Aloha Karl, thank you for the clarification concerning Vanuatu coral
Just to clarify, to me the term "chop shop" refers to the practice of
removing entire coral heads, fragmenting them ex situ and discarding the
remains. Hence the term "chop shop", which refers to the practice of
completely dismantling an entire stolen car for its parts, which are
then in turn sold. I would not classify what you describe as "chop shop"
behaviour. A more apt analogy might be removing the headlights or side
mirrors of a car; parts that can be easily replaced, or better perhaps,
cutting a lawn or trimming a bush. One can argue the merits of the
latter practice but I believe its potential environmental impacts are
much less given the rapid regrowth of the "donor" colonies, which I
believe you were responsible for tracking at the time. Do you have
documented evidence that this practice is then "unsustainable" and what
definition of "sustainability" are you using? Given the sheer surface
area of reefs along the coasts of the islands in Vanuatu and the small
scale operation there, I find it hard to picture this practice having
substantial long term negative impacts.
