I remember some years ago reading that the “crown of thorns” starfish would be the inevitable death of the coral reef. It eats the living coral and leaves the bleached skeleton behind. People actually had a big project to kill the starfish, but they were so numerous it was a losing battle. Problem was, the crown of thorns’ main predator didn’t seem to be showing up. This article does give a nod to the high numbers of crown of thorns starfish in this particular segment of reef. (which are eating live coral or they wouldn’t be there)
And this segment of the reef, we’re told in the article, is opposite a large Australian port, and is frequented by lots of tourists. Of course, effluent from the port and petrochemicals from the boats couldn’t possibly have anything to do with the toll on the coral. Oh, and as we know, crown of thorns starfish proliferate when nutrients like fertilizer get into the ocean. But the writer of the article didn’t look into that. Apparently, now and then, those starfish will denude 90% of a coral reef if the nutrients are there for their polyps to feed on, and if overfishing reduces the few predators the starfish has. Possibly Australia ought to look at effluent, fertilizers and overfishing by all those tourists.
Nope. It’s MMGW.
