In 10 seconds? Just like trees, seaweed uses photosynthesis to convert carbon dioxide (CO2) into more seaweed. Using huge amounts of CO2 in the process, seaweed grows extremely fast and is a potential candidate for carbon sequestration.
So, how does kelp help in cutting carbon? Through so-called “blue carbon” initiatives. This method focuses on storing large amounts of carbon in marine plants and underlying soil. Systems such as mangroves and salt marshes capture and hold CO2 acting as a huge carbon sink. When these systems are destroyed, they emit the carbon they have captured, adding to greenhouse gases.
