The awareness that happenings of the future cannot be determined with certainty must have arrived quite early to prehistoric man. However, completely grasping the notion of risk remains an ongoing process. The reason for this is over the millennia, and especially in the past few centuries, we have created an increasingly complex and interdependent habitat. Man no longer fends for himself and his small family unit by growing food and building shelter. Instead we depend on people and their eorts across the globe for every single and simplest of our needs. Therefore the happenings of the future at far and wide locations of the globe that cannot be determined with certainty hold the potential of aecting our happiness, well-being, and even subsistence.
