50. Danielle Nierenberg and Ellen Gustafson, Co-Founders, The Food Tank
Nierenberg and Gustafson, two longtime food activists, launched The Food Tank in January 2013 with one mission: to find a way to fix the world’s broken food system. By organizing events that bring together farmers, businesses, workers, nonprofits, local activists, academics, policy-makers, industry, journalists, community organizations, the funding and donor communities, and everyone else in the food world under one roof, they hope that they can get the conversation started and work toward a perfect worldwide food system. "The question that’s been asked historically has been, 'How can we grow more food?'" Gustafson told us last year. "When in reality what we should be asking is, 'How do we develop agricultural systems to get people to eat healthy? Foods with a low disease rate, a good environmental outcome, and long-term yields." The answers won’t come easy, but if anyone ever had the knowledge and wherewithal to seek them out, it’s these two.
