[Coral-List] Listing Criteria Observation

You keep referring to the tragedy of the commons dilemma. One particular
case of this was our early settlers. They almost didn't make it due to
public ownership of land and resources.
How did they fix it? Elinor Ostrom suggested that non local or gov.
Intervention would worsen this problem and that local people are better
suited to solve this. Mariculture is a great means towards sustainability
for the aquarium trade and for the indigenous people. What I fear is that
regulations such as these cause problems down the road when more species of
coral die since the ocean is in decline as a desirable coral habitat. That
is, more regulations because the first round didn't work. This is always
how gov. Operates. It never gets rid of regulations. Plus, how will the gov
ensure that no banned species are in aquariums after the ban? What about
pre-ban acquisitions? Will it be illegal to possessing them? If so, I am
throwing my stuff in the Atlantic. You see.... There are many externalities
that would arise. Gov. Good intentions usually produce bad results.
Anyone know the answer to this?
Is Apal and Acer on the rebound since being listed? If the FL Keys were
suitable for them to thrive they wouldn't need human help via propagation
once banned from harvest. They would thrive beyond belief. Much like a
nuisance coral in an aquarium that is left un-fragmented. Unless I inject
one of the man made problems we can't seem to agree upon as the main
problem for reefs declining.
I believe there is no regulation or cultural change that is on the live to
slow the decline of our reefs. Even if there was, it would still take a
decade or more to see any positive benefit. If I am right, choose your
regulations or education of people wisely.
