So the population goes from 7.7 billion to 7 billion, then to 6 billion, then 5, 4, 3, 2, 1 billion, then 500 million, then 50 million, then 5 million, and in the hundreds or thousands of years that takes (if negative fertility rate is the main cause) you don't think this trend will change? Why not?
We've had a positive fertility rate for 200,000 years (we could even be super conservative and say 30,000 years) and you think the current ~70-year downturn is the
real trend.
