William the problem with your analysis is your assumption that all existing
coral reef damage is due only to the coral trade. Where is the empirical
evidence for this?

The other problem is that you are assuming that every aquarium contains
nothing but wild collected P corals, when in reality I would argue that
most contain mainly F1 and even F2 or higher propagates, especially when
dealing with branching species such as Acropora.

Your formula is an over simplification of the issue.
