A, I guess I will just call it a good thing, a good thing about the population growth is that the bulk of it will occur in regions where each new person does not add much of a load on the environment. It's much different to have a new person be born in an area where the average resource consumption per capita is low, than to have a bunch of new heavy consumers in places like the US or EU. Can you imagine what would happen if those 12 billion all loved burning fossil fuels and eating beef as much as Americans? Lol.

A return to sensible farming would be a nice area of personal growth with real impact on the world, that sounds like a cool career choice.
