is doomsday coming?

do you know the movie <2012 the end of world> ? it tells us a story about maya prediction that the world will end in 2012.is doomsday coming? will that happen in 2012 as the prediction tells us? though i don't whether it is true, after reviving phenomenons these years : SARS in 2003 and then H1N1 in 2009, snow crisis in the south and then in the north , colder and colder in winter but hotter and hotter in summer, more and more cars , more and more pollution......i am not sure if the pridiction come true in 2012. but i know the doomsday is coming because of what we human being have done rather than the prediction .
