The narrative of the film focuses on Marty Travis, a seventh-generation farmer in central Illinois who watched his land and community fall victim to the pressures of big agribusiness. Sustainable is a film about the land, the people who work it and what must be done to sustain it for future generations. A vital investigation of the economic and environmental instability of America’s food system, from the agricultural issues we face - soil loss, water depletion, climate change, pesticide use - to the community of leaders who are determined to fix it.
