Corals make their skeletons out of calcium and carbonate ions from seawater, constructing massive colonies as large as cars and small houses. As the ocean absorbs excess carbon dioxide from fossil-fuel burning, it spurs chemical reactions that lower the pH of seawater, a process known as ocean acidification. The process removes carbonate ions, making them less available for corals to build skeletons.

Can Underwater Parks Protect Coral? - Video
With global threats like ocean warming and acidification, it's a tough
time to be a coral. Marine scientists John Bruno and Elizabeth Selig, of
the University of North Carolina at Chapel Hill, analyzed over 8,000
coral surveys from all over the world to see if local management through
Marine Protected Areas had any positive effect on coral.
