It is a matter of order. First, we learn how to terraform ourselves out of our inadvertent unhelpful terraflopping, then we use that learning to terraform anywhere we go. :)
Each day, we're given the choice to change the way we relate to the resources at our disposal. I haven't seen any evidence that the incentives which drive us to cause great harm have gone away. On the contrary, the evidence I have seen points to those destructive incentives as being the driving force behind space colonization.
