Ceurstemont investigates how an aquacultural revolution is taking place that could change humans' relationship with the sea. Seaweed cultivation is not new. In East Asia, a $5 billion crop is harvested every year, mostly for food. But other than nori, edible seaweed in the Porphyra genus also known as layer--which can sell for around $15 a kilogram--most uses of seaweeds have been low value. They are an energy-boosting additive for animal feed. Extracts are also widely used as natural fertilisers and as thickening agents in products ranging from toothpaste to paint. But seaweed has far more valuable uses. Certain species contain unique substances that could have important medical applications.
