Believe it or not, snail-like sea creatures are vanishing in a part of the Southern Ocean due to the human-caused carbon dioxide emissions. Scientists have already predicted that a group of tiny snail-like sea creatures crucial to the marine food web may one day disappear due to the changing ocean chemistry.
Now a new survey conducted by Geraint Tarling and his colleagues of the British Antarctic Survey in Cambridge concludes that the corrosive seas are damaging pteropods much before than expected.
The high amounts of man-made acidification lead to the shell loss of the snails in the South Atlantic Ocean. As deep frigid water normally contains more carbon dioxide, its pH is naturally lower than that of surface waters.
Recent researches prove that the change is actually taking place much faster than expected. In the acidification process, CO2 air pollution works in the water to form carbonic acid that dissolves the calcium shells of sea snails and other mollusks. Consequently, they get exposed to acidification.
The possible solutions for this ocean acidification include frantically dumping large quantities of limestone in the ocean.
