"This whole idea of terraforming Mars, as respectful as I can be, are you guys high?"
Bill Nye says the idea of Mars colonization and terraforming – making a planet more Earth-like by modifying its atmosphere – is "science fiction.".
"We can't even take care of this planet where we live, and we're perfectly suited for it, let alone another planet.".
The famous science educator and CEO of The Planetary Society appears on National Geographic Channel's series "MARS."
While the series explores human beings living on the Red Planet and even mining it, that doesn't mean Nye buys into the idea.
"If we were to find evidence of life on Mars ... it would change the course of human history," he said. »
