Detailed explanation-1: -Seaweed has long been discussed as a method of capturing CO₂-one that is more efficient than trees and vegetation while also not using up valuable land space.

Detailed explanation-2: -Through the process of photosynthesis, kelp absorbs CO2 into its tissues. Because of their rapid growth, they have incredible capacity to store  200 million tons of CO2 per year. But their potential for natural carbon sequestration has been estimated to be 1-10 billion tons annually!

Detailed explanation-3: -Because kelp are photosynthesizers, they draw carbon dioxide from the water perhaps making conditions less acidic and therefore more favorable for many marine organisms.

Detailed explanation-4: -Scientists have discovered that microscopic plants called diatoms absorb 10-20 billion tonnes of carbon dioxide (CO2) every year as they float on the surface of the ocean. That’s equal to the amount of carbon captured annually by all of the world’s rainforests.

Detailed explanation-5: -This study revealed that kelp forests in Australia sequester approximately 1.3-2.8 teragrams of carbon per year. Thus, kelp forests account for 30% of the total blue carbon sequestered annually in Australia, and about 3% of the total global blue carbon budget.
