Days after possibly the largest anti-fracking protest in history, environmentalists delivered a petition to California Gov. Jerry Brown demanding a ban on the controversial practice. The petition, which contained 184,000 signatures, was delivered Monday by a coalition of environmental progress groups, including the California-based Courage Campaign, Daily Kos, 350.org, Food and Water Watch, CREDO, Environmental Action, Presente, Forecast the Facts, and RH Reality Check.
