Question

When your pen is broken, you think that's the end of its life. You throw it away. It then joins tons of other rubbish that is becoming a big problem in cities. This happens in other countries, too. Most Americans are making 7 pounds (3.17kg) of rubbish a day. So, an American makes about 102 tons of rubbish in a lifetime.

If you simply throw away that broken pen, it goes to a landfill (垃圾填埋場) and is buried with other rubbish. To prevent polluting the groundwater, workers cover the rubbish with soil and keep it dry. And your pen will stay there for a long time, without having further use. But it could have a better place to stay in -the recycling bin. Have you ever noticed the different colors of rubbish bins in the street? Many cities in China have been running a waste-sorting campaign (垃圾分類運(yùn)動). "They divide rubbish into "recyclable waste" and unrecyclable waste". Recycling waste can save energy, reduce (減少) greenhouse gas and keep landfill space free for unrecyclable waste.

Take your pen as an example. At the recycling factory, its metal parts could be taken out and reused to make other things.

But according to the experts, recycling is not enough. Making less waste should be put in the first place. They think that the best thing to do is just to keep using your things for as long as you can.
