DESCRIPTION:How will humanity go extinct? Is it more likely to be from nat
 ural causes such as an asteroid impact or anthropogenic causes such as a n
 uclear war? Using the fossil record\, we can place a rough upper bound on 
 the probability of human extinction from natural causes: all natural cause
 s put together have less than a 1% chance of causing human extinction each
  century\, and probably less than 0.1%. In contrast\, it is very difficult
  to put upper or lower bounds on the chance of extinction from anthropogen
 ic causes.\n\nIn this talk\, Dr Toby Ord advance an argument that anthropo
 genic causes currently produce ten or more times as much extinction risk a
 s the natural causes\, and shows how this suggests that we should prioriti
 se the reduction of anthropogenic extinction risks over natural ones.
