People are also starting to recognise the nutritional potential of algae, including seaweed. Some types, when dried, contain 70 per cent protein; others are packed with essential fatty acids. Seaweeds are abundant in micronutrients, too, from iron and zinc to potassium and calcium. There are more than 100,000 species of algae, yet we currently cultivate just 20, so there’s plenty of scope for expansion. A big advantage of algae is that its cultivation doesn’t require agricultural land: it can be done offshore or in places where the groundwater is salty, even in the Sahara.
