The Plastic Problem

What to do: Read this short extract from the unit article. Then answer the questions and tap Check Answers. (Read the full article using the link above!)

Every year, the world produces around 350 million tonnes of plastic waste. Much of it is "single-use" — a bottle or bag we use once and then throw away.

The good news is that plastic is one of the easiest problems to fight. If everyone carried a reusable bottle, we would throw away far less plastic.

1. About how many tonnes of plastic waste does the world produce each year?
2. "Single-use" plastic is used ______ and then thrown away.
3. What would happen if everyone carried a reusable bottle?

Audio 2Lena and Max talk about a recycling project

Lena: Hey, did you hear about the new recycling project at school?

Max: No, what is it?

Lena: They're putting recycling bins in every classroom — for paper, plastic, and cans.

Max: That's great. Our school throws away so much plastic.

Lena: I know. If everyone used a reusable bottle, we wouldn't need all those plastic ones.

Max: True. I always bring my own bottle now. What else can we do?

Lena: We could turn off the lights when we leave a room. And the school wants to plant trees in the spring.

Max: Nice! If I had more time, I would join the gardening club.

Lena: You should! Small actions really add up.

Max: You're right. I'll start with the reusable bottle and turning off lights.

Writing

A Problem & a Solution

What to do: Write about one environmental problem and how to solve it (about 80–100 words). Use the second conditional. There is no automatic score — use the checklist.
Example: "One big problem in my town is plastic waste. People use too many plastic bags and bottles. If shops charged money for plastic bags, people would bring their own. If our school had more recycling bins, we would recycle more. I think small changes would make a big difference. If everyone helped, our town would be much cleaner."
