Read for Understanding
K: On my way home from work yesterday, I stopped off at a local supermarket. Among other things, I wanted to buy a couple of coconuts. When I picked them up, I was amazed that each coconut was wrapped in clear, thin plastic. Isn’t this the most stupid example of packaging ever
A: You’ve picked an unusual example of packaging, but there is a reason for this. Supermarkets want to make sure that coconuts reach the consumer in the best condition. The packaging helps to keep the product fresh; it means the product will last longer.
（K=Kevin McCabe A=Alicia Stewart)
In the week when the government sets out its new environmental programme, Kevin McCabe and Alicia Stewart consider the problem of food packaging waste.
Tapescripts
（K=Kevin McCabe A=Alicia Stewart)
K: I understand that, but in this case it’s completely wasteful and unnecessary. I mean, why wrap a coconut in plastic It already has its own natural packaging. It’s got a tough shell that’s almost impossible to break!
Tapescripts
A: Yes, but the plastic wrapping also has other uses. For example, it stops coconut hairs from getting into other food during transport. And it keeps the coconut clean during the transportation process.
K: Is anyone really worried about a bit of dirt on a coconut And what about the environment A lot of the plastic used in packaging never recycles. It’s terrible for the environment: Our oceans are full of plastic waste, and animals and birds end up swallowing the plastic and dying as a result.
A: I have to say I agree with you on that. Some food packaging cannot be recycled, and that’s not good enough — the packaging should be changed so that it’s recyclable. But let’s be realistic: We still need packaging. We just need to use the right kind of packaging.
K: I think we need a more innovative solution. I really believe we should do away with packaging completely. There’s a supermarket in Germany that has no product packaging at all. Its customers take refillable containers with them when they shop, and use them instead of plastic boxes and bags.
A: It sounds like a wonderful idea, but I wonder how many people really shop there. I’m not sure most consumers would want to shop that way. It’s just not convenient.
The supermarket where you refill your own containers.
