"Not to put too fine a point on it, I never heard so much fucking nonsense in my life. There’s absolutely nothing that might make Mars a “sustainable” habitat for human beings, or probably any other form of Earthly life. The journey alone would destroy human bodies. If you think that living in Honolulu is expensive, with most daily needs of the population shipped or flown in, imagine what it would be like sending a cargo of provisions (Doritos? Pepperoni sticks? Mountain Dew? Fabreeze?) to a million “consumers” up on Mars. Or do you suppose the colonists will “print” their food, water, and other necessities?"
