How do you think ocean acidification will affect coral reefs?

Explanation:

The rising acidity of the oceans threatens coral reefs by making it harder for corals to build their skeletons. ... Corals grow their skeletons upward toward sunlight and also thicken them to reinforce them.

Ocean acidification (OA) is considered an important threat to coral reef ecosystems, because it reduces the availability of carbonate ions that reef-building corals need to produce their skeletons.
