I wasn't bored or anything last year but I made a spreadsheet of the world population and the higest rise in world population occurred in the 1960s at 2% per year world average. The the world population has been rising but the rate of change has been dropping. We are down to 1% per year. Should we extrapolate, this should get close to zero in fifty years and perhaps go negative for a time. We should get to a equilibrium somewhere under 20 billion if we trust the extrapolation.

Humans live longer! Now what?
Interesting! When looking at Worldometers they also had the growth percentage graph! It's very interesting to visually look at how the growth is slowing down!
And for people who only now started looking at statistics because of COVID, then the world's population graph will feel very familiar!
Exponential growth, then exponential decline!
Also, 20billion!?, I think an updated projection puts as at 11 billion at most!

I don't know how they project the population growth but I am not so confident in my number. It may be right that 11 billion is the equilibrium projected based on previous numbers but conditions are changing.
I do think climate change is real and climate change could make parts of Canada and Asia habitable and other parts more habitable than today. The added carbondioxide has been and I think will continue to make the Earth greener and food production more productive. This rise of photosynthesis might be so high that the carbondioxide. Plants grow best with much higher trace amounts of carbondioxide than we have today.
This could all go sideways though if enough people become infertile from the Covid shots. Also, climate change could go the other direction and force an ugly and sudden depopulation. Then there is diseases, war, a skynet and a grey goo scenario.
