish in packaging alone．Packaging （including boxes，bags，etc） comes to our homes with the things we have bought．Several weeks ago，the TV news said that in a city in Italy tons of rubbish were piled up in the streets，and the smell was rather terrible．What can we do to help？We should get to know the following Rs．
Reduce To reduce means to make less rubbish．That is one of the first things we all should do for the environment．Reduce your rubbish by doing things like packing your lunch in reusable containers（ 可再利用的容器），taking smaller potions（份） at dinner so you don't waste food when you have had enough，writing on both sides of paper，and using less water when taking a shower．
Reuse To reuse is to use things again．Think about the bags you get from the store．They can be reused to carry your lunch，to hold your rubbish，or to collect used cans．You can even take them back to the store the next time to carry your things instead of getting a new bag!
Recycle （回收利用） Recycling is an important part of keeping our planet clean and green．It can also save energy．Be sure that you don't throw things in the rubbish that can be recycled to make something else．Paper，plastic，cans and bottles can all be recycled，but food，electrical waste and mobile phones can't．When you are not sure whether something can be recycled，go to your parents and teachers for advice．
Follow the three Rs，and every one of us can do something to save the earth．It is also the best way to save ourselves．
