Colonizing Mars will cost around a quadrillion dollars. The reason Musk and Bezos want to leave is that the think the planet is ecologically doomed. But for a fraction of the cost of colonizing Mars, we could save the Earth - and then we'd have all the time we liked to engage in space travel.

Why do people want to allow the Earth to die, and colonize the cold, dark, poisonous, radioactive, airless, arid lifeless deserts of Mars? I believe it springs from a profound hatred of life itself.
