If Money Talks, Maybe It’s Time to Give Ecosystems a Voice – March 28, 2013

Even so, more than 85 percent of oyster reefs have disappeared worldwide due to overharvesting, dredging, pollution, and disease. Oyster populations in the Gulf of Mexico, for example, have suffered a full century of decline. Native oyster beds there received sparse attention and few protections — until Hurricane Katrina, that is. Then suddenly policy makers and members of the public were clamoring to know more about what the oyster ecosystem was worth.
