Ocean acidification causes a decrease in the pH concentration of the oceans, mostly arises as a result of the entry of carbon dioxide from the atmosphere.

50. because its 140 in 1991 and about 90 in 1992.
Since chemical spills are very harmful to aquatic/land life for both plants and animals, plants probably wouldn't grow back and animals could be mutated or even killed, decreasing the population of that species.
