The Great Barrier Reef has been around for something over two million years. Since it began growing sometime after the break up of the super continent, there have been several periods of glaciation where the sea level fell and the reef died followed by rising sea levels and new reef building.What lessons can be learned from the Great Barrier reef?

some enlightenment about what we might be able to learn from something that is a relatively continuous record for more than 2 Million Years. I wondered if it was another correlation method and just what it showed.Whatever's contributions, here or in every other thread were he has posted, have simply been childish stream of conciousness showing absolutely no informational content, no capability to understand even basics, no willingness to learn and an absolute propensity for utter foolishness.Unless he can add information to the discussion there is no reason for him to participate. If that kills the line of discussion, then I will simply persue other avenues of research.
