Abstract
This article argues that a main hidden driver of the Anthropocene is existential—namely the wholesale denial, in capitalist civilization, of human fragility and mortality. Mainstream economics, which unthinkingly validates the unboundedness of human wants and the necessity for open-ended growth, must give way to existential ecological economics—an approach that recognizes that capitalism, which clearly propels the overshoot of material flows, is itself a device for denying and repressing deep human fears about death.
