It goes like this: You dump the inkwell (toxic discharge from industry and sewage systems) into the goldfish bowl (ocean) and the fish all turn belly up and the bowl is without fish.

I suspect that none of the researchers whose work was described in this article was ever a teenage girl with an absent (or distant) father.
