Esej o Ocean Acidification and Its Threat to Marine Food Chains - 263 slow

The Chemical Shift of the Global Ocean

The global ocean acts as a massive carbon sink, absorbing nearly thirty percent of anthropogenic carbon dioxide. While this process mitigates atmospheric warming, it triggers a chemical shift known as ocean acidification. When CO2 dissolves in seawater, it reacts to form carbonic acid, which subsequently releases hydrogen ions. This reaction lowers the pH level of the water, fundamentally altering the environment for all marine life.
