Host: Fraser Cain ( @fcain )

Special Guest:  This week’s guest is NAT GEO’s Stephen Petranek. He is the author of How We’ll Live on Mars (TED Books.) Stephen became a reluctant doomsayer when his earliest TED Talk (10 Ways the World Could End) racked up 1.5 million views. But Petranek is, in fact, an optimist who believes that humanity will escape its predicaments — literally. Within a century, he predicts that humans will have established a city of 80,000 on Mars: and that not only is that plausible, but it’s also inevitable.
