Fish can do it by producing and excreting carbonates THE marine carbon cycle is undergoing rapid changes. An excess of unregulated carbon will eventually acidify the oceans. A new study demonstrates that fish have the potential to save the marine carbon cycle. Until now scientists believed that the calcium carbonate (CaCO3), which makes seawater alkaline, came from the external
