Neither the fall in birth rates nor its rise is intentional. I struggle to understand why people think a mega fauna of 7-8 billion people takes intentional decisions. An individual takes intentional decisions. Humanity … not so much I think.

Correct, but my point is unless we find a way to intentionally fix the problem we're going to unintentionally walk into a disaster.

I don't fault your logic, but I don't want to accept that disaster is inevitable.
