Nowadays, rubbish sorting（分类） is a big problem now because there is too much rubbish. It's bad for our soil, air and water. Actually, we can use some rubbish again. First, we need to sort our rubbish. Here are some rubbish sorting and recycling around the world.
|
| Germany : There are big machines in supermarkets. You can put bottles in the machines and get money back. You can get one to two yuan per bottle. People like this because they can get money and protect the environment at the same time. |
|
| Japan: A trash truck（垃圾车） comes to people's doors to pick up their rubbish.Itplays music when it's coming. There are eight or more kinds of rubbish. If you sort any of them wrong, you will get a notice（公告）on your door. |

| Indonesia: People can take buses for free if they give plastic bottles to bus stations. An hour—long bus ride costs three large bottles or five medium bottles or ten plastic cups. But the bottles must be clean. |
