"Oysters may struggle to build shells as carbon dioxide rises."

When baby oysters are born, they must gather enough energy to build a shell before they can capture outside food and be able to eat and survive.  The energy used to make the shell is heavily relied on energy derived from their eggs.  The eggs contain many different forms of carbon, and research shows that the oysters rely on the eggs resources from more than a week.  However, due to the dependence on these resources, the oysters could experience many problems in response to the rise of atmospheric carbon dioxide.  The more carbon dioxide the ocean takes in, the more trouble it will be for the oysters to find energy to build their shells.  Calculations show that the more carbon dioxide dissolved in water means the more energy an oyster must find to build a calcium carbonate shell.  A possible solution to this problem would be to drop the carbon dioxide productions.  However, the falling pH in the ocean could make the building of oyster shells impossible.  Hatcheries could possibly stable the pH in the ocean, but the only true way to help the pH is to initially decrease the carbon dioxide productions.  I believe that more research must be done, and the more research could reveal more solutions to this problem.  Possible solutions that could give oysters the availability of more calcium could help the problem.
