Yes, but going from positive birth rates to negative could also have a catastrophic effect on human civilization and send us back to a darkage just when we were supposed to tackle global warming.

Maybe it won't be that bad, I've never ran the numbers, but intuition tells me population reduction has never been good for human civilisation.

Interesting. I am not agreeing or disagreeing with your statement.

However, it only seems different from a moralist perspective. Naturally, the result is the same: a species reaches its carrying capacity and the population declines.

Fascinating.
