Consequently, in a process known as ocean acidification, this CO2 reacts with water molecules and lowers the ocean pH, making it more acidic.
This process also removes carbonate, an essential ingredient needed by corals and other organisms to build their skeletons and shells. As a result, these calcifiers are struggling in Earth's changing oceans, and...
