[monkeyman40210]

Nuclear War, One country will miss fire weapons through false intelligence and or electronics malfunction, which will cause a retaliation and so on.

Runner Ups:

• 
  Bi-Terrorism
• Asteroid
• Burning of the Earth
  • as "ManusJustus" said, the Sun Expanding at the end of it's life cycle, and burning the Earth, eradicating humans from existence is the way that we shall go if none of the above succeed in doing so... 

There are my four ways that I see the "Apocalypse Scenario".
