Once upon a time industrial goods were made to last forever. If you bought a car or a stove, it was a once-in-a-lifetime investment. You    51   (pay) good money for it, and you took good care of it. At the present time,    52  , industry has suggested that products shouldn’t last a long time. It’s cheaper to throw them away than    53   (repair) them. This has created a “throw-away society” which is

   54   waste of the earth’s resources. Just think of those pretty new second-hand cars that are sold daily. The owners get rid of them just    55   they are out of date. Think of the expensive packaging material that    56   (throw) away each time a new item is bought. And we have to pay for that material! This waste has got us into the trouble we are    57   now. When we have no resources

  58   (leave), we’ll then start to take care of    59   we have. But why can’t we act before this happens? Why can’t we go back to the society

   60   the prevention of waste is a virtue?
