NBSV 219: Cycling 30,000 km for the planet: plant-based athletes Leanna Carriere and Dr. Timm Döbert

Leanna Carriere and Dr. Timm Döbert are preparing to cycle 30,000 km from Alaska to Chile as part of their Wings of Survival project, following migratory birds and raising awareness about biodiversity and climate. We talk about how they fuel extreme endurance—like cycling 150 km a day and eating up to 10,000 calories—entirely on a vegan diet. We also dig into the environmental side: land use, why animal agriculture doesn't scale, and what real change could look like over the next decade. This conversation is part science, part storytelling, and part "wait…that's humanly possible?"
