Time Lapse of a Sand Dollar. {Video} ~ Dareni Wellman

The ocean absorbs about a quarter of the carbon dioxide released into the atmosphere a year.

With levels of CO2 steadily rising each year, the oceans are becoming more and more acidic. This increase in acidity has profound effects on the environment, including the dissolving of calcium marine creatures like coral and sand dollars.

Check out this video from scientist Cassandra Brooks, a marine biologist who is working to inform the community of ocean issues.

This video is a time lapse of a sand dollar exposed to high acidity. Watch what happens.
