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

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
