Actually, I wasn't referring to an individual school of fish, but was using the singular to try to illustrate a point. It was a lot easier than trying to refer to multiple schools every time.

I disagree with you about the global warming, but I think that you made a valid point when you pointed out that the fish congregate where the food is and then asked the question where would they go. This was one of my points as well when I pointed out that they could be attracted from one place to another. I don't deny that various places may be overfished, but I maintain that it is a stretch to say that we have lost 90% of the world's large fish.

I think it that It is obvious that we aren't going to convince each other, so what say we agree to disagree agreeably?
