Overfishing is being blamed for the overgrowth of coral killing algae, but most of the coral killing algae has terpenes that fish usually don’t like. Sounds like back to the drawing board to me. Of course to people, coral is much prettier than seaweed, so naturally coral gets the cheers. Good thing for coral that fish don’t eat much of it, if any.
Most of the human (commercial) fishing is much farther north.
