Consider the following statements about the effects of ocean acidifica...
  • Carbonate ions are essential to the calcification process that allows certain marine organisms to build their calcium carbonate shells and skeletons (e.g. hard tropical corals, cold-water corals, molluscs, crustaceans, sea urchins, certain types of plankton, lobsters, etc).
  • However, increases in atmospheric CO2 levels lead to a decrease in pH level, an increase in the concentration of carbonic acid and bicarbonate ions, causing a decrease in the concentration of carbonate ions.
  • Thus carbonate ions are less available and calcification is, therefore, harder to achieve, and maybe prevented altogether. Imagine trying to build a house while someone keeps stealing your bricks.
