What is Ocean Acidification?
Ocean Acidification
Ocean Acidification is the process where the ocean becomes more acidic due to the absorption of excess carbon dioxide from the atmosphere. This change in acidity can harm marine life, particularly organisms with calcium carbonate shells or skeletons, such as corals and some shellfish.
Overview
Ocean Acidification occurs when carbon dioxide (CO2) from the atmosphere dissolves in seawater, forming carbonic acid. This chemical reaction reduces the pH level of the ocean, making it more acidic. As the ocean absorbs more CO2 from human activities like burning fossil fuels, the acidity increases, posing a threat to marine ecosystems. The impact of Ocean Acidification is particularly significant for marine organisms that rely on calcium carbonate to form their shells and skeletons. For example, coral reefs, which are vital to marine biodiversity, can suffer from weakened structures, making them more vulnerable to erosion and less able to support the diverse marine life that depends on them. Shellfish like clams and oysters also face challenges, as their ability to build shells diminishes in more acidic waters. Understanding Ocean Acidification is crucial within Environmental Science because it highlights the interconnectedness of human activities and natural systems. As the ocean changes, it can disrupt food chains and affect fisheries, which many communities rely on for their livelihoods. Protecting the ocean from further acidification requires global efforts to reduce carbon emissions and promote sustainable practices.
