End of Days?

As the year 2009 draws to a close, I've been finally catching up on some movies I'd missed and it all seems to tell of civilisation coming to an end with humanity desperately fighting to retain whatever we can salvage.

I've just watched Day After Tomorrow and 2012 in succession. I know, I'm REALLY slow to catch all these movies and I'd just found time after completing the Northern Touge Race Day and before starting to plan for the next event.

It's kinda sad to think that it'll all end with nature taking its toll after all humanity has been draining nature's resources at an extremely alarming rate of consumption. These events mentioned in the movies are somewhat affable if not grim to ponder, but do you think that we'll one day face extinction and will all of humanity's knowledge and technology be able to save us from the impending doom that will be cast upon us?

Or will we be claimed by the Dark Lord, no... not Voldemort, Beelzebub! From a religious standpoint, and from Arnold's (The Governator) movie End of Days, the Lord of Darkness himself will rise and wreak havoc on earth and all humanity for the sins we've committed.

How do you think it'll all end and what do you think we'll be able to do about it? Will we be claimed by nature in a torrent of molten rock and a wall of oceans bearing down on civilisation or will Beelzebub himself be summoned to (literally) raise hell on humanity?
What do you think?
