There is nothing reasonable about moving to Mars - a place where the average temperature is -55C and there is no breathable atmosphere. Imagine such a place on earth, and now imagine trying to sell a home there to someone. We may, one day, colonize other planets. But we evolved specifically to exist on this one. Each new environment will likely take centuries, if not millenia, to properly colonize. The fact that it is theoretically possible for a comically tiny fraction of Earth's population to eke out a hardscrabble, miserable life on other planets should not impact policy decisions on terra firma.
