Banjo,
Previous human experience was that famine was caused by wx such as
droughts. These are normally short term, say one to 12 years, but what
we will see is an energy, and fertiliser, caused famine for which there
may be no solution and it will be permanent.

That changes everything and there is no previous human experience.
It will of course be tied to the "End of Growth".

It is a silly question to pose as it implies that the human population can only be determined by an executive decision. The current population growth is determined that way, because the elite in many countries deny their citizens access to birth control. Were such access available, the worlds population would be stable or in decline.

A better question to pose would be "Should the worlds population be determined by a few or by the free choice of everyone who is fertile?".

one minute its obesity and the next its overpopulation. Now that the gw scam has been exposed we need a new scare for the marxist to take the money off the masses.

"Should the worlds population be determined by a few or by the free choice of everyone who is fertile?".
Fester,
I'm inclined to let those who can feed their families have the choice.

runner,

"one minute its obesity and the next its overpopulation..."

Sometimes it's both simultaneously....

It is none of those I told you, it is energy to produce food.
