Editing Doomsday event

A '''doomsday event''' is a specific occurrence which has an exceptionally destructive effect on the human race. The final outcomes of doomsday events may range from a major disruption of human civilization, to the extinction of human life, to the destruction of the planet Earth, to the annihilation of the entire universe.

A [[2006]] poll by SciFi.com revealed that virtually all [[United States|Americans]] believed that some sort of doomsday scenario is just around the corner and could realistically impact the human race, and that many feel that such a scenario is likely to be man-made.
