text: C'mon, Bozo, I've never advocated everyone moving to Texas.  I was just making the point to show that the Earth isn't over-populated.  We only have 10% of the population density of Europe's, but ours is quite a bit more dense that Russia's.  We have a lot of arid and semi-arid land that could be made productive if we ever decide it's worth the cost to bring desalinated water to it.  The Earth ain't running out of water any time soon.
