Today, Matt speaks with award-winning journalist and author Michael Grunwald about his new book, We Are Eating the Earth: The Race to Fix Our Food System and Save Our Climate. Grunwald makes the case that food and land use are responsible for roughly a third of global greenhouse gas emissions — a massive blind spot in most climate conversations. They discuss why the world is on track to eat 70% more meat by 2050, the limits of veganism and organic farming as climate strategies, and why Denmark’s 2025 agricultural policy may be the most important climate legislation most people have never heard of. They also dig into deforestation, food waste, agricultural subsidies, the failure of alternative meats, and what a serious food-climate agenda might actually look like.
