The Bulletin of Atomic Scientists was founded by some of the people who worked on the Manhattan Project. The clock was created at seven minutes to midnight. During years, this special “left time” oscillated. Now, it’s at three minutes. In other words, the survival of the human species is to be discussed. Wars around the world, creation of nuclear weapons, the limitation of such arms and again nuclear tests, the election of some important Presidents influenced all the time the “Doomsday Clock”. Now is speaking of the nuclear weapons modernization, the climate change and the continued existence of the nuclear weapons arsenals. How smart will be the humans to preserve the life on Earth ?
