Seaweed is better at absorbing CO2 emissions than trees are. Seaweed is considered a high-value source of protein for humans and livestock. We’re all familiar with the role forests play when it comes to providing a sustainable source of food, energy and raw materials, and locking away CO2 emissions. But perhaps we’re less knowledgeable about the potential of forests of seaweed growing in the oceans. A type of seaweed known as kelp is being developed for its nutritional value and its ability to absorb and lock away huge quantities of carbon dioxide. Seaweed absorbs CO2 more effectively than trees. It also improves water quality by extracting harmful nutrients such as nitrogen from the sea.
