Before we ever reach the point of sending a generation ship out to the stars, we will likely already have spent a good deal of time learning how to build and maintain artificial environments in the form of orbital space colonies in our own system.  This is turn means we will already have populations more attuned to this type of life.  It will be these people that crew these generation ships.

Indeed, but my point is, however pure the seeds for a new world, the old world is still in there...

And the old world could kill a planet.
