In The Ecocentrists, Keith Mako Woodhouse offers a nuanced history of radical environmental thought and action in the late-twentieth-century United States. Focusing especially on the group Earth First!, Woodhouse explores how radical environmentalism responded to both postwar affluence and a growing sense of material limits. While radicals challenged the material and philosophical basis of industrial civilization, they glossed over the ways economic inequality and social difference defined people's different relationships to the nonhuman world. Woodhouse discusses how such views increasingly set Earth First! at odds with movements focused on social justice and considers the implications of ecocentrism's sweeping critique of human society for the future of environmental protection. A groundbreaking intellectual history of environmental politics in the United States, The Ecocentrists is a timely study that makes a case for the role of skepticism and doubt in environmental thought
