Our carbon-based societies may have achieved unprecedented levels of health and development, but the unintended consequences are dire. Our dynamic and volatile world demands that we challenge our understandings of ourselves, of the environment, and of security. This talk will explore these themes and take up the task of re-imagining security disciplines for the Anthropocene - the age of the human.
