(Some) Extinction Is (Not Necessarily) Forever: Video of My TEDx talk

What would it take to bring back an extinct turtle, or a long-gone mammoth? Thanks to the folks at TED for posting the video of my talk about my story in the April issue of National Geographic, embedded below.

(TEDxDeExtinction will be posting the videos of the rest of the talks from the meeting over the course of the next few weeks.)
