when carbon dioxide (CO2) is
absorbed by seawater, chemical reactions occur that reduce seawater pH,
carbonate ion concentration, and saturation states of biologically important
calcium carbonate minerals. These chemical reactions are termed "ocean
acidification". Ocean acidification is
expected to impact ocean species to varying degrees. Photosynthetic
algae and sea grasses may benefit from higher CO2 conditions in the ocean, as they require CO2 to live just like plants on land. On
the other hand, studies have shown that a more acidic environment has a
dramatic effect on some calcifying species, including oysters, clams, sea
urchins, shallow water corals, deep sea corals, and calcareous plankton. When
shelled organisms are at risk, the entire food web may also be at risk.

How does the carbon dioxide (CO2) level in the atmosphere affects the coral's life in the ocean?
