I bought a diving DVD yesterday and it sounds like I saw a lot of the same lack of respect for the reef I believe your picture shows (I haven't seen picture). I kept on getting pissed off at divers grabbing ahold of coral, seeing fins brushing against coral, and one shot where the diver was headed toward an overhang a bit high. They cut the shot just before the top of her head rammed the rock ledge. Obviously the rock ledge probably didn't care, unlike the coral, I just thought it was funny.
Oh, all along the music was saying "teach your kids..." in ref. to protecting the reefs.
