Unintentional "Dark Futurist", Stephen Petranek, revisits the subject matter of his original eleven year old TED Talk and offers the audience an extraordinarily sobering look at the eight critical issues that threaten human life on Earth.

In the spirit of ideas worth spreading, TEDx is a program of local, selforganized events that bring people together to share a TEDlike experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, selforganized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are selforganized.* (*Subject to certain rules and regulations)
