As a chef in high-end restaurants and, later, in the home of then-Senator Barack and Michelle Obama, Sam Kass read a lot about how eating organic and buying local were the keys to remaking a food system otherwise built on climate-change-causing fossil fuels. But when he served the Obamas as a senior adviser in the White House, he realized something: While it's easy to identify the problems in our spoiled food system, fixing that system is not as simple as getting your eggs from the farmers market. It's going to take supporting promising new technologies, compelling businesses to sell us what we need, and changing policy and our culture. It won't be easy, and, frankly, time is not on our side. But the good news is that The Last Supper shows the path to saving our food, our planet, and our way of life.
