The population is on track within a few years to double since I was born, regardless of what happens in Asia and the West. For example, fertility rates in just Africa are up to 6.8 in some countries, with just them producing more new humans than the entire world did, say, 70 or so years ago. Within a couple decades or so, just Nigeria will have more humans in it than the entire US at current rates. So no, I'm not worried about overall population decline.

I do wish it were true though. I've lived out in the countryside most of my life, and have seen it get utterly destroyed for more houses, strip malls, warehouses, and other sprawl. The natural world has really taken one for the team to make room for all the people we already have.
