This seems to be an incredibly short-sighted point of view for someone who buries himself in the mantle of Science. I wonder if his recent delvings into social justice have NPC-ified him?

Bill Nye says Mars colonies won’t happen: ‘Are you guys high?’

“This whole idea of terraforming Mars, as respectful as I can be, are you guys high? … We can’t even take care of this planet where we live, and we’re perfectly suited for it, let alone another planet.  … Nobody’s gonna go settle on Mars to raise a family and have generations of Martians … It’s not reasonable because it’s so cold. And there is hardly any water. There’s absolutely no food, and the big thing, I just remind these guys, there’s nothing to breathe.”

Meh. Translation: “It’s hard so nobody will want to do it.”
