A former nuclear weapons designer, Stephen M. Younger understands, as few others can, humankind's potential for violence. He knows that the proliferation of weapons of mass destruction means that any nation, group, or even individual could cause unimaginable carnage--and the accelerating pace of communications and transportation means that things can happen faster than we can think about them.

In Endangered Species, Younger peers into the heart of modern civilization to present a practical plan for ending mass violence, the scourge of our times and a threat to our survival as a species. Looking across our knowledge of psychology, history, politics, and technology, Younger presents a convincing argument that we can escape our spiral into global destruction. But we haven't a moment to lose.
