Corrosion by water: snails are at risk more than anyone

Ask any student that looks like a snail, and his answer will begin with a description of the shell. Perhaps in the near future, this description will always remain in the past. Shells of marine snails rapidly destroyed by ocean acidification. The pH of water is now changing more rapidly than in any of the previous 300 million years.

A team of scientists at the British Antarctic Survey by Dr Tarling Gerenta published in a popular science magazine article in which scientists tell us that the coast of Antarctica, they have found a significant amount of free-floating empty shells, pitted corrosion. Owners of the snail shells Limacina helicina, apparently died because of the chemical properties of water. The sorry state of shells only confirms the terrible guess scientists.

From changes the acidity of water and the corals are suffering, and other shellfish, but that snails are at risk the most. According to scientists, in 2050, in some parts of the world they may disappear altogether. But their shells are an important element in the diet of many fish and sea birds.
