Apocalyptic and post-apocalyptic fiction

Apocalyptic and post-apocalyptic fiction are subgenres of science fiction in which the Earth's (or another place's) civilization is collapsing or has collapsed. The apocalypse event may be climatic, such as runaway climate change; astronomical, an impact event; destructive, nuclear holocaust or resource depletion; medical, a pandemic, whether natural or human-caused; end time, such as the Last Judgment, Second Coming or Ragnarök; or any other scenario in which the outcome is apocalyptic, such as a zombie apocalypse, AI takeover, technological singularity, dysgenics/eugenics, natural disasters, or alien invasions.
