"Extinction is a different kind of death - it is bigger..."
This TEDTalks is all about recreating extinct species and even ecosystems. Stewart Brand talks about people like Ben Novak, a young scientist pioneering "de-extinction." He is attempting to bring back the Passenger pigeon with the use of ancient DNA found in the bird's toe pad (only one of these birds remain on the earth today). Why are these mammals disappearing? What possibilities arise from the employment of "de-extinction?"
In between handfuls of popcorn, consider the following questions:
Could this kind of scientific experiment interrupt the delicate balance of predator and prey?
Do scientists run the risk of compromising an ecosystem by reintroducing weaker species?
Is extinction a bad thing when a species can no longer naturally survive without artificial support?
