Should Extinct Animals Stay Extinct? (Encore)
Summary
This episode debates whether scientists should use CRISPR and ancient DNA to de-extinct species like the woolly mammoth. Experts Ross McPhee and Lynn Rothschild argue against the practice, citing ecological risks, high costs, and the lack of a track record. Conversely, Stuart Brand and George Church support the effort, viewing it as a vital conservation tool that can restore ecosystems and combat climate change. The panel discusses the ethical implications, technical feasibility, and potential benefits of reviving extinct animals.
