Life After People is a television series on which scientists, mechanical engineers, and other experts speculate about what might become of planet Earth if humanity suddenly disappeared.

The program does not speculate on how humanity may disappear, stipulating only that it has, and that it has done so suddenly, leaving everything behind including household pets and livestock that have to fend for themselves.

The thought experiment is based on documented results of the sudden removal of humans from a geographical area and thus, the discontinuation of the maintenance of buildings and urban infrastructure.

The focus is on specific locations such as skyscrapers, religious icons, bridges and dams, and government buildings, and the fate of certain related objects, such as artifacts, documents and human bodies.

The timeline of predicted events begins approximately one day after the disappearance of humankind and extends at various intervals up to one hundred million years into the future.
