Acidification is a threat our ocean faces. It happens due to the ocean absorbing more carbon dioxide (CO2) then it can take. This increases the acidity level. In the last 200 years, our ocean has become 30% more acidic due to increased CO2 levels. An increase in acidity effects marine life and has caused coral reefs and creatures with shells to starting dissolving.
