Yes, the oceans are becoming more acidic and this process is known as ocean acidification. This is a result of growing concern about carbon dioxide (CO2) in the earth's atmosphere caused by human activities such as burning fossil fuels and deforestation. When CO2 is released into the atmosphere, most of it is absorbed by the ocean, limiting the pH of the ocean and making it more acidic.
The pH scale is a measure of acidity or basicity with values ranging from 0 to 14, where 7 is neutral, less than 7 is acidic, and greater than 7 is basic. Ocean pH has declined by about 0.1% since the industrial revolution began. This may not seem like a big change even now, but it meant a 30% increase in acidity.
Chemical methods that cause ocean acidification include:
When CO2 is absorbed from seawater, it reacts with water molecules to form carbonic acid. Carbonic acid then dissociates, releasing hydrogen ions (H+) and bicarbonate ions (HCO3-). Hydrogen ions lower the pH of seawater, making it acidic.
Ocean acidification has many negative effects on marine life and ecosystems. It affects the ability of some marine organisms, such as corals, mollusks and some plankton species, to build and maintain shells and skeletons made of calcium carbonate. organisms become more difficult to absorb the calcium carbonate needed to build structures, which can lead to slower growth, weakened structures, and increased mortality.
Ocean acidification also affects the behavior and physiology of many marine organisms and fish, altering sensory systems, affecting metabolism, and altering the composition of food sources.
In summary, ocean acidification is a huge environmental burden caused by increasing atmospheric carbon dioxide concentrations. It has a wide range of negative impacts on marine life and ecosystems, and it is essential to reduce the greenhouse gas emissions of gasoline in order to gradually mitigate or mitigate these impacts.
