On a sunny day in Choma, Zambia, Cornwell Hademu shares a traditional drink—and a powerful idea. In this season finale of Nature Answers, we meet Kelvin Siafweba and the team from Happy Planet, a cooperative of people recovering from addiction who are turning agricultural waste into sustainable charcoal and soil-enhancing biochar.

But this episode is about more than just climate solutions. It’s about second chances.

Learn how biochar—an ancient soil amendment with roots in the Amazon—is helping Zambian farmers restore their land and helping people recovering from substance use reclaim their lives. Together with Cornwell, this group is proving that nature-based solutions can support climate resilience, community health, and economic opportunity—all at once.

This episode is hosted by Ivy Prosper, produced by Sarah St-Pierre and edited by Tara Sprickerhoff
