It had cans，bottles，broken glass and newspapers in itSince that first trip three years ago，Ive gone to the forest four times a year to pick up litterIm often there for three hoursIt makes me feel great to do something for the environmentAfter each trip，I look at all the litter Ive foundIf any of it is recyclable(可回收的)，I keep itI cant understand why people drop litterBut I will keep picking it up until they stop dropping itI know I can only do a small bit to help the earth，but I still think it is important( ) 1When did the writer begin to collect litter?

Americans throw away about 1 ton of rubbish per person every yearThats 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 usefulThe main things we recycle today are made from metal，paperPeople recycle for many reasonsOne 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 cansThis leads to a second reason people recycle：it saves energyRecycling old aluminum cans take much less energy than making new aluminumTo make new aluminum，you need to mine metal ore(矿石) from the ground，remove it，and refine it，into a finished metalRecycling also protects valuable landBy recycling，we produce less rubbishThat means fewer landfills are needed for dropping our rubbishBecause metals are some what costly to make，they are the worlds most recycled materialsAbout two-thirds of all steel(钢) is recycledAlmost all drink cans are made of aluminumAmericans recycle about one-third of their used aluminum cansEmpty cans are sent to special factoriesThere，they are cleaned，melted，and made into new pieces of aluminumAmericans use lots of paper mostly in the form of newspapers，magazines，and cardboard boxesIn fact，paper takes up more space in landfills than any other materialOld paper can be cut and made are into new paperAmericans recycle a little more than one-third of their paper rubbishNew papers are made from trees，each ton of recycled paper saves about 17 trees!( ) 6You can most probably read the passage in _Aa science book Ba Chinese boo
