What Is Ocean Acidification And Why Does It Matter? |
|
Answer» DIRECT OBSERVATIONS of ocean chemistry have SHOWN that the chemical balance of seawater has shifted to a more acidic STATE. Some marine organisms (such as corals and some shellfish) have shells composed of calcium carbonate, which dissolve more readily in ACID. As the acidity of seawater increases, it becomes more difficult for them to form or maintain their shells.
