Among sustainable systems emerging, “Regenerative Ocean Farming” is the most promising. Pioneered by former cod fisherman Bren Smith, born in Maddox Cove, Newfoundland; “Restorative ocean farms“ are designed around kelp seaweeds (mostly kelp, <i>Laminariales</i>) and shellfishes. This model requires very low capital costs as it is based on underwater “scaffoldings of rope” attached to floating buoys. Cheap to build, a restorative farm can be put together in two days. This implies that a farm can be built sporadicly for one single season, or kept active all year round. Other than sucking up the excess of nutrients (mainly nitrogen responsible for eutrophisation) by intensive agriculture upstream, seaweeds can actually absorb large quantities of carbon dioxide. Ocean acidification being caused by excess anthropogenic CO2 from the air migrating in the oceans, cultivating fireproof seaweeds forests able to absorb CO2, might be even more durable than land forests. Seaweed makes cheap and reliable base material for biodegradable paper and cardboard; but also provide healthy habitats for other species to thrive in. This is where shellfish comes into play: requiring zero input such as fertiliser, fresh water or feed, shellfish can simply grow and filter the water which will later help the seaweed grow.<ref>The Soft Protest Digest, Fishing series: How to better farm the ocean?
