The number of ocean going birds has declined by 70% since the 1950s. New research shows how projects bringing them back can also bolster ocean ecosystems that sequester carbon. Seabirds distribute nutrients that are beneficial to plankton, seagrass and coral reefs, which nurtures fish populations that are eaten by seabirds and marine mammals. This creates a cycle that forms a biological carbon pump. Read more about it on Inside Climate News.
