  Its highly unlikely humans will end the world – the world has existed long before we evolved. Unless we develop a Death Star, only a natural disaster (asteroid bomboardment, super volcanic eruption, Sun going nova) could wipe out all life on Earth

  Our actions as humans are destroying small parts of planet earth but I don’t think we will end the earth by our actions. I do think that the earth will one day cease to exist but that is a long, long way off!

  I think it is unlikely humans will cause the world to end. Despite conflict and turmoil at the end of the day there is a higher drive in humans to prolong life so it is unlikely our actions alone will wipe us out as a species.
  
  It is more likely that the destruction of the world will be external circumastance – the Sun exploding, Asteroids, a massive natural disaster etc.
  
  Or you know… Aliens 😛
