CO2 in Oceans

The amount of CO2 in the atmosphere increases, and much of this gas is absorbed by the oceans, the sea water reacts with carbon dioxide forming carbonic acid, which causes an increase in the acidity of the seas.

The more acidic areas are mainly the polar seas and deep waters, over time this situation can go to the tropics and start a reaction with terrible consequences.

Problems:

- A more normal acid can be harmful to some marine organisms, which can have bad consequences for the marine ecosystem, especially for organisms such as corals and mollusks for those shells, clams, turtles, snails, and crustaceans ... as the speed at which they produce their shells will fall between 25% and 10% respectively.

- Plankton can also fall into this situation, causing damage to the first links of the food chain from the sea, which may change the overall balance, as many organisms are eaten by fish and marine mammals.

- The larvae of most fish and marine organisms find their way to their habitat by the smell. In laboratory experiments, in waters with an acidity equal to the calculated for the end of this century, the larvae fail and can not find the way, since the acidity prevents them from finding the right smell.
