Nuclear war is an often-predicted cause of the extinction of mankind.[1]
Human extinction 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), for example by sub-replacement fertility.
Some of the many possible contributors to anthropogenic hazard are climate change, global nuclear annihilation, biological warfare, weapons of mass destruction, and ecological collapse. Other scenarios center on emerging technologies, such as advanced artificial intelligence, biotechnology, or self-replicating nanobots.
The scientific consensus is that there is a relatively low risk of near-term human extinction due to natural causes.[2][3] The likelihood of human extinction through mankind's own activities, however, is a current area of research and debate.
