Answer :
Researchers are trying to find strategies to boost the amount of calcium carbonate in the oceans.
As ocean acidification increases the amount of carbonate ions available, they bond with too much hydrogen, making fewer carbonate ions available for calcifying organisms to build and maintain their shells, skeletons, and other calcium carbonate structures. Calcium carbonate is a compound called CaCO3, which is found in nature as calcite and aragonite as well as in plant ashes, bones, and shells. Increased atmospheric CO2 concentrations result in processes in the water that lower the pH and the amount of calcium carbonate, which is why ocean acidification refers to the lowering of sweater pH and carbonate saturation that follows.
