When you clean out your fridge, do you find yourself tossing good food that’s gone bad? As much as 40 percent of the American food supply goes to waste each year, at a cost of more than 160 billion dollars. Why is so much food discarded while 14 percent of American households suffer from food insecurity? RoniNeff, of the Johns Hopkins’ Center for a Livable Future, explains how our consumer culture encourages needless buying, as well as how wasted food impacts the environment. Plus, Beth Martino, president of the Maryland Food Bank, discusses how the nonprofit works with grocery stores and farms to redirect food that’s headed for the landfill.
