Our bodies are naturally wired to conserve energy, a trait inherited from ancestors who faced food scarcity. Even today, we expend about 1,400 calories daily just to stay alive, leading us to instinctively avoid unnecessary physical activity despite readily available energy sources. This perspective, distinguishing between athletic performance and true health, is explored by Daniel Lieberman, a Harvard professor of Human Evolutionary Biology.

Ellen MacArthur and Christiana Figueres met with BBC's Sumi Somaskanda at NYC Climate Week to discuss the Global Plastics Treaty. They highlighted this critical opportunity to address plastic pollution through a globally coordinated, legally-binding agreement.

Existing solutions and efforts by the Ellen MacArthur Foundation demonstrate the power of collective action. Final UN Global Plastics Treaty negotiations in Busan, Korea, this November offer a chance to establish ambitious, global rules for the entire plastics life cycle, transforming the system and preventing waste. The Foundation promotes a circular economy to eliminate waste and regenerate nature.

Extractive farming practices have driven a planetary emergency, depleting nature and impacting climate, biodiversity, and public health. With agriculture using half our land, farmers are crucial stewards. We must redesign systems from extraction to regeneration and sustainability.

In this talk, Henry Dimbleby, lead non-executive director for DEFRA and architect of the National Food Strategy, addresses the complexity of food systems and the urgent need for a common language to measure farming sustainability.

Henry co-founded Leon Restaurants, the Sustainable Restaurant Association, and Chefs in Schools, bringing extensive expertise to this TEDx event. Learn more at ted.com/tedx.
