Can you imagine living next door to a giant, stinking cesspool the size of four football fields? People who live near pig farms that supply Smithfield Foods can. These gigantic lakes of urine and feces were documented in a unique way by Mark Devries—the award-winning director of the 2013 documentary Speciesism: The Movie. For the past two years, Devries has been using drones to investigate and expose the environmental devastation caused by factory farming. He captured shocking aerial footage of the massive facilities that churn out pigs for Smithfield Foods and the enormous waste lagoons that result.
