Why are the carbonate ion level in the water decreasing?

Carbon dioxide reacts with seawater to form carbonic acid, which releases hydrogen ions, reducing pH.The additional hydrogen ions released by carbonic acid bind to carbonate (CO32-) to form bicarbonate (HCO3–), decreasing the amount of carbonate in the water.
