Self-described 'radical' farmer Joel Salatin shares his ideas on how to revolutionize the global food system.I googled the name, and came up with this website about his farm. Happy cows, happy chickens, etc, all being rotated around a small parcel of land in a way that makes use of nature. Cows eat perennial grasses. When the section they're eating gets mowed, they get moved onto the next section. Three days later, the chickens are sent in to eat the maggots that are living in the cow patties, before they can hatch into flies and cause a fly problem. The chickens scatter the cow patties, helping to fertilize the grasses. A couple of weeks later, the cows are back in that chunk of lush field, and the circle of life continues.
