Ocean Acidification — What's Happening to Our Seas?

Ocean acidification is a serious environmental problem caused by rising levels of carbon dioxide (CO₂) in Earth's atmosphere. As CO₂ dissolves into seawater, it creates carbonic acid, making the ocean more acidic. Since the Industrial Revolution, ocean acidity has increased by about 30%. This change threatens marine ecosystems around the world — including Florida's coastal waters and the Indian River Lagoon.
