Consider what we are up against: today just four or five corporations control nearly every aspect of food, from seeds to commodity crops like grains, food processing, meat production and supermarkets. These firms’ intrinsic need to leverage massive volumes of seemingly cheap food propels a chain of exploitation: farmers pressured into unsustainable monocropping using pesticides; farm workers and meatpackers abused and underpaid to keep food “cheap”; and consumers (and taxpayers) footing the bill — in excess of $100 billion a year — for health ailments stemming from this food, which is not so cheap after all.
