The seas are not greener because we have more phytoplankton. Also, there are many species of phytoplankton, some even harmful, so it may mean changes in their biodiversity. https://www.scientificamerican.com/article/phytoplankton-population/ https://www.scientificamerican.com/article/phytoplankton-pop... Phytoplankton Population Drops 40 Percent Since 1950 https://www.pnas.org/doi/10.1073/pnas.2019591118 https://www.pnas.org/doi/10.1073/pnas.2019591118 Phytoplankton biodiversity is more important for ecosystem functioning in highly variable thermal environments https://www.nature.com/articles/s41467-021-25699-w https://www.nature.com/articles/s41467-021-25699-w We find that the rate of turnover in the phytoplankton community becomes faster during this century, that is, the community structure becomes increasingly unstable in response to climate change. Combined with alterations to phytoplankton diversity, our results imply a loss of ecological resilience with likely knock-on effects on the productivity and functioning of the marine environment.
