The only evidence of Bren Smith's thriving farm is a few buoys floating in the long island sound. Amongst Connecticut's beautiful Thimble Islands, he is pioneering 3-D ocean farming. Where he uses the entire water column to grow his own ecosystem. Bren's Thimble Island Oyster Co. cultivates clams, oysters, mussels, and long lines of olive-green kelp. Lots of kelp. Thanks to our sponsor, Whole Foods Market.

"We have this exotic crop that's also local. These chefs have gotten excited about making kelp ice cream and butter." [0:35]
