probably, eh?
I wonder how much human feces it tales to amount to that of all the creatures in the ocean.
"Health of the coral reefs" indeed.
It's not the "whole" ocean. What's happening in many of these countries (particularly island nations) is that concentrated sewage outflow is getting dumped directly on the reefs that lie right offshore the coasts. This is a lot more waste (and nutrients) than are produced by the aquatic inhabitants of the reef themselves. Corals need very clear, low-nutrient water to survive, and the input of untreated sewage right on top of them is obviously not good.
