Rev. Blackmouth,

You make an interesting point about ideas. While ideas may be infinite, I wonder if you think the same about the number of people this planet can support, and if the creativity and resource that is mankind can muster the resources to support them. I saw on TV once (I know, highly reliable information source) that there aren't too many people in the world, and as proof, the program narrator pointed out that all 7 billion of us, standing shoulder to shoulder, could easy fit in the state of Texas, with room to spare. Of course, even a half wit, and maybe most Republicans, knows that 7 billion people couldn't actually live in Texas. And many know that much of the world's land surface is not inhabitable. Hell, some of us pragmatists think arid regions like Phoenix, LA, and Las Vegas, to name a few, are already over-populated, given the lack of water. Turn off the long pipe spigots and they die.

So what assumptions do you agree with? Is there a finite number of people this planet can support? And if so, about how many do you think that would be?
