Jairus Victor Grove contends that we live in a world made by war. In Savage Ecology he offers an ecological theory of geopolitics that argues that contemporary global crises are better understood when considered within the larger history of international politics. Infusing international relations with the theoretical interventions of fields ranging from new materialism to political theory, Grove shows how political violence is the principal force behind climate change, mass extinction, slavery, genocide, extractive capitalism, and other catastrophes. Grove analyzes a variety of subjects--from improvised explosive devices and drones to artificial intelligence and brain science--to outline how geopolitics is the violent pursuit of a way of living that comes at the expense of others. Pointing out that much of the damage being done to the earth and its inhabitants stems from colonialism, Grove suggests that the Anthropocene may be better described by the term Eurocene. The key to changing the planet's trajectory, Grove proposes, begins by acknowledging both the earth-shaping force of geopolitical violence and the demands apocalypses make for fashioning new ways of living.
