What is the primary cause of ocean acidification?
Answer
Increased CO2 absorption
Ocean acidification is caused by increased atmospheric CO2. When seawater absorbs CO2, it forms carbonic acid, lowering the pH and threatening shell-forming organisms.
💡 Did you know?
Ocean pH has dropped 0.1 units since pre-industrial times, representing a 30% increase in acidity—the fastest rate of acidification in 300 million years.
