Think of all the things you throw away：juice bottles，soda cans，candy covers．It adds up．How much rubbish do you produce Americans throw away about 1 ton of rubbish per person every year．That's 2000 pounds of rubbish! Most of the rubbish gets covered in big holes in the round called landfills(垃圾掩埋法)．
A lot of this rubbish can be recycled，or turned back to something useful．The main things we recycle today are made from metal，paper．
People recycle for many reasons．One of the main reasons is to protect resources(资源)．Making new cans out of old ones means less aluminum(铝) is needed for new cans．The main things we recycle today are made from metal，paper．
This leads to a second reason people recycle：it saves energy．Recycling old aluminum cans take much less energy than making new aluminum．To make new aluminum，you need to mine metal ore(矿石) from the ground，remove it，and refine it，into a finished metal.
Recycling also protects valuable land．By recycling，we produce less rubbish．That means fewer landfills are needed for dropping our rubbish．
Because metals are some what costly to make，they are the world's most recycled materials．About two-thirds of all steel(钢) is recycled．
Almost all drink cans are made of aluminum．Americans recycle about one-third of their used aluminum cans．Empty cans are sent to special factories．There，they are cleaned，melted，and made into new pieces of aluminum．
Americans use lots of paper — mostly in the form of newspapers，magazines，and cardboard boxes．In fact，paper takes up more space in landfills than any other material．
Old paper can be cut and made are into new paper．Americans recycle a little more than one-third of their paper rubbish．New papers are made from trees，each ton of recycled paper saves about 17 trees!
