We have to have backup, which is enormously expensive, which lasts for a very short period of time.

The costs are absolutely horrendous.

Now, scientists will publish work, but if there's an economic consequence from that work, there'd be no responsibility.

they will get on and publish the next paper.

And then they publish the next paper.

So it's absolutely crippling Western countries who are going down this path because you cannot run an industrial economy on sea breezes and sunbeams.

There's just not enough grunt.

Well, I think you should tell your Prime Minister that you breathe in 0.04% carbon dioxide, and because he's metabolising food, he breathes out 4% carbon dioxide.

So if he wants to go to net zero, drop dead.

That's the solution.

It's totally ridiculous.

Our bodies are carbon-based.

Carbon dioxide is a major planetary gas.

It's been around for billions of years.

The first atmosphere had methane and hydrogen and helium and some carbon dioxide in it.

The second atmosphere, which was dominant for a very long period of time, was rich in carbon dioxide.

And it had hundreds of times more carbon dioxide than now.

And what do we see?

A thriving of life.

And the third atmosphere is an oxygen-bearing atmosphere, which we currently live in.
