This is extremely interesting to me since I have recently (in the last year?) read that global population has hit a plateau and will not continue to rise. That did not make sense to me, at the time. But now seeing these explanations it is rather convincing. At least I am more inclined to agree.
So unless life spans increase very significantly we may have hit “peak people”.
Not so. It's like the difference between the federal deficit and the federal debt - birth rate is no longer increasing, but population will continue to grow until the death rate catches up to the birth rate.
