I don't take umbrage with Ham's idea that there might not be population overgrowth, but with the fact that he came out of nowhere and called Alex a Nazi just for suggesting that there's too much breeding going on (which, if there's population overgrowth, THERE IS).
Also, Stuu, that's not the first time I've heard the Texas theory but I can't remember where it was I heard it before.
Actually, I never called anyone a nazi. Nazis were not the only proponents of eugenics. Within the progressive movement you'll find many individuals who have argued for eugenics. I'm simply stating that claims of unsustainable population growth have been made in the past, many times. The world's population has continued to grow, and yet we're still sustaining the current population. It's my view that we'll continue to sustain growth of population in the future.
Part of the problem is that many people who make claims about the sustainability of population size use modeling of population growth that is far too simplistic. They take current (for the period) food production levels and extrapolate from there, ignoring the human race's incredible ability to increase efficiency of production through technological and scientific breakthroughs.
If you don't want to argue this via food availability, but rather, energy or something along those lines, I maintain that new technologies will have just as strong an impact in these areas. When they started drilling for oil, I'm sure there were all kinds of oil deposits that were beyond their ability to access. Yet advances in technology have opened up new sources. Deep sea, oil shale and the like. I could make the argument that oil will eventually run out. But who's to say that 100 to 150 years from now we won't have the technology to take organic waste matter and transoform it into crude? It's silly to try to model something like this so far out into the future simply because the human race makes such amazing strides in sceince and technology that we really can't predict what life will be like at that time.
That is all.
