Professor Dickerson Despommier didn’t look to the ground when he thought of ways to solve the country’s food and water crisis—he looked up. Despommier, in a stroke of genius, thought skyscrapers could become America’s next agriculture frontier. His latest book, The Vertical Farm, describes how high rises are the perfect places for year round farming and could provide an alternative for areas lacking suitable farm land. Despommier is a professor of Environmental Sciences at Columbia University. Listen as he discusses his idea with Prime Time Radio host Mike Cuthbert.
