Ma Yuanjiang survived eight days trapped under the rubble of an earthquake in China. He had no food or water, so he ate paper and drank his own urine. Ma had no training in survival. He was a business executive, yet somehow, against all odds, he survived longer than almost anyone else who has ever been trapped. How could this be? Movies and books often depict survivors as tough, confident guys, who know everything. But what about in real life? Who is most likely to survive a disaster?
How close are we to doomsday – the destruction of the planet and the end of life as we know it? The Doomsday Clock is a symbolic way to answer this question. In 1947, a group of scientists who had worked on the world’s first atomic bomb started tracking how close the world is to doomsday. They marked the end of the world at midnight on their metaphorical Doomsday Clock. The clock is adjusted yearly according to political instability and environmental dangers that threaten the safety of the world.
