Bestselling author Thomas Kostigen talks about climate change and specifically how we can all decrease our carbon footprints by making different food choices. “If we were to embrace more types of food rather than what is just basically pushed upon us by the food system, then we might have a chance to change things in a bigger way,” he says. ““It isn't that easy to understand how much [each] food stores carbon.” Kostigen recently partnered with actor and philanthropist Robert Downey Jr. on Cool Food: Erasing Your Carbon Footprint One Bite at a Time, which serves as a guide to help us all make better food choices. See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
