Now the story There are more animals on the list of endangered species than ever before.

Around 2000 more creatures have been added to the red list of threatened species.

The figures were announced a cop 28, the annual International Climate Conference.

Scientists say climate change is putting the planet in a biodiversity crisis.

You ve been looking at the headlines film.

What's the vocabulary that people need to understand this new story?

In English, we have trickle captives and tipping points.

This is news review from BBC, learning English.

Let's have a look now at our 1st headline.

This is from the conversation Climate Change.

If warming approaches two degrees Celsius, a trickle of extinctions will become a flood.

Now, this headline talks about warming, that's global warming.

It says that if temperatures increase by two degrees, there will be even more species that could become extinct.

Now, we're looking at the word trickle.

This is related to water, isn't it?

Yes, it is. Um. A trickle is a very small flow of water.

So let's think about a bath.

If you've got a bath, and you turn it up a tiny little way, you'll get a trickle of water coming out of the tap.

Now, beth, what would happen if you left that trickle alone for a very long time?

Will the water would increase, increase, increase and flow over the top, and the bathroom would flood?

And, yeah, it wouldn't be good.

Yeah, it would become dangerous. Now, this headline is using trickle metaphorically.

As more species are added to the list of potential extinctions, and that's the trickle, it will become more dangerous for the planet.

That is the flood. That's right.

And we do often use the word trickle metaphorically to talk about a small number of things or a little bit of something.

And it doesn't have to just be a liquid, like in this headline.

OK, let's look at that again.

Let's have our next headline. This is from euro News.

Climate Captives The Winds and Losses of 2020 Threes Threaten Species List.

Now we are looking at the word captive in this headline.

It's in the plural form. Captives.

Phil what do you have in that mug?

I've got a spider. I captured it.

It's my captive. Now, a captive is something that's trapped.

It can be a person, or it can be an animal, like this spider.

I'll let it go now. Good.

Okay, so this headline mentions climate captives.

Does this mean, then, that these animals are literally trapped because of climate change?

Yeah, it does. Physically trapped, like my spider was, E.G.

rising sea levels mean that salt water is traveling up rivers, and that's trapping animals like frogs and salamanders, who they have less space to live, and that's why they're in danger.

Okay, so these animals are literally trapped by climate change.

They are climate captives. And we can also use the word captive for people, e.g.

if somebody is trapped or taken prisoner in a war, e.g.

let's look at that again. Next headline, please.

This is from E-I-N press wire, A biodiversity tipping point as 1st marine fish extinction declared.

Now, this new story is also about the list of threatened species.

It says that the world is at a biodiversity tipping point.

Phil can you explain tipping points for us?

Yes. Now it might help if we think about this visually.

So imagine a set of scales, and you keep putting weight onto one side of the scale.

What's going to happen? Berth Well, that side will tip over,

yes, and that is the tipping point.

Now, we often use this metaphorically, where there's

lots of small things keep happening until they reach a point where there's a big, significant change.

That is the tipping point, and it's usually negative.

So this headline is saying that it's a critical time.

We are at a tipping point where biodiversity is changing dramatically and for the worse.

Yes? Well, you often see this in new stories, and it is often negative.

You might see it in a story about inflation, e.g.

you could say that prices have gone up bit by bit until it reaches a tipping point, which might be where people can't afford to buy basic things.

E.G. that's right. OK, let's look about one more time.

We've had trickle, a small amount, which can increase captives trapped people or animals, and tipping points a critical time where things might suddenly change for the worse.
