When humans first entered North America from Asia more than 13,000 years ago, their survival may have depended on fish that were plentiful thanks to coastal kelp. Today, we still rely on seaweed’s many benefits. We use it as a delicacy to wrap round sushi, extract its chemicals for use in industry and turn it into recyclable plastics. But its potential doesn’t end there. Large-scale seaweed farms could clean up Earth’s oceans, restoring biodiversity and increasing the productivity of aquaculture. They could suck carbon dioxide from the air, and help curb the emission of other greenhouse gases. According to some researchers, it could even be crucial to saving civilisation. Seaweed still has a long way to go to fulfil those lofty ambitions. Some wild populations have been overharvested, and the potential for farming has barely been tapped.
