Up to 0.55 gigatonnes each year: this is the potential for eliminating atmospheric CO2 that brown algae would possess, according to a recent study by German scientists.
Composed of chlorophyll and a pigment called "fucoxanthin", brown algae grow in a marine environment and are capable of absorbing large quantities of carbon dioxide, which they then release into the water in the form of carbohydrates.
