老师：Hello everyone, I'm Yue from Beijing Academy, Chaoyang Districts. Nice to see you today. We are going to continue with Unit 3, conservation listening wool on plastic packets. Let's have a discussion first. Do you often use plastic bags and boxes? What are the advantages and disadvantages of using them? Use the phrases below to help you. For example, you can say that a lot of things we buy in the supermarket are in plastic packets and boxes. They are very convenient to use and easy to carry around. All you can say plastic packaging is very terrible for the environment because it is not degradable. In fact, plastic packaging is just the topic of the conversation we are going to listen to today. Let's listen for the first time. While listening, think about the following questions.
学生：Lesson 2,3.3, in the week when the government sets out its new environmental program, Kevin Mccabe and Alicia Stewart consider the problem of food packaging waste.
学生：On my way home from work yesterday, my stopped off at a local supermarket, among other things, and 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?
学生：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.
学生：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.
学生：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.
学生：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. Mar oceans are full of plastic waste and animals and birds end up swallowing the plastic and dying as a result.
学生：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.
学生：Now, I think we need a more innovative solution and 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 bag
