How does it affect the CO2 to the sea?

As the level of dioxide of atmospheric carbon increases, not only the planet warms up, but on having dissolved in the oceans, it turns more acids. For the animals that are protected by shells it generates a corrosive and even mortal environment. The oceans are a natural way that favirece the accession of CO2 and they have absorbed more of fourth one part of what has been liberated in the atmosphere. Nowadays the human beings we generate too many CO2 of which the oceans receive 25 million tons a day. The scientists have detected an increase in the acidity of almost 30 % in the superficial waters and predict that there will be an increase from 100 to 150 % at the end of the 21st century.
Till now effects have not received documents in the open sea, but the threat is evident. On having been absorbed by the water, the CO2 reacts and forms carbonic acid. During this process, less and less ions of carbonate float around, which is harmful because many organismsof the sea depend on the carbonate of the marine water for the formation of hisshells.
Some models for computer predict that in 50 years the polar waters will turn hóstiles for the mollusks with shell About 2100 the habitat of many marine species of shell might diminish drastically, which would reverberate in the nourishing chain of the sea.
