The main cause of ocean acidification is the increased absorption of carbon dioxide (CO2) from the atmosphere, which dissolves in seawater and forms carbonic acid. This process lowers the pH of the oceans, making the water more acidic. Ocean acidification threatens marine ecosystems, particularly organisms that rely on calcium carbonate to form their shells, such as corals, mollusks, and some plankton, which are critical to marine food chains.
