Increased investment in algae aquaculture systems could be a means of meeting nutritional needs while reducing the ecological footprint of food production. Microalgae can provide high amounts of protein, essential amino acids, as well as other micronutrients, such as vitamins and antioxidants. A marine microalgae-based aquaculture industry wouldn’t require arable land and freshwater, or pollute freshwater and marine ecosystems through fertilizer runoff. Agriculture’s potential to meet the world’s nutritional demands by 2050 are limited. Marine microalgae can help fill the projected nutritional gap while improving overall environmental sustainability and ocean health, although there are challenges.
