6. What role does ocean acidification play in affecting marine life?

Ocean acidification is the process by which the pH level of the ocean decreases due to the absorption of carbon dioxide (CO2) from the atmosphere. This decrease in pH can have significant impacts on marine life, particularly organisms that rely on calcium carbonate to build their shells or skeletons, such as corals, mollusks, and some types of plankton.<br /><br />As the ocean becomes more acidic, it becomes more difficult for these organisms to build and maintain their calcium carbonate structures. This can lead to slower growth rates, weaker shells, and increased mortality. Additionally, ocean acidification can affect the behavior and physiology of other marine animals, such as fish and invertebrates, potentially altering their reproductive cycles, growth rates, and immune systems.<br /><br />Overall, ocean acidification poses a significant threat to the health and diversity of marine ecosystems, and its effects are expected to worsen as CO2 emissions continue to rise.
