Large-scale agriculture that destroys Ecosystems, and contributes, with the associated greenhouse gas emissions to climate change. Meanwhile, the fishing pushes in the seas to its ecological limits. “As a fisherman I have experienced it myself, as we took advantage of modern technology to the ever-decreasing number in addition to fish deeper into the ocean to drift,” says the canadian Bren Smith, founder of Green Wave. Therefore, he is convinced that The future lies not in fishing, but in Aqua cultures. The oceans could replace agriculture.

hurricanes devastated oyster farming

in the nineties, the cod stocks in the North Atlantic collapsed, recognized Smith, that his job was in a traditional sense, only little future. So the sailor tried first, with the traditional oyster farming, with cages on the sea floor. However, the hurricanes Irene and Sandy devastated in 2011 and 2012 up to 90 percent of their Crop, and showed Smith that the old methods of overhaul were in need of.

In his search for better ideas for robust underwater breeding joined Bren Smith on the work of the marine scientist Charles Yarish of the University of Connecticut. Yarish already stressed for decades that molluscs such as mussels and oysters, but seaweed will not only be the food of the future, but also for the Regeneration of the world’s oceans can contribute.

The feed mankind

So the concept of the so-called 3D Ocean Farming and gradually. Smith emphasizes the three-dimensionality, to describe how outdated the conventional idea is that fish and shellfish are either wide at the surface of the sea, or on a similar almost two-dimensional surfaces to grow on the ground. “We also need to use the space in between,” he says. So Smith developed a System of horizontal Ropes to the surface, which are associated with storm fixed buoys and platforms. From there, vertical ropes, then lead to cages on the seabed where oysters and Venus clams are bred. On the vertical Ropes of seaweed, especially Kelp grows, in addition, extra socks hanging on them, where mussels find. Other buoys, anchors, shells, vertical cages for Jacob.

This construct can withstand not only hurricanes, it stands out because of its vertical orientation also takes up significantly less space than conventional Aqua farms. Less than half a hectare of Smith can produce in five months, more than a quarter of a Million shellfish, and 10 to 30 tons of Kelp. “If we could only equip six percent of the surface of the seas of the world with our farms, we could feed humanity and the whole of the carbon emissions to neutralize,” says Smith.

No fertilizer, no antibiotics, no pesticides

“We don’t need fertilizers, we don’t need antibiotics, we need no pesticides.” The farms needed only the sea and the sun. The grasses and molluscs regenerate by the way, the maritime Ecosystem. They absorb nitrogen and phosphorus, two of the main die ‘polluter pays’ for the Sea, in addition, especially the carbon dioxide responsible for the Acidification of the sea water and global warming. Seaweed-can absorb areas per hectare is more than ten times as much carbon as a similarly large area of rain forest. And also the mussels and oysters are natural water treatment plants.

Smith thinks that the untapped oceans offer mankind a second Chance to create a better farming and nutrition system. In cooperation with the organization Surfrider, he has now developed a Manifesto for a New Blue Deal. This should create more jobs in Maritime environmental protection, eco-friendly energy sources off the coast of tapping and sustainable marine tourism.
