Ocean Acidification has been an acknowledged problem in Florida’s waters since the late 1990s. It’s caused by cement production and the burning of fossil fuels. Those emit carbon dioxide into the air, and it builds in the atmosphere.
Carbon dioxide is a greenhouse gas that causes global warming. And about a third of all that CO2 dissolves into the ocean, causing Ocean Acidification. It actually changes the chemistry of the water, and has negative effects on the organisms living in it.
