User blog comment:Fliu/My thoughts on the Fishman Island arc/@comment-1595565-20111208232547

Good wrap up. I think Shirley's prediction is meant to be taken metaphorically. Luffy didn't destroy the island, obviously. What he destroyed was the old relationship between fishmen and humans. It goes back to when Fukaboshi asks Luffy to "bring them to zero". Tear down the old ways, and start a new culture where there isn't that hatred. I think that's what Luffy did. As for her vision, a lot of dust was kicked up during the fight in the plaza, so it could easily have just been that.
