Ah, those crazy old end of the world prophecies... that were predicted by frauds or people who just wanted attention. And what's this junk about the Mayan calendar ending in 2012? Here's a question for you all: what happens at the end of our modern calendar, on December 31st? It goes right back to the beginning again. So the Mayans thought they'd be around for a while, or something. But the end of a calendar as "end of the world" is just plain silly.
As for the world being destroyed, well, it takes a lot to destroy a planet. Human civilization, sure, that could happen any number of possible ways, whether it be by nuclear holocaust, continent-affecting plagues, drastic food and fresh water loss, sea levels eventually rising high enough to cover livable land masses, or a comet or meteor slamming into the earth at high velocity causing mass extinctions. Now, considering that none of those occur, I refuse to believe that the world will end by any kind of acts of divinity. For that matter, destroying an entire planet full of life, human and non-human alike is NOT divine, it's just a crap deal, folks. And are there really THAT MANY people dissatisfied with life on earth that they really, really want civilization to end? That's extraordinarily selfish and/or stupid. Not that humans, as a general rule, are capable about thinking of that many others besides themselves, so there you go. And... I think that's the end of my spiel. Make of it what you will.
