Protecting wild spaces helps to conserve the species that call them home — and is one of the best strategies for meeting global climate goals.

Hear from a conservationist who has helped protect 15 million acres of land and 30 million marine acres in South America, and the US National Park Service’s first indigenous director on the ways that wilderness transforms people and the planet.
