Seaweed and giant kelp are sometimes called “the sequoias of the sea.” Yet at a time when so many people are talking about climate solutions and reforestation — there aren’t nearly enough people talking about how the ocean can be part of that. In part one of our two-part series, we go out on the water to see how seaweed can play a role in addressing climate change, and how a fisherman named Bren Smith became kelp’s unlikely evangelist.

Guests: Bren Smith and Casey Emmett

Calls to action: 

• Check out Bren Smith's book called “Eat Like a Fish”

• Start your own hatchery, farm, or underwater garden: Check out the University of Connecticut and Ocean Approved manuals and GreenWave’s Regenerative Ocean Farming toolkit. 

• Study ocean agriculture through the Algae Technology Education Consortium (ATEC) at the community college level or through Coursera courses Intro to Algae and Algae Biotechnology.
