Most Americans - and a growing number of people around the world - now eat meat that was grown on factory farms. The brutal, inhumane conditions in which factory farm animals are raised calls into question not just the ethics of eating meat but the very foundations of the democracy we like to believe we live in. CAFOs - Concentrated Animal Feeding Operations - crowd tens of thousands of animals together in their own filth, pumping them full of antibiotics and feed that their bodies are not designed to digest.
