I understand your concern, but there is a fundamental, pretty dangerous flaw in your reasoning, here, I think.

The idea that population needs to be somehow reduced is itself potentially fatal for the species, I would say.

That is what is currently on the cards, with the buildup currently to a world war.

It is also at the heart of Nazism, which is just the disregard for human life that you mention, focussed towards those we might become convinced are less valuable than ourselves, it seems to me.

In terms of energy, the problem is that throughout our history to date, we have actually destroyed, more than created.

That was the only mode possible, before we started accepting energy from the sun.

Now, what folk seem to be having trouble with, is understanding that by using the energy of the sun, we can reverse most of the destruction we did before now, by using the energy of the sun, to start truly creating.

Everyone working from the sun will automatically be creating, just like nature creates, no longer destroying.

So the more hands to the pump, the better.

A cull of any kind now, could actually jeopardise our capability to put things right.

On the other hand, if we do the cull, whilst obviously worsening the envionmental problem, since the cull itself will be fossil or nuclear fueled, we break the camel's back, it seems to me.

This is why I argue the energy from the sun has to be monetised.

That is the only way we are going to correctly value it.

Money-as-debt doesn't do it, because for money as debt, something always has to be given in return for it.

Whilst nobody is demanding anything in return for the Joules we receive from the sun, other than we correctly value it. So the money representing it has to be for free, issued to all people.

With all government, and all communities solar powered, backed up by hydrogen to remove the need for batteries, as could quickly be achieved, if the money representing product already created since around 2005 was issued as instant stimulus, we could do this in only a year or two.

Quite a different scenario from a cull, wouldn't you agree?

If we had such a cull, we may never know the future we could have had, if we never got hooked on profit.
