Doomsday scenarios are possible events that could cause human extinction or the destruction of all or most life on Earth (a "true" or "major" Armageddon scenario), or alternatively a "lesser" Armageddon scenario in which the cultural, technological, environmental or social world is so greatly altered it could be considered like a different world.
