Ocean acidifcation resolution needs support

Posted: March 29, 2011 - 8:46pm

I would just like to inform the general public of the rising issue of ocean acidification, and the legislation that is currently being discussed on it. Ocean acidification is caused by excess carbon dioxide being absorbed into the oceans from the atmosphere. The carbon dioxide then mixes with the water molecules and becomes carbonic acids. These acids cause calcium carbonate, a chemical compound needed by crustaceans to develop healthy shells, to diminish. Ocean acidification has caused a 30 percent increase in the acidity of ocean surface waters since the start of the Industrial Revolution. This has caused some planktons to die because the acidity is breaking down their shells and then wearing down their bodies. If this trend continues, there could be a drastic decrease in the plankton in the oceans, causing salmon populations to drop, and end thousands of Alaskan jobs. There is currently a resolution in the state Legislature supporting research of ocean acidification, and recognizing it as a threat to our Alaskan way of life. If you too believe that ocean acidification is a major issue that our state needs to be more accountable about, please contact your legislators and urge them to vote yes on House Joint Resolution 10.
