A great lecture by Professor Al Bartlett on exponential function:
Part2 of the lecture explains the cunundrum we find ourselves in. What we consider as “good” is mathematically bad, and what we consider as “bad, is mathematically good for a stable population with zero fertility rate. He explains that if we do not voluntarily make some hard decisions now, nature will do the job for us eventually in very drastic ways.
One thing is abundantly clear, “go forth and multiply” is NOT a command of god, it leads to death.
