[Coral-List] Reassessing Coral Reefs

You guys are getting depressing:)
Look at the list again: how many of the top 10 can any individual impact? Answer: none. When I try to explain threats to reefs to people, I try to break them into external threats - climate change, etc., that we can't do anything about as local managers, and the local threats - diver damage, trash, sewage, etc., that we CAN do something about as managers...working with the dive industry.
I do get it: diver damage affects a small amount of reefs worldwide. But it affects valuable "revenue reefs" that dive centres rely on.
Surely, it should be in the interests of the dive industry to do what they can to save those nice bits of reef for their customers. And in doing so, is there a slight chance that we may be able to persuade some of those interested, informed and motivated divers to stay at resorts with proper sewage treatment? Oh, and good waste management practices? And with snorkelling guides that don't feed fish? And is there the slightest chance some of that might spill over into the rest of their lives? Call me naive and idealistic.
Anyone from PADI reading this? Can you spell "dive centre adopt a reef" programme?
This is why I think mobilising the dive industry to do something to save "revenue reefs" could have wider impacts. And maybe involve some of those same people in monitoring and helping to gather the data everyone keeps telling me we don't have. To try to bring it back to coral list interests...

The reason for this in the diving community is really no different than in society at large. For example, how many patients question their doctor when he tells them they should stop smoking, exercise and eat a healthy diet? Virtually none because there s no large commercial interest that has anything to loose by this advice. (Big tobacco gave up years ago.) We now have the same scientific confidence about climate change as for any public health policy involving CVD. However, climate change flies directly against the interests of many big-time commercial interests, so like tobacco once did they have done all they can to muddy the water.
As you know as a dive center owner, there are lots of red meat tea baggers in high levels of our industry. So do the math. It may be different outside the US and I hope it is but I don t believe we ll ever see any real levelship from the dive community on the climate change issue. If one does develop, it will come from the bottom-up, not top-down (couldn t resist the coral reef reference).

> Doug is right on point as usual. The only thing that I might add is that it is very curious that the dive industry is science-oriented on so many of its principle teachings and beliefs. We embrace physics (pressure and depth , squeezes and the bends), chemistry, (nitrogen absorption, oxygen toxicity, Nitrox and Trimix) and even touch on marine biology. But when it comes to climate change, warming oceans and acidification there is suddenly a rejection of the prevailing scientific thought and assumptions. Hmm, I wonder what could possibly explain this peculiar inconsistency?

>> My memory is that Steve has been concerned for some time that the dive industry has done nothing to support action on climate change. They seem to show no interest. Steve's interest in climate change is because it is the 800 pound gorilla in the corner. If we don't do something about that, the reefs will be damaged far more from that than anything else. I agree.
>> I think we've gotten off the topic. But it does reflect what divers think. When they think of damage to the reef, they think, "divers damage the reefs." Most divers know that at one time or another, they've kicked a coral or grabbed hold of something, and many of us have seen anchor damage, and/or too many dive boats tied up to a float. Working on reducing diver impact does help the places where lots of divers dive.
>> However, this misses the big picture. What are the major threats to coral reef in the future? Sorry, but diver damage isn't even on the list of the top 14 threats NOAA reviewed threats to corals in its "Status Review Report" as a basis for making its decision on whether corals were endangered. They came up with a ranking similar to that done in the "Reefs at Risk" project. The 19 risks they evaluated and their evaluation of the level of risk are as follows:
>> 1. Ocean warming
>> 2. Coral disease
>> 3. Ocean acidification
>> 4. reef fishing-trophic effects
>> 5. sedimentation
>> 6. nutrients
>> 7. sea level rise
>> 8. toxins
>> 9. changing ocean circulation
>> 10. changing storm track/intensities
>> 11. predation (think crown-of-thorns starfish and Drupella snails)
>> 12. reef fishin- habitat impacts/destructive fishing 13. ornamental
>> trade 14. natural physical damage (think storms like hurricanes, and
>> tsunamis) 15. human-induced physical damage 16. aquatic invasive
>> species 17. salinity 18. African/Asian dust 19. changes in insolation
>> Diver and snorkeler damage are included in number 15, along with coastal construction and ship groundings. They don't say what proportion of human-induced physical damage they think diver damage is, but it appears to me that if it was by itself, it might not rank in the top 19.
>> We can argue about the rankings, but I think the message is clear, reducing diver damage is helpful to the reefs that are heavily dived, and so to dive operations. But divers dive on a tiny tiny fraction of the world's reefs, and compared to many other things, is a very minor, even negligible effect effect on the world's coral reefs.
>> Net effect is, working on reducing diver damage is re-arranging the deck chairs on the Titanic. Reducing diver damage is good, but it is a drop in the bucket. If we don't solve the big problems, reducing diver damage will not save reefs, in fact they will die anyhow. Bleaching alone killed about 16% of the world's reefs in 1998.
>> I think we're back to where Steve and I started at the beginning of his concerns, many months ago. The dive industry needs to speak up saying that humans need to switch to renewable energy sources, as well as advocate for tackling the main local threats: sedimentation, nutrients,overfishing, and disease. Mind you, we have little idea of how to tackle disease, except to reduce stresses on corals, including the high temperature events that often lead to disease events. But no one ever said it would be easy.
>> But apathy seems to reign supreme in the dive industry, and the few that are concerned are focusing on one of the most minor threats: diver damage. Well worth doing for the high-value reefs divers dive on. But won't do a thing to stop the decline of the world's reefs, sad to say. Unless, somehow, instilling a conservation ethic in divers can be used to lead to a desire to get out political leaders to tackle the big issues that really will make a difference. Maybe that's our best hope???

As for feeding, I've always been opposed and now the shark feeding craze has captivated the diving industry which sees it as a way of adding a much needed extreme edge to the "sport". In fact, there have been a number of scientific papers that seem to encourage the practice. It is clear that it won't be easy to gain universal consensus on a set of acceptable diving standards, but we must try hard to get the point across that coral reefs and marine life in general are in a critical phase which is very much dependent on human behavior and interventions. I hope that there is both the time and inclination to get this right.
