‘Giant kelp is among the best organisms on the planet for taking planet-warming gases out of the atmosphere. Buoyed by small, gas-filled bulbs called \u201cbladders,\u201d these huge algae grow toward the ocean surface at a pace of up to two feet per day. Their flexible stems and leafy blades form a dense underwater canopy that can store 20 times as much carbon as an equivalent expanse of terrestrial trees.’<\/p>\n
