But because CO₂ has an acidifying effect on seawater, as the kelp absorb the CO₂ the water becomes less acid. The CO₂ is taken out of the water in much the same way that a land plant takes CO₂ out of the air. The kelp draw in so much carbon dioxide that they help de-acidify the water, providing an ideal environment for shell growth. The technology allows for the production of about 40 tonnes of kelp and a million bivalves per hectare per year.
