The proposition that we now live on a radically transformed and damaged planet is uncomfortable and troubling. It suggests a dangerous rupture in the earth’s trajectory that calls for new ways of thinking about safety, protection and collective survival. For many the Anthropocene marks an existential moment for modern civilization that radically unsettles the nature/culture divide that under pins much of Western philosophy, science and politics. Faced with the devastating effects of melting Arctic ice sheets, loss of critical habitats and mass species extinction, the idea that we can secure humanity against external threats is precisely the problem that needs to be overcome. In a time when our global modes of economy, trade and consumption are disrupting the planet’s lifeupholding systems, dualistic understandings of an active and morally countable human subject and a passive and external nature no longer seem to make analytical or moral sense. The distinction between humans and their surrounding environment, so central to the environmental policy and security paradigm, is replaced with a more fragile and entangled universe that binds human and nonhuman worlds together in complex and unpredictable ways.
