About this episode:

American farms, restaurants, retailers, and households throw out nearly 30% of the food in our system, landfilling millions of tons of food each year and draining resources like land and energy. Households generate the most waste, with everyday cooks overbuying at grocery stores and throwing away a substantial portion of their purchases—but getting ahead of those scraps can make a big difference. In this episode: ReFED’s Dana Gunders covers the environmental costs of food waste and shares immediate action items to better manage it.

Guest:

Dana Gunders is a national food systems expert and the president of ReFED—an organization that researches and promotes evidence-based action to end food waste.

Host:

Stephanie Desmon, MA, is a former journalist, author, and the director of public relations and communications for the Johns Hopkins Center for Communication Programs at the Johns Hopkins Bloomberg School of Public Health.
