I guess there are some ethical considerations to changing the landscape of another planet — most of them were raised in Robinson's Mars Trilogy. But for stuff like metal- and mineral-rich asteroids and comets with water ice, I say bring on the strip-mining bots! I don't think we could realistically have colonies on the moon, Mars or further out if we have to tug every single bit of sustenance out of Earth's gravity.
