I remember something I read from the 1970s which suggested that the Earth’s carrying capacity was about 2.1 billion. That number of humans could be sustained indefinitely. Going higher than that would result in environmental degradation that would reduce the carrying capacity. We are now at that point and the population will go higher in spite of the the low birth rates. Every day we diminish the environment and de-terraform the Earth. I am fine with the population declining naturally over time. I wish the Western countries could do more to absorb additional immigrants. This would have a positive effect for their own aging demographics but also worldwide as money flows to home countries. I will probably die about the time population reaches the peak. I have always felt that that peak will be a difficult time because of poverty and demographics. Nothing we are doing now is preparing well for that time.
