Interesting theory.
Like most modern countries, the birth rate is slowing down while the death rate is as well.
In parts of Europe, some countries are close to actually losing population.
As for world population projections, it doesn't look like anymore we will see the great overpopulation feared in the 70s, 80s, and even 90s.
Seems to be a natural trend in more developed countries for birth rates to drop. Probably because the chances of raising a child to adulthood increase, and because there is less need to have lots of kids for little plowhorses.
It seems like we have a tendancy though, when famine sets in, to make the problem worse by kickin out lots of kids. I suspect the first reason I gave accounts for that more than anything.
Yes, but its ironic that the anti capitalists like Paul Erlich have been replaced by 'show me the money' laissez fair types who claim the US needs continued massive immigration or our economy will collapse. Buncha hysterical Cassandras.
