Thanks, Jamey, for the really informative overview.

I'd just want to underline the fact that the greatest threat to coral globally is climate-change. At reefs I have visited over a more than 40 year period in the Andaman sea and off the coasts of Indonesia, the effect has been horrifying. Just a couple of degrees increase in the water temperatures can lead to bleaching and extinction. I have scientist friends in both places who are trying to regenerate and even rebuild reefs, but the process is costly and often disheartening. The solutions ultimately will have to be global, not just local.
