"Green Lantern, these are the plans for creating water, could you willpower up a thousand factories. Superman, Wonder Woman, there must be some sort of Kryptonian or Paradise Island technology that would help. And while you're thinking about it, could you find a planet that has water and bring back a few icebergs worth, just to tide us over? And could one of you that can travel back in time fix it so we started building these factories a decade ago?"
