The existential threat posed by climate change can often obscure the more immediate vulnerabilities that regulatory bodies like the Environmental Protection Agency guard against. As Scott Faber of the nonprofit research organisation Environmental Working Group put it, "The EPA is the only guarantee that when you turn on your tap your water isn't full of shit." So it's alarming that Scott Pruitt, newly confirmed administrator of the Environmental Protection Agency, once worked on behalf of donors in Oklahoma to stop his new employer from keeping literal chicken crap out of the water.
