I worry about red tides, and pollution in Cape Cod’s murky waters, sometimes called dark water. It hasn’t been killing whales yet, but can we imagine a scenario where creature death pollution creates such murky waters that all the whales die, and the rest of parts of the ocean. It is of no doubt that global climate change is probably a problem, as well as shellfishing. IMHO we need to stop eating shellfish. It is filtering the nastiness out, eating it.
If nastiness gets too bad, even clam beds become polluted ~ “red tide," but everybody has heard of that.
Are we ready for:
Mass cataclysmic death of most ocean life.
