OBLIGATORY NAZI REFERENCE:

About a year ago, on March 26, 2012, Sandra Steingraber, an environmental writer and activist against natural-gas fracking, wrote a public letter titled "Breaking Up with the Sierra Club." Breakups are never easy, and the letter, published on the website of the nature magazine Orion, was brutal from the start: "I'm through with you," Steingraber began. 

The proximate cause of the split was the revelation that between 2007 and 2010 the nation's oldest environmental organization had clandestinely accepted $26 million from individuals or subsidiaries associated with Chesapeake Energy, a major gas firm that has been at the forefront of the fracking boom. "The largest, most venerable environmental organization in the United States secretly aligned with the very company that seeks to occupy our land, turn it inside out, blow it apart, fill it with poison," Steingraber wrote. "It was as if, on the eve of D-day, the anti-Fascist partisans had discovered that Churchill was actually in cahoots with the Axis forces."
