If phytoplankton decreases or changes distribution, then fisheries may also see reduced catches or fish moving out of the area entirely. Cyanobacteria are a very numerous, ancient, and widespread type of phytoplankton. They were believed to have transformed the ancient atmosphere of Earth from being high in carbon dioxide to high in oxygen, paving the way for the evolution of life as we know it.
