This Sustainable ‘Farm of the Future’ Is Changing How Food Is Grown

After working as an industrial fisherman for decades and witnessing the devastating effects of mass-fishing, Bren Smith decided to look for more sustainable ways to feed the planet.

A few years ago, he developed an unique, vertical 3-D ocean farming model: a sort of underwater garden composed of kelp, mussels, scallops and oysters. Those species are not only edible and in high demand, Smith explains, but they also act as a filter for nitrogen and carbon dioxide, rebuilding natural reef systems and restoring our seas. In 2013, Smith launched the nonprofit GreenWave to help other fishermen replicate his innovative farming model. “This is our chance to make food right and agriculture right,” he says.

Kelp: The Sea Weed That Could Save Mankind

Bren Smith blends into the New England seascape, a waterman decked out in waders tooling around on his boat in the Long Island Sound. On this hazy July morning, he’s motored out aboard the Mookie III from a Stony Creek, Conn., dock to check on his oyster beds scattered between the Thimble Islands. Another boat putters by, and Smith raises his arm to point, his hands cloaked in rubber gloves to protect against the barnacles. “That guy,” Smith says, “is only catching about five pounds of lobsters a day. He doesn’t even pay for half his fuel with that.” And with this observation, Smith shatters the illusion that he’s just another fisherman chasing his catch.
Smith, in fact, is a genuine revolutionary, a man who sees powerful currents of change in the choppy waters off the Atlantic seaboard. And his neighbor, chugging past with his nearly empty hold, is proof that the end of a way of life is looming—and the beginning of a new one is at hand.
Climate change has affected the fishing beds. Ocean acidification, a product of rising atmospheric CO2 levels, kills off coral reefs, causes toxic algae blooms and dissolves the shells of oysters and other mollusks, researchers say.
And then there’s what Smith calls the “rape and pillage” of the world’s oceans—the overfishing that has dried up once-fertile sources of food, and sent unemployment in once-thriving seaside communities through the roof. Smith assigns himself a share of the blame. He fished for McDonald’s in the Bering Sea some years back, and pushed the cod stocks to the brink. But grousing about it, and hoping government regulation will solve the problem, won’t do the trick. What fishermen catch needs to be rethought. What fishermen should be doing, in Smith’s view, is harvesting kelp.
Yes, you read that right: the slimy brown sea vegetation that has grossed out generations of New England beachgoers. You might think of it as an annoyance of no particular significance to mankind. Smith sees it as a jobs program, an amazing source of nutrition, a strategic adaptation to the havoc being wrought by global warming—and, quite possibly, the next big thing in trendy New York City restaurants.
He calls it his “path of ecological redemption,” and he’s calling on fishermen, businessmen and consumers to follow it with him.
