Ocean acidification refers to the process by which the ocean becomes more acidic due to the absorption of excess atmospheric carbon dioxide (CO2). This phenomenon is primarily driven by human activities, such as the burning of fossil fuels, deforestation, and certain agricultural practices, which release large quantities of CO2 into the atmosphere. When CO2 dissolves in seawater, it forms carbonic acid, which lowers the ocean's pH and leads to a more acidic environment.
