Aftermath: Population Zero (2008) watch online

Aftermath: Population Zero (also titled Aftermath: The World After Humans) is a Canadian special documentary film that premiered on Sunday, March 9, 2008 (at 8:00 PM ET/PT) on the National Geographic Channel. The program was produced by Cream Productions.

Aftermath depicts what scientists (and others) speculate the earth, animal life, and plant life might be like if humanity no longer existed, as well as the effect that humanity's disappearance would have on the artifacts of civilization.

Both documentaries are inspired by Alan Weisman's The World Without Us.

A four-part follow-up TV series called simply Aftermath was created, following what happens under different scenarios.
