An article like this came up. The topic is likely to be controversial, but it still has a direct relation to the chemistry of seawater... The Pacific Ocean is becoming acidic. Scientists have confirmed computer modeling data indicating that the acidity level of the Pacific Ocean has increased over the past 15 years. Researchers claim that at depths of 3-5 kilometers, acidity remains relatively constant, while closer to the surface, at depths of up to 700 meters, it is rising rapidly. Carbon dioxide dissolves in ocean waters and alters their composition. Thus, the world's oceans are slowing down the process of global warming. However, the increase in water acidity poses a serious threat to marine life. There may come a time when the formation of skeletons for certain species of animals becomes impossible, as carbonic acid will begin to dissolve calcareous structures. This primarily concerns aragonite, the most soluble form of calcium carbonate. Calcareous shells of pteropod mollusks are made from it. It is possible that this type of invertebrate will become the first victim of the increasing acidity of the world's oceans.
