Did you know that the ocean plays a vital role in controlling the planet’s temperature, as well as providing food, minerals, and half of the oxygen we breathe? Another important role is balancing the amount of carbon dioxide gas in the atmosphere. Unfortunately, due to large emissions of carbon dioxide over the past few centuries, the ocean is becoming acidic. This process is called ocean acidification. Ocean acidification affects many sea organisms, especially those with shells, like mussels and corals, but it can also affect other animals’ sense of orientation, like fish. Scientists are discovering more about the potential impacts of ocean acidification on the marine system and, consequently, on humans and other life forms who depend on or explore the ocean. In this article, we explain why ocean acidification started, where it has been detected, its present and future impacts on marine life, and how we can help correct it.
