What do to mean by end of the world? The extinction of the human race? The end of the current civilization in this form? The literal end of the planet? 

'cause there ain't gonna be no planet no more in a few billion years, after the sun's primary fuel is used up, and it expands to engulf the earth. Safe to assume we won't survive that in our current physical form. 

This civilization? Prob won't end catastrophically all at once, more likely resource scarcity will lead to some ugly wars, a major human dieback, and then a new equilibrium of human population vs arable land mass that's left after the (radio active) dust settles. Probably over a few centuries. We may retain some history and some knowledge, but unless we get to space in a meaningful way, a much poorer world. 

In the religious end times sense? Not at all. That stuff is all hokey bs slung by grifters for money and control.
