Multi-species 3-D ocean farms
In recent years, scientists and entrepreneurs have been working on ways to create a more sustainable food system. GreenWave, on Long Island, has accomplished that by setting up "multi-species 3-D ocean farms" growing seaweed, scallops, mussels, clams, and oysters.
The vertical seaweed gardens are designed to provide an alternative for communities that can no longer rely on fishing. Seaweed farms have the capacity to grow huge amounts of nutrient-rich food, and oysters can act as an efficient carbon and nitrogen sink.
GreenWave is a winner of the prestigious Buckminster Fuller Institute prize for the project “world’s first multi-species 3-D ocean farm,” a vertical underwater garden that aims “to restore ocean ecosystems and create jobs in coastal communities by transforming fishers into restorative ocean farmers. The sustainable underwater farms may offer a new source of income for fishermen who can no longer rely on fishing. Read More>
Instead of monolithic factory fish farms, GreenWave see the oceans as the home of small-scale farms where complementary species are cultivated to provide food and fuel -- and to clean up the environment and fight climate change. Smith believes seaweed is a viable alternative because it is healthy and sustainable. Instead of harming the ocean, seaweed farms actually help to pull pollution out of the water. In short, seaweed gardens can actually remove carbon dioxide and nitrogen from the ocean.
Governed by an ethic of sustainability, they are re-imagining our oceans with the hope of saving us from the grip of the ever-escalating climate, energy, and food crises.
