[Coral-List] Replying to Peter Sale Coral Restoration

I think you make some excellent points and surely many coral restoration efforts are providing valuable insights into how we can regenerate reefs damaged by local and/or global stressors. The specific project you pointed out (Fragments of Hope) is a prime example. My concern (coming from a non-scientist) reflects one of the points that Peter made in his blog and that is that unless we address carbon levels directly (along with the usual lineup of local suspects) all these good works may be for naught. Just how resilient and adaptive can corals become? This doesn't suggest that we should forsake these efforts, but we should perhaps be mindful of their limitations. One concern that I have is that coral restoration is being used by some as a reason why we need not be overly concerned about coral reef degradation. For example, this line of thinking has entered into the debate about Grand Cayman's consideration of a new cruise ship berthing pier. Proponents argue that even though a popular reef spot will have to be sacrificed, science-guided restoration efforts are capable of rebuilding it and therefore we can have our cake and eat it too. I guess that the same can be said of concerns relating to the impacts of rising ocean temperatures and acidification. We can engineer our way out of it and restore our reefs as if nothing has happened. Although this is not the intent of the dedicated scientists who are working on these projects, we should be aware that misrepresentations abound.
