" Originally, all foods were “organic”—grown without synthetic pesticides, herbicides, chemical fertilizers or hormones. Large-scale farming with chemicals began around World War II, around the same time that food processing exploded. Large-scale farming works against the natural cycles of the earth, relying on chemicals to produce big returns. This process has depleted much of the world’s soil of its minerals and nutrients. The resulting vegetable and animal foods are not only deficient in nutrients, but they are also full of pollutants and agrochemicals. "
