New food source may come from one of Earth’s oldest life forms

Since microalgae can be grown with far fewer resources than land-based plants and animals, they could provide a vast resource for new food and beverage products.

Microalgae, one of Earth’s oldest life forms, may soon become a new food source for people and animals. Scientists have identified more than 30,000 species of algae and there are estimates that ten times as many species could exist.

These microscopically small algae, which form the basis of the planet’s food chain, grow 10 to 30 times more quickly than land plants and turn carbon dioxide into oxygen more efficiently than most trees and grasses. Since they can be grown with far fewer resources than required for land-based plants and animals, they could provide a vast resource for new food and beverage products and cosmetics.

Algae “invented” photosynthesis around three billion years ago and are still responsible for producing nearly half the oxygen in our atmosphere. Since they can efficiently turn carbon dioxide into oxygen, algae are also prime candidates for solutions to man-made climate change due to rising carbon dioxide emissions.

According to a Nestle study entitled “How Will Germany Eat in 2030?”, the fact that algae can be efficiently cultivated is enough to ensure they will become a part of our future diets.
