I feel the same way about projects looking into habitation of foreign planets. The science and the engineering behind the endeavor is interesting, but why seriously not start thinking about and practicing sustainability in places like Antarctica?

Colonizing another planet is a hedge against a destructive event (asteroid, bomb, etc) completely extinguishing the human species.

Colonizing another planet would be a speciating event. Alpha Centurians would become a different species anyway, just like a population of birds that gets stranded on a remote island becomes a different species.
