I collaborated on this piece with Kip Anderson, co-director (with Keegan Kuhn) of Cowspiracy.
Yesterday, thousands of environmentalists are marching through the streets of New York. They do so to undertake what environmentalist Bill McKibben calls "the biggest demonstration in the history of the climate movement." The driving motivation for the first People's Climate March is a fiercely grassroots message as inspiring as it is true: "movements can shift political power. In fact, little else ever does."
History demonstrates that McKibben is correct, but with one critical caveat: the movement must be focused on the right targets. It is on this point that yesterday's march, for all its passion, could lead the environmental movement down a jagged path.
Modern environmentalism assumes that our ecological fall from grace began a century ago with the transition to fossil fuels. This assumption explains the movement's focus on gas pipelines and university divestment from fossil fuel multinationals. While it's certainly true that our reliance coal, oil, and gas remains endemic to our current ecological predicament, our original environmental sin is rooted in an older and more fundamental transition: the domestication of animals.
