Underwater Vertical Seaweed Farm Restores Our Oceans While Providing Food and Fuel Source

Bren Smith has set up what he calls “3D ocean farms,” which “utilize the entire ocean column” to grow “restorative species,” including scallops, clams, oysters and kelp. Smith says this makes the oceans cleaner, healthier and more habitable, while providing jobs and food.

He hasn’t always been fishing that way. His story is one of “ecological redemption,” Smith said in a TEDx Talk (see below) in 2013. He dropped out of high school when he was 14 to work on fishing boats, working “at the height of the industrialization of the oceans. We were ripping up entire ecosystems with our trawls. We were using evermore efficient technology to chase fewer and fewer fish deeper and deeper into the ocean. And I’ve personally thrown tens of thousands of pounds of dead bycatch back into the sea,” he said.
