Estimates indicate that by 2050, at least 9 billion people will inhabit planet Earth. Food scientists, environmentalists, industry advocates, farmers, and policymakers disagree about how best to sustain a global food supply. Many assume that the solution will involve petroleum-based fertilizers and concentrated animal feedlot operations (CAFOs). According to Joel Salatin, a third-generation alternative farmer from Polyface Farms in Swope, Virginia, nothing could be further from the truth.
Salatin promotes localized, solar-driven, carbon-fertilized and yet scalable agricultural systems. He is the author of eight books and is featured prominently in the film documentaries 'Food, Inc.' and 'American Meat.'
In a University Lecture Feb. 12, 2015, Salatin articulated a viable, sustainable model that challenges prominent assumptions about what is required to feed the world.
