Book excerpt: With Marx and Nature , Paul Burkett reconstructs Marx's approach to nature, society, and environmental crisis. While recognizing that production is structured by historically developed relations among producers, Marx also insists that production as a social and material process is shaped and constrained by natural conditions, including the natural condition of human bodily existence. Marx's value analysis places him squarely in the camp of the growing number of ecological theorists questioning the ability of monetary and market-based calculations to adequately represent the natural conditions of human production and development.
