Amen to that. We could figure out a way to make the deserts much more inhabitable. Anyone visit North Dakota? Hardly anything but farmland there. There is also the fact that 2/3 of the earth isn't even built upon...the oceans. Build underwater, or on top. And the Japanese have an idea to start building down, into the ground. I don't see any REAL PRACTICAL reasons to colonize mars
