I highly doubt 2012 will be the end of the world. 2000 was supposed to be the end of the world and we all know that turned out to be nothing.
The end of the world is pure nonsense. But when that date comes with no event, a new doomsday will be made up.
Doomsday was created by religious zealots back in the Dark Ages of around 1000 years ago. Society on this planet have become more educated and progressed significantly over the time and few people believe in Doomsday psychobable.
The December 21 2012 date is just the last date of the Mayan Calendar.
