Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction or omnicide is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid impact or large-scale volcanism, or via anthropogenic destruction (self-extinction).

Based on oxygen's half-life in the atmosphere, animal life would last at most 100 million years after the loss of higher plants. [12] Some cyanobacteria and phytoplankton could outlive plants due to their tolerance for carbon dioxide levels as low as 1 ppm, and may survive for around the same time as animals before carbon dioxide becomes too ...

In the 2017 episode "The Pyramid at the End of the World", the Monks changed every clock in the world to three minutes to midnight as a warning about what will happen if humanity does not accept their help. Representatives of the three most powerful armies on Earth agreed not to fight each other, believing a potential war is the catastrophe.
Mass extinctions are characterized by the loss of at least 75% of species within a geologically short period of time (i.e., less than 2 million years). [18] [51] The Holocene extinction is also known as the "sixth extinction", as it is possibly the sixth mass extinction event, after the Ordovician–Silurian extinction events, the Late Devonian extinction, the Permian–Triassic extinction ...
