Living marine resources

8. Development of algae as a sustainable food source
Algae have evolved to be highly efficient in resource use and have proven to be a viable source of nutritious biomass that could solve many of the current problems of food production. Seaweed inherently possesses the desired qualities of a sustainable food source, as it produces highly digestible proteins, lipids and carbohydrates and is rich in essential fatty acids, vitamins and minerals.
