Growing protein from tiny algae uses way less land and water than raising cows — like 95% less land and way less water — so it could be a smarter way to make food without hurting the planet.

Similar Assertions

Algae-based protein is way more expensive than soy protein—like 5 to 10 times more—so even though it's better for the planet, it's too costly to make on a big scale right now.
