Bren Smith | Farming the ocean to fight climate change

In this episode, we talk with Bren Smith, a former commercial fisherman who is now the co-founder and co-executive director of Greenwave, a nonprofit dedicated to creating jobs and protecting the oceans through regenerative ocean farming.  

The oceans are taking a beating from climate change. It’s estimated that they have absorbed nearly a third of the carbon released by humans. This creates a whole host of problems as the carbon dissolves in saltwater, making it more acidic while making it harder for calcifying organisms like oysters and coral to grow.  

Fishermen like Bren are on the front lines of the changing climate, but Bren shares how the oceans can be a source of renewal. Bren discusses how his inexpensive system for regenerative ocean farming avoids the vices of land-based agriculture: it requires no inputs of pesticides, fresh water, or even land. But, it produces nutrient dense foods while absorbing carbon and nitrogen, creating habitat, reducing local ocean acidification, and mitigating the impact of storm surges. Bren shares what motivated him to provide open access to his farming designs, why he started a nonprofit, and how he evaluates new market opportunities that can support ocean farmers. Talking with Bren left us more optimistic about the future of the planet and we hope his story will inspire you as well.
