Shell Shifts

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity. The more acidic the ocean becomes, the harder it will be for certain animals, like shellfish, to form their shells. In this science snack, you'll see what happens to shells in highly acidic liquids.
