<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Acidification can have several negative effects on oceanic life forms. For example, a drop in the pH of the ocean water (commonly known as ocean acidification) can make it difficult for certain species of coastal life to create their exoskeletons, which is essential for their survival. Therefore, ocean acidification can contribute to a loss of biodiversity. It also leads to migration of some aquatic species.
Ocean acidification reduces the amount of carbonate, a key building block in seawater. This makes it more difficult for marine organisms, such as coral and some plankton, to form their shells and skeletons, and existing shells may begin to dissolve.
