Well I guess my only real problem is the group assessing the value is not government backed and as such may not have strict enough guidance when determining impact. However the need for assessment if there is a reasonable means to correct the issue or prevent future occurrence. I doubt we can correct it and do we know if this has ever occurred without possibility of man's activities? I would be curious as to the evolution of coral reefs, what is their historic variability?
