... on the saturation state of calcium carbonate in surrounding surface waters. This saturation state declines as the CO2 enters tropical surface waters. Burning coal, gas and other fossil fuels causes carbon dioxide, and it threatens the existence of the reefs. As CO2 dissolves, it produces an acid that lowers the seawater pH. The interaction of ... ! carbon dioxide with calcium carbonate in seawater decreases the level of calcium carbonate saturation (Fenner 166). This in turn will not allow the reefs to grow and will become fragile. If these ... ...
