In front of the largest crowd of the season, Jack Griffin (Society member) presented a fast-paced program  covering both the history of vertical farming and the groundbreaking progress of his own business, Metropolis Farms.   Jack covered the science, economics, and politics of establishing highly efficient food production in an urban setting.  He emphasized the breakthroughs his company has achieved in new designs to create a modular system which is open to any enterprising entrepreneur.  Additionally, Jack spoke eloquently about the potential for new employment opportunities in our urban centers as well as the provision of nutritious, quality food at reasonable prices. He shared that the potential exists for an altogether new sector of agriculture to emerge in our urban centers. Jack outlined some of the challenges facing the expansion of these new enterprises, including making USDA a viable partner in research, development, and implementation. Everyone in attendance on June 1 left with much to think about and the challenges facing technological innovation in agriculture.
