Speciesism: The Movie(2013)

Overview:

Modern farms are struggling to keep a secret. Most of the animals used for food in the United States are raised in giant, bizarre factories, hidden deep in remote areas of the countryside. Speciesism: The Movie director Mark Devries set out to investigate. The documentary takes viewers on a sometimes funny, sometimes frightening adventure, crawling through the bushes that hide these factories, flying in airplanes above their toxic manure lagoons, and coming face-to-face with their owners.
