Nathan Hagens is a former hedge fund manager who shifted his attention to the study of fossil energy depletion and founded the website The Oil Drum. In this episode Nate and Eric talk about the turn of events that shifted his career and attention away from the finance sector and to the study and social context of energy, people’s resistance to stories about reduced consumption, fossil fuel depletion and stocks versus flows, human beings as a superorganism, and adaptive cycles, among other things.
