Is 2012 the end of the world as we know it? From 2012 to global warming to worldwide epidemics, our society's fascination with doomsday is as strong as ever. Do any of these apocalyptic scenarios pose a real risk? Why does our modern culture embrace these bleak beliefs? Divorcing hype from truth, J. Allan Danelek scrutinizes the ancient Mayans' 2012 end date, in addition to a wide array of doomsday beliefs from biblical prophesies to biological warfare. With piercing logic, he objectively explores each apocalyptic threat ...and reveals startling insights of what kind of future - dire or dazzling - awaits humanity. An avid reader and careful investigator, Danelek enjoys presenting alternative theories on increasingly popular subjects dealing with the strange and inexplicable world around us.
