Captain Cook’s Crabs

Good article on the plight of Dungeness crabs (“Feeling Crabby,” 9/5). One footnote I would add is that Captain Cook noticed dead zones off of our coast in the 1700s.

Climate change may be making them worse along with industry caused acidification. But there are many natural causes as well. Possibly the volcanic action we are seeing plays a hand.
