Wow, there was actually a reaction to yesterday's blog post. Craziness.
Like I said yesterday, the inevitable population drop worries me more than it should. It is almost certainly decades away at this point. Still, I cannot shake the dread that humanity is going to do a poor job with the population drop, just like it has done a poor job with the population explosion of the 1900's.
For those of you who are interested in population drops, keep an eye on Japan in the future. Their population is currently dropping at a slow rate, which is expected to increase as time goes on. Not helping the situation is the fact that Japan's birth rate is at a record low.
So here's a question. Is the population going to eventually level itself out? In the future, will there ever be a situation where the number of deaths per year is exactly equal to the number of births per year? Alternately, will we ever have a fertility rate that is the ideal 2 children per every woman? (That's the ideal, because it gives you one child to replace the father and one child to replace the mother.)
