Scuba diving is a non-factor compared to global warming...

As a diver who does, in fact, travel, I have to point out that the issue of diver damage to reefs is only a small part of the problem. Remember, divers do not visit most of any reef. I'll give you that heavily used areas suffer, but they are a small fraction of the reefs that are being lost.
Further, don't (confuse) ecotourism with other development issues. Scuba divers make up only a very small fraction of the visitors driving development. Cozumel did not dig up part of Paradise reef to allow more divers; rather the cruise ships that have become the major economic engine for the island.
You simply cannot ignore the much greater impact of pollution, waste water management, agriculture, and warming oceans and say that diving is the cause.
