I find it to be a certainly risible level of hubris to think that the very species which has mucked it up (well, supposedly), through the same motivating factors as those which motivate the current drive to explore space (read: profit -- altruism in the main players is a myth), shall accomplish a different result (if the present's result is to truly be believed as anthropomorphic).
Your desire to forge forward into the last bastion of stuff we can f' up on our own planet doesn't follow circular logic.
