WebSeagrass captures carbon up to 35 times faster than tropical rainforests and, even though it only covers 0.2% of the seafloor, it absorbs 10% of the ocean’s carbon each year, making it an incredible tool in the fight against climate change. Seagrass is vital for marine life, which depends on the meadows for food and shelter.
