Modern man has been awful rough on the oceans. With climate change acidifying the seas, and through overfishing, pollution, dead zones and resource extraction, humans have done an amazing amount of damage to the world’s aquatic ecosystems. Brendan Smith encountered many of these challenges as a commercial fisherman. After realizing that most current fishing practices were unsustainable, he decided to settle in Long Island Sound and raise oysters. As of last year, he integrated kelp into his practices, creating a 3D farm that could take advantage of the entire water column. Once he added the green-blue algae, he found that the seaweed and shellfish had great economic and environmental benefits.

Now the subject of a Kickstarter campaign, Smith is looking to expand his 3D farm and educate others as to the applications of kelp and shellfish. Known as the “rainforest of the sea”, kelp is able to capture an incredible amount of carbon at almost five times that of land based plants. His 2o acre farm alone can sequester up to 134 tons a year. Seaweed and oysters can also filter out nitrogen which is the main cause of dead zones created by agricultural runoff. His Thimble Island Oyster Co. farm sucks up 164kg of nitrogen annually, purifying the water and converting the nutrients into a healthy source of protein, vitamins, and minerals.

Kelp also possesses the added bonus of being a terrific feedstock for biofuel. According to the US Department of Energy, a kelp farm the size of Maine could potentially produce enough algae to replace petroleum for the entire country. Farming kelp has the ability to jump-start what Smith describes as a “Blue-Green Economy” that could not only help to repair damaged ecosystems, but create valuable jobs and revamp a crumbling infrastructure. Instead of drilling and contaminating the water supply, why not take advantage of natural processes that allow life to flourish?
