To read and talk about war on plastic packets.
To listen and read for general understanding.
To listen for specific information and understanding words in context.
To learn about and practise making and accepting suggestions.
To express solutions for unrecyclable shopping packaging.
Data released by the United States Environmental Protection Agency show that somewhere between 500 billion and a trillion plastic packets are consumed worldwide each year.
Less than 1% of bags are recycled. It cost more to recycle a bag than to produce a new one.
Plastic bags get blown around.
Plastic bags are in seas, lakes and rivers.
Plastic packets are in different parts of our lands.
Plastic packets have been found floating north of the Arctic Circle near Spitzbergen, and as far south as the Falkland Islands(福克兰群岛).

Advantage: It's convenient to buy meat or fruit or vegetables that are in packets or boxes because it makes shopping quicker and it keeps the products fresh and helps it last longer.
Disadvantage: It is wasteful as most people don't recycle
the packets.
A lot of things we buy in the supermarket are in plastic packets and boxes.
You are going to listen to two people, Kevin and Alicia, talking about plastic packets. Use the Skill Builder to decide whose opinion each statement is from. Write K (Kevin) or A (Alicia).

People can have different opinions on the same topics. It’s important to study these opinions, so that you can identify and understand the arguments for and against these important issues.
As you listen, identify the “topic” words or expressions of opinions and write down any opinion words you hear.
Pay attention to the intonation used when agreeing and disagreeing.

1. Work in pairs as Kevin and Alicia.
2. Use the information in table and add your own ideas.
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!
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.
Listen to the conversation and answer the following questions.
1. What are Lisa and Amy talking about in their conversation
2. What kind of wastes did they simply throw away that can be reused or recycled
3. Are they alone in action to protect the environment

2. What kind of wastes did they simply throw away that can be reused or recycled
They easily throw away newspapers and glass bottles.
3. Are they alone in action to protect the environment
No, there are lots of groups of people online who share ideas on how to reduce and recycle and who are committed to contributing to a better future for our planet.
1. What are Lisa and Amy talking about in their conversation
They are talking about how to become more environmentally aware.
Listen again and complete the table.

3.4 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.

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.

Group Work Online shopping is becoming more and more popular. However, it produces lots of unrecyclable packaging. What solution do you have to this problem
We can promote re-use and set up a reward model, offering an incentive (鼓励) for customers to return the packaging rather than throw it right away.
