How ocean acidification could disrupt the entire food web, with dire consequences

What they (scientists) say is this: the oceans are 30 percent more acidic today than they were during pre-industrial times and, if we continue burning fossil fuels as we are now, we will double the ocean’s acidity by the end of the century. Scientists fear many organisms may not survive so radical a shift in chemistry. And some of those organisms form the foundation of ocean food webs. If they perish, what happens to the tens of thousands of species further up the chain? What happens to our shellfish — our oysters, clams, mussels — that appear particularly vulnerable to ocean acidification? VIDEOS, READ MORE….Sigourney Weaver: Protecting Our Oceans for Earth Day.
