Political Ecosystems is an unusual and highly original appeal to left-progressives and environmentalists and those sympathetic to those movements. It urges them to engage in more thorough self-examination, to assess more realistically their strengths, weaknesses and blind spots, and to learn to look at the darkened American political panorama through a variety of far more sophisticated lenses, and with a broader, longer, more nuanced view of history, culture and social change. A modest yet deeply informed account of the current state of eco and social justice activism and its adherents, Harpignies invites us to engage in a rigorous, but entertaining, and ideally rejuvenating, set of ideological calisthenics.
