We put so much stress on these ecosystems that they reach a tipping point beyond which they cannot survive.

You know, for instance, if you're talking about the Amazon, it could reach a tipping point where it turns from a rainforest and

into a savannah, which would have just global consequences.

Coral reefs beginning to die off at a really dreadful level, and that has an impact on fisheries and so on, and marine ecosystems.

And the thing about these tipping points is that

When you know you've reached them, it's too late.

You know, the groundwork for that is laid decades in advance.

And it's only when the tipping point has actually been reached and it's irrecoverable that you know about it.

So we could be unknowingly going through kind of triggering all these tripwires, essentially, the consequences for which will hit us further down the line.

Oh my goodness.

So we know that one of the Prime Minister's advisers, who recently left for other reasons...

Morgan McSweeney, we know that he was never very keen on anything that involved the environment or the climate or net zero, anything like that.

I think he felt that it wasn't something that the government was going to win votes on.

I think he felt that these are subjects that come under attack from sections of the media and from the Reform Party and the Tory party.

I think he just takes a look at things, says, oh, it's got climate on it.

Well, let's not have that.

I have to say that this government has tended to be very secretive about a lot of things and a lot of things environmental.

I mean, they rarely hold press conferences.

It's rarely possible to actually question ministers on these issues.

And that astonishes me.
