If not, how do we break out of the exponential growth that is happening
and will continue to happen?

We are due another ice age.

Yes.

That will have a huge impact on food production.

Nope, not anymore.

That will thin out the numbers somewhat.

Nope.

I don't believe you.

Doesn’t matter what you believe.

With ice approaching from both poles, the major food sources (American
prairies, Argentinian pampas, large areas of the EU) covered in permafrost
at least, if not a kilometre of ice, you are not going to grow enough in
the bits left unless there is a reduction in the mouths to feed.

Perfectly possible to grow food in the
same way the Netherlands does now.

You might in the short term, but not over thousands of years.

If it works in the short term, it
will work over thousands of years.

Plus the fact that much of the world's power generation capabilities will
be in the frozen bit.

Just build nukes instead.

That will cut production

Not when they are replaced by nukes.

and the number of greenhouses that can be heated.

Not when they are replaced by nukes.
