The Global Catastrophic Risk of a Human Will and Destructiveness

A global catastrophic risk of a human will and destructiveness is just exactly as it sounds. Someone decides, either intended or unintended, to pursue a set of actions that result in the consequencef of game over. It's quite possible now to imagine a terrorists getting their hands on some kind of technology which could destroy modern civilization beyond its ever being repaired. But conventional political terrorists are not something to worry about because they actually have concrete goals. They want to achieve a particular political end. What is more serious is the threat of an eco terrorist who thinks that human beings are a plague on the planet and need be wiped out.
