On Friday I published a post entitled, Sustainability: Cows, Sage Grouses, and Grasslands. It included reference to a newly released environmental documentary, Cowspiracy: The Sustainability Secret and two video interviews, one with Jeff Goebel and another with Allan Savory. Jeff wrote me back and emphasized the relationship of cows and grasslands to the central issue he sees as "to pull carbon and water vapor back to the soils of our earth." Cowspiracy, like other documentaries such as Meatrix and the Lie We Tell Ourselves or Back to the Start sponsored by Chipotle drive home the costs of corporate farming to Mother Earth, her ecosystem, animals, and people. This, however, is just one part of the story.
