I used to live in a country that had a program to get social groups to step in when friends get to child number five. If you’re poor and disadvantaged the next child is just idiocy.
The bulk of the overpopulation comes from communities with no way to stop a population boom.
But, the environmental footprint from rich Western country parents is equally nuts.
As long as you are neither problem, you’re probably going to have a child that is part of the solution.
I live in my headphones. If anyone chatty is around I put headphones on as an indicator of concentration. (Not that it works)
