Nate Chisholm is a rancher, ecologist, and entrepreneur who set out to learn how to manage savanna vegetation—the evolutionary homeland of our species—by working with innovative grazers and foresters around the world. That work led him to launch several ranching ventures that increased biodiversity and food production across vast acreages. Along the way, he realized that restoring savanna wasn’t just about shaping land; we need to look at the ecosystem of our ancestry to understand ourselves and if we are to have any hope of solving modern problems.

He lives in Kenya with his family, a herd of cattle, and most of the iconic wildlife of the African savanna, where he continues to study and protect the ecosystems that built the human mind.
