Ocean acidification involves the ocean’s pH, changes in which make the water become either more alkaline or more acidic. Tests have shown that “for more than 600,000 years the ocean had a pH of approximately 8.2.” But since the industrial revolution, the ocean’s pH has dropped by 0.1 unit.
CO2-caused climate changes have already made the planet’s food shortage worse. Over the next three decades, climate changes will make it still worse. These shortages will be further exacerbated by the reduction of seafood because of CO2-caused ocean acidification.
