    How does that compare to the quantity of sand already in existence? There was a long period of time (millions and millions of years) when there were no parrotfish, but billions of tons of calcium carbonate being eroded by the weather.

    I didn't read it as bickering at all, just two people with an interest in sand, trying to get to the truth.
