In the week when the government sets out its new environmental programme, Kevin McCabe and Alicia Stewart consider the problem of food packaging waste.
(K=Kevin McCabe A=Alicia Stewart)
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: 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!
Tapescript:
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 l 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.

Wastes that can be reduced or reused
What Amy and Lisa decide to do in the future
Plastic bags
Takeaway food packaging
Cartons and plastic cutlery
Newspapers and glass bottles

Buy reusable shopping bags
Cook at home
Tell restaurants not to give any plastic cutlery, chopsticks or paper plates
Sort rubbish and take them to a recycling centre
Two friends, Lisa and Amy are discussing how to become more environmentally aware.
(A = Amy L = Lisa)
A: It's rubbish collection day tomorrow. I'll put out our bins.
L: Wow, we have so much rubbish! I just get anxious when I
think of the impact we have on the environment.
A: Me too! How can we have produced so much in just one
week? Look at all these plastic bags!
L: We really should buy reusable shopping bags when we go to
the supermarket. That would be a good start to reduce our
waste.
A: Let's do it. I also notice how much takeaway food packaging
we have. We should try to cook for ourselves more often.
Look at all these cartons and plastic cutlery! Cooking at
home is much more environmentally friendly.
Tapescript:
L: Well, I'm a terrible cook so it might be hard for me to cook
at home, but I think I will tell restaurants not to give me any
plastic cutlery, chopsticks and paper plates when I order
from now on.
A: That sounds like a good start. You know we are also quite
bad at sorting our rubbish - look at this newspaper for
example. It could easily be recycled but we threw it away.
L: And we threw away lots of glass bottles too. Let's sort our
rubbish and take it to a recycling centre from now on. The
local council will help to reuse and recycle it.
A: Wonderful! I think these are all realistic and achievable
steps that we can take to help protect the environment.
L: I've just looked online too and there are lots of groups we
could join which share ideas on how to reduce and recycle. It
feels good knowing that there are so many other people who
are committed to contributing to a better future for our
planet.
Online shopping is becoming more and more popular. However, it produces lots of unrecyclable packaging.
What solution do you have to this problem?

Useful expressions:
reuse; green packaging;
sustainable; reusable?…
E.g. We can promote reuse and set up a reward model, offering an incentive (鼓励) for customers to return the packaging rather than throw it in the trash.
