Jane Poynter tells her story of living two years and 20 minutes in Biosphere 2 — an experience that provoked her to explore how we might sustain life in the harshest of environments. This is the first TEDTalk drawn from an independently organized TEDx event, TEDxUSC, held at the University of Southern California. (Recorded at TEDxUSC, March 2009, in Pasadena, California. Duration: 15:54)
