Scientists have revealed that ocean acidifications brought about by climatic changes have created problems for aquatic animals, especially clams and sea urchins, as they are facing hardship in growing their shells. It is being expected that the scenario must have been the same in all Polar Regions.

It is being expected that there would be a reduction in seafood for humans, as it has been warned that mussels, oysters, lobsters and crabs are likely to be in danger, thus making themselves food for the predators.

The British Antarctic Survey (BAS) findings, which have been published in journal Global Change Biology, emphasized that an increase in acidic levels is thus having an adverse effect on the size and weight of shells and skeletons and the impact of this acidity is suspected to affect major marine species.

The major cause determined for the increase in levels of acid has been proposed to be greenhouse gases, including carbon dioxide. Several human activities result in emission of these gases, which ultimately end up dissolving in ocean waters and thus increasing its acidity.

As a result, the marine creatures find it hard to obtain calcium carbonate, which is necessary for the growth of their skeletons and shells.
