Can, and should, we bring species back from extinction? Advances in biotechnology may enable us to revive the passenger pigeon, the great auk, and even the wooly mammoth -- and help restore biodiversity and genetic diversity in the process. But critics say that de-extinction efforts distract from important conservation priorities like combating habitat destruction and saving existing species. We discuss the issue.
