Life After People: The Series is a documentary television series that began premiering on April 21, 2009 on the History Channel. The program is a spin-off of the documentary film Life After People. The series features material not previously mentioned in the original documentary film.
History channel announced that Life After People: The Series would return for a second season in January, 2010.
The series shares the same tagline as original documentary film: "Welcome to Earth...Population: Zero."
With an audience of 5.4 million viewers, the original documentary film was the most watched program ever on the History Channel. Aftermath: Population Zero, a program with a similar premise, aired on the National Geographic Channel in March 2008.
In the program, scientists and other experts speculate about what the Earth, animal life, and plant life might be like if, suddenly, humanity no longer exists, as well as the effect humanity's disappearance might have on the artificial aspects of civilization. Speculation is based upon documented results of the sudden removal of humans from a geographical area and the possible results that would occur if humanity discontinues its maintenance of buildings and urban infrastructure.
The series features the gradual and post-apocalyptic disintegration of urban civilization in a time span of 10,000 years after humanity suddenly vanished. The hypotheses are depicted using CGI dramatizations of the possible fate of iconic structures and landmarks (e.g., The Pyramids, the Empire State Building, the Sears Tower, the Space Needle, the Eiffel Tower, the Golden Gate Bridge, and the Hoover Dam).
Life After People does not speculate about the cause or manner of humanity's sudden disappearance.
