The rate of ocean acidification is expected to accelerate in the near future. Since the industrial revolution, ocean acidification has increased by 30%. Scientists believe that this rate is faster than anything previously experienced over the last 55 million years.

The problem is that even a mild change in PH levels has significant impact on animals with calcium carbonate shells or skeletons. They literally dissolve. Affected animals include krill and plankton as well as coral. This means that the bottom of the food web could potentially become extinct, and in turn so could fish, according to Zoologist Kent Carpenter: "If corals themselves are at risk of extinction and do in fact go extinct, that will most probably lead to a cascade effect where we will lose thousands and thousands of other species that depend on coral reefs.”
