【一起听英语】有害的塑料制品
塑料的危害很大....
Dan: Hello and welcome 6 Minute English from the BBC. I’m Dan Walker Smith
and today I’m joined by Kate.
Kate: Hello Dan.
Dan: Now today Kate and I are talking about pollution.
Kate: Yes, well pollution is the term for harmful waste which has been put into the
environment, and which can be damaging to plants and animals.
Dan: So I’m going to start the show today with a question, Kate; have you ever
heard of the ‘Great Pacific Garbage Patch 1’?
Kate: No, I’m afraid I haven’t; I’ve never heard of that.
Dan: Well let me explain: Garbage is an American word for something we’ve
thrown away. What we in the UK might call rubbish. And the Pacific
Garbage Patch is an area of the Pacific Ocean where rubbish has collected. It
was discovered in 1997, and is essentially 2 a big floating soup of plastic
garbage and bits of rubbish that have been thrown away on land and have
ended up in the sea.
Kate: Ooh that sounds absolutely horrible. I had no idea that anything like that
existed.

Dan: Well this is the bit which is really scary: we don’t actually know the size of the
garbage patch, but some people say it could be 600,000 square miles across –
which is twice the size of France.
Kate: What? Twice the size of France? That’s absolutely huge!
Dan: And it could be bigger.
Kate: That’s very frightening.
Dan: So this week’s question for you Kate is: According to the United Nations, how
many pieces of plastic are there in each square kilometre of the world’s oceans?
Is it:
a) 22,000 pieces of plastic
b) 38,000
c) 46,000
Kate: Well, as I’d never heard of this problem before, I’m going to take a wild guess
and, sadly, I think I’m going to guess the top number; 46,000 pieces of plastic.
Dan: OK, well they’re all pretty big, but we’ll see if you’re right at the end of the
programme.
Kate: Now plastic pollution in the seas kills over a million sea birds and 100,000
mammals and turtles each year.
Dan: So here’s the Dutch marine 4 biologist Jan van Franeker talking about the effects
of plastic pollution on birds. You’ll hear the word litter, which is another word
for rubbish. So what sort of litter have the scientists found in birds’ stomachs?

Worldwide, there’s so many bird species 6 that have litter in their stomachs. It varies 7
from pieces from bottles or toys, parts from fishing nets, from ropes. Any sort of plastic
really that is broken up and is floating around the ocean.
Kate: OK, so the plastics they’re finding 8 aren’t just things that might have been
thrown into the sea, like fishing nets and ropes, but are actually things that
have come from the land, like pieces of bottles and children’s toys.
Dan: Apparently 9 80% of all the plastic found in the ocean is actually litter that’s
been thrown away on land.
Kate: And part of the problem is that most plastics aren’t biodegradable. What does
the word biodegradable mean Dan?
Dan: Well, if something biodegrades it means it breaks down naturally. So if a
product isn’t biodegradable it won’t decompose 10 or decay 11 organically 12. And
some plastic bags could last in the environment for up to a thousand years.
Kate: Let’s hear the marine ecologist Richard Thompson talking about plastic
packaging. Packaging is the protective 13 covering used to transport products
and display a company’s image. So let’s have a listen to the extract: what
percentage of plastic produced each year is used for packaging?
Extract 2
I think we need to think very very carefully about the way that we use plastics in society.
If we think that 100 million tonnes of plastic products are made every year, 40% of
those are packaging materials that are mainly used once and then discarded 15.
Dan: OK, so 40% of the world’s plastic is used as packaging material and then
discarded. Can you explain what discarded means Kate?

Kate: Sure: well to discard 14 something means to throw it away. So if the packaging
is discarded, it means that people throw it away as rubbish or litter, rather
than use it again.
Dan: To lower the amount of plastic waste, scientists recommend the ‘three Rs’ for
packaging. We can reduce the amount of packaging used on products; we can
re-use packaging more than once, and we can recycle the materials used.
Kate: And recycle means to process used materials into new products. So you can
recycle old glass, paper and plastic products to make something new. Do you
recycle, Dan?
Dan: I’m actually very lucky, because where I live in London has a great recycling
programme. So essentially every week we’ve got someone who comes round
and collects all the paper and all the plastic and all the glass that I’ve used that
entire week, which is fantastic.
Kate: Oh that sounds great, you’re really lucky. Actually I’ve got the same thing: I
have all my plastics and glass picked up outside my house, so I think certain
places in the UK are doing quite well on the recycling front.
Dan: And even if you can’t recycle, just try and reuse or reduce the amount of waste
that you’re going to be producing.
OK, we’re almost out of time, so let’s go over some of the vocabulary we’ve
come across today:
pollution
garbage
rubbish
litter
biodegradable

Dan: And finally Kate, let's go back to today's question. I asked you at the beginning
of the show how many pieces of plastic there are in each average square
kilometre of the ocean?
Kate: And I went for c, 46,000.
Dan: Well, depressingly Kate, you’re right. There are apparently 46,000 pieces of
plastic, on average, in each square kilometre of the ocean.
Kate: What? 46,000 pieces of plastic? That’s absolutely incredible 16! How sad, and
think of the damage that must be doing to the sea life.
Dan: But, hopefully, if we all try and reduce waste, and use less packaging, and
recycle more, then maybe things will get better.
So from all of us here at BBC Learning 3 English, thanks for listening, and
goodbye!
Kate: Goodbye!
