You left all sorts of good stuff.

But then we went and did a proper job and actually cleaned it up.

So there's absolutely nothing there now.

So why do you want to go and see it?

I said, well, I want to go and see it, look at the landscape and explain about fossil reefs and one thing or another.

So rather reluctantly, I have to say, he and I and the film team got a helicopter and we went off.

And when we landed, I went out first and I stood on a lump of rock about a foot across.

And on it there was a most extraordinary rectangular plate with lovely pattern on the surface.

I hadn't the faintest idea what it was.

And he, the geologist, came after me and I said, ''What on earth is that?''

And he said...

You bastard.

It wasn't.

It was.

It was one of the bits of one of these fish that he said he had cleared up.

However, he was a good bloke.

He'd let me keep it.

So there it is, and it's one of the head scutes of one of those enormous armoured fish that were swanning around in the Devonian period.

Yeah, it's an amazing trove.

Going towards the coast, the Great Barrier Reef, of course, is also in jeopardy, and, of course, there the problem is not just one element, maybe climate changing, but several, overfishing, the pollution from the land, and even a structure 2,500 kilometres long cannot withstand three attacks at once.
