A pioneering Giant Kelp farming project is helping to remove CO2 from waters off Namibia's rugged Atlantic coast — and boost economic growth. In the cold, nutrient-rich waters, underwater forests are being cultivated to capture carbon, support marine biodiversity, create jobs and produce the ingredients for fertilizer. Kelp Blue is still tracking the farm's carbon sequestration performance.  Supporters believe large-scale kelp farming could aid in the fight against global warming. Giant Kelp is one of nature’s fastest-growing organisms.
