I guess we'd need to define end of the world? Does that mean end of humanity, or end of civilization as we know it?
To knock off the species, I suppose an epidemic or an asteroid strike could do for us.
Knocking down civilization is a lot easier. We've built up an artificially high population using cheap energy and all the technological advances that cascade down from it. Take away the cheap energy and we'd have a pretty nasty depopulation event most places.
A serious ecological collapse could be just as dangerous as anything else, even if people's ideologies won't allow them to deal with the idea to begin with.
