"EPA Tells States To Consider Rising Ocean Acidity"

"SEATTLE -- States with coastal water that is becoming more acidic because of carbon dioxide should list them as impaired under the Clean Water Act, the U.S. Environmental Agency said.

The federal agency's memo Monday to states recognizes carbon dioxide as not only an air pollutant but a water pollutant, and notes the serious impacts that ocean acidification can have on aquatic life.

Ocean acidification refers to the decrease in the alkalinity of oceans, which is caused by the absorption of excess carbon dioxide from the atmosphere. As water becomes more acidic, scientists have raised concern about dissolving coral reefs and potential effects on fish and other sea life."
