  • Hello. This is 6 Minute English from BBC Learning English. I'm Neil.

  • And I'm Georgina.

  • Of all the weird and wonderful creatures living under the sea,

  • perhaps the strangest are jellyfishthose rubbery, cone-shaped creatures

  • found floating in the water, their long tentacles trailing behind.

  • Some jellyfish species have a bad reputation for scaring away tourists,

  • clogging up fishing nets, and even blocking power station pipes.

  • But with more and more plastic rubbish ending up in the sea,

  • these days you're as likely to swim into a plastic bag as a jellyfish.

  • Now scientific research is discovering that these rubbery sea creatures

  • might provide an answer -

  • a sticky solution to the problem of plastic pollution.

  • In this programme, we'll be learning how jellyfish mucus could provide

  • the answer to plastic waste in the seas.

  • And of course we'll be learning some related vocabulary along the way.

  • But first it's time for my quiz question.

  • Georgina, you mentioned jellyfish scaring away beach

  • goers with their sting, but what is the best way to treat jellyfish stings?

  • Is it: a) with ice?, b) with salt?, or, c) with vinegar?

  • Well, Neil, I have been stung by a jellyfish before and I think the best

  • way to treat them is, c) with vinegar.

  • OK, Georgina, we'll find out later if that's right.

  • Now, as I mentioned, in recent years tiny pieces of plastic

  • called microplastic have been a significant problem for the world's

  • seas and oceans.

  • They've been found all over the worldin Arctic ice, at the bottom of the sea

  • and even inside animals, including humans.

  • Slovenian scientist, Dr Ana Rotter, heads Go Jelly,

  • a European research team of jellyfish ecologists looking into the problem.

  • Here she is speaking to BBC World Service programme,

  • People Fixing the World:

  • Microplastics, plastics in general, are being an increasing problem

  • they're everywhere.

  • When I was a little girl we were more environmentally friendly,

  • not knowingso we never used plastic bags to go shopping,

  • we always went with a cloth bags, we never used plastic

  • to put our vegetable in it, single-use spoons, or forks, knives

  • this is for me something unheard-of when I was a little girl.

  • Dr Rotter says when she was a child, people were more

  • environmentally friendly - not harmful to the environment

  • or having the least possible impact on it.

  • At that time, there were very few single-use plastics

  • plastic items, like spoons and forks,

  • designed to be used just once, then thrown away.

  • Single-use plastic bags, for example, were unheard-of -

  • surprising or shocking because they were not previously known about

  • or commonly used.

  • The situation since then has changed dramatically.

  • In fact, there's been such an increase in microplastics

  • that today the UN lists plastic pollution as one of the world's

  • top environmental threats.

  • But how do jellyfish fit into the story?

  • Well, it's the 'jelly' part of jellyfish, and specifically their sticky,

  • jelly-like mucus that is key.

  • Here's Dr Rotter again, explaining more to BBC World Service

  • programme, People Fixing the World:

  • The mucusthis is a like a viscous substance

  • that is being excreted from a jellyfish, might have they are called absorptive

  • propertiesso it means that the particles - various particles can

  • attach to this mucusso, could we use jellyfish and their mucus

  • as a magnet for the microplastic particles?

  • Jellyfish produce a thick, sticky liquid called mucus.

  • Dr Rotter has discovered that this mucus has strong absorptive properties

  • it can absorb, take in liquids and other substances and hold them in.

  • One of the substances jellyfish mucus absorbs are the particles that

  • make up microplastics.

  • By trapping these tiny pieces of floating plastic,

  • the mucus acts like a magnetan object that attracts certain materials,

  • like metal, or in this case, microplastic waste.

  • As rising sea temperatures and overfishing of their natural predators

  • have boosted jellyfish numbers, this novel way of using their mucus

  • couldn't have come at a better time.

  • Dr Rotter's research is still in the early stages, but it's hoped that

  • jellyfish mucus could hold the key

  • to a future free of microplastic polluted oceans.

  • Which is a big prize for the cost of few jellyfish stings.

  • Speaking of which, Neil, what was the correct answer to your quiz question?

  • Right, I asked you the best way to treat jellyfish stings.

  • What did you say, Georgina?

  • I said it's c) with vinegar

  • Which isthe right answer! Well done.

  • Vinegar inactivates the sting's venom, so remember to pack

  • a bottle of vinegar the next time you head to the beach!

  • In this programme, we've been hearing how scientists are using

  • jellyfish mucus - a thick, sticky liquid produced in their bodies,

  • to break down microplastics in the sea.

  • Our addiction to single-use plasticsplastic items which are used

  • only once, then thrown away, and which often get washed out to sea,

  • has created a situation which is definitely not environmentally friendly

  • that means having minimal impact on the environment.

  • Until quite recently, the problems of micropollution and single-use

  • plastic were unheard-of - surprising or shocking because of not having

  • been previously known about.

  • Scientists are hoping that the mucus's absorptive qualities

  • it's ability to absorb liquids and other substances and hold them,

  • will allow it to trap particles of plastic floating in the sea,

  • making jellyfish mucus a magnet for pollution

  • an object that attracts certain materials - usually metals

  • but in this case, microplastic waste.

  • That's all for this programme, but to hear more about how

  • these amazing sea creatures could help clean our oceans,
