Resistance movement
Keith is associated with the Deep Green Resistance movement, and together with Aric McBay and Derrick Jensen, she co-wrote "Deep Green Resistance: Strategy to Save the Planet", published in May 2011. The book describes itself as a "manual on how to build a resistance movement that will bring down industrial civilization and save the planet," and "evaluates strategic options for resistance, from nonviolence to guerrilla warfare, and the conditions required for those options to be successful."
