      No worries, new is great. “previous answers” often do provide additional insight and different references. Keep doing what you’re doing.

    As CO2 concentration rises in the atmosphere, oceans absorb more CO2, and become more acidic.  This affects all mollusks, because they can’t form strong shells in acidic environments.  Mollusks would adjust, given time, but the rate of ocean acidification is unprecedented, and evolution rarely works on short time scales.  Mollusks are an important part of the ocean food web, and their capacity, as filter-feeders, to purify water is critical to the health of coastal estuaries and fisheries.  

    But mollusks are only the most obvious victims of global warming.  Global warming is changing temperature gradients in ocean waters, increasing the range of some species, while decreasing the range of others.  We’ve selectively and very efficiently killed off the top of ocean food chains, taking large numbers of tuna and sharks. We are creating an ocean paradise for squid, so start collecting recipes for calamari.
