Episode Detail: Last Days on Earth - 20/20

Elizabeth Vargas explores seven scenarios for cataclysms that could wipe out civilization on Earth, assesses the likelihood that any of them could occur and looks at ways humans might be able to stop them. They include: a gamma-ray burst caused by the “death” of a star; artificial intelligence running amok; the eruption of a supervolcano; an asteroid strike; nuclear war; a pandemic or bioterrorism; and climate change.
