"People in their 20's will see peak world population in their lifetime. It will be fascinating to see how society changes over the decades that follow that."

I am 45. I have fairly big* chance of making the global population curve actually drop!

*OK, not really, but you get the point I hope....

All projections show world population growth until at least 2100, thanks to Africa birth rate above 4.

No, they don't. That's the UN prediction, because they assume that somehow, magically, all countries below replacement will simultaneously, near-instantly increase in fertility rate by huge amounts over the next couple of years. Look at the graphs, they're nonsensical.

If you look at the actual trends of those rates, peak population is ~2050, maybe sooner.
