there may be something that happens like maybe the Yellowstone volcano will erupt.But there will be nothing that has to do with the end of the world.Yes the Mayan calender ends on that date ,but that doesn't mean that is when the world is going to end.I mean common people they could have been taken over by another colony before they could finish the calender.But we are not all going to die.We survived the ice age the end of the dinosaurs.there will be no tragedy that kills the human race.We have satellites that detects meteors and missiles to intercept them.well cant write anymore got to go bye.
