The evolutionary pressure to cause a mutated, plastic-eating fish to outcompete non-plastic-eating fish would suggest that there would be areas where plastic was more abundant that the other things (plankton, mostly) that fish normally feed on, i.e. other fish would be at a disadvantage because they couldn't process plastic. That's a pretty dire scenario for humans.
