Neil deGrasse Tyson and panelists discuss de-extinction in the 2017 Isaac Asimov Memorial Debate at the American Museum of Natural History. Biologists today have the knowledge, the tools, and the ability to influence the evolution of life on Earth. Do we have an obligation to bring back species that human activities may have rendered extinct? Does the technology exist to do so? Join Tyson and the panel for a lively debate about the merits and shortcomings of this provocative idea.
