About Terraforming... (Score 3, Insightful)

If we could terraform Mars, do you really think it would be hospitable? There's more to Earth than water and oxygen that makes it possible for life to live here. The moon, for instance, is just in the right position to affect our tides so they aren't out of control. And the magnetic field that helps move that nasty radiation around us... I wonder what it would mean for Earth if we terraformed Mars, changed it's magnetic field. It might even effect life here. I say we leave Mars alone before we kill ourselves.
