Interesting Essay! As a believer of the Mother Nature concept along with Gaia, the most belligerent and destructive species walking the planet is the modern human. Human population is affecting the planet in a most spectacular manner - in a negative way that is of course. We can look at human history and whenever the population gets high we compete nationalistically for natural resources that often end as shooting wars and the resultant population reduction of those same ethnically diverse & nationalistically motivated embattled competitors.
With the way the World is now evolving, those days of natural resource competition have started to become more and more acute; week by week. It appears the EU is to rise as the most dominant Western block that is now even competing with the rising Asian Block led by China. Will the EU or China care about coral reefs when it comes to keeping their populations satiated with consumables along with the glitter & glamor of technology.
Where does this all fit with coral reefs and biodiversity? It fits by the very fact that reefs worldwide are continuing to ecologically fail; some beyond any hint of recovery. Over population of the poor and 'those without' have dramatically increased nearby or even on those reefs trying to survive. My question is here, is when will these reefs reach a point of no return and abruptly collapse? Could it be like a marine aquarium collapse, whereas, once a level of death, coupled with aberrant environmental parameters reaching intolerable levels => the aquarium completely collapses / dies?
An example of potential reef collapse - that I have personally observed on the shallow reefs of Tawi Tawi, Autonomous Region of Muslim Mindanao - Republic of the Philippines - was in February-March of 2009. I was asked by USAID to assess the scenario for 'coral and giant clam farming.' After a week of diving and site assessments, it finally dawned on me that there was something wrong with the 'picture.' Understandably there was a lack of any large giant clams (Tridacna) but when I noticed in all the pictures that I took, and with all the diving I did => there were absolutely no sea cucumbers present on the reefs - none, nada! I asked in town what happened? Buyers from China and Taiwan 'bought'em all' - every last one. No preference for sizes or ages = > all were taken.
Every presentation I give about the future of Coral Reefs of the World, I stress the need for human population control! I stress mariculture alternatives to start to replace wild harvesting. I stress the need to change the lack of nationalistic willpower to care and 'see the writing on the wall.' I get arguments back that 'if we don't catch/take/harvest.... the others will...so we continue.'
Solutions? Solution by human kind? Perhaps Gaia will provide us a solution for us eventually? It won't be pretty for human kind either.

The Battle for Biodiversity
For hundreds of years, and into this century as well, we have selectively
exploited the resources of our marine environment striving only for
“sustainability”. And of course, to our simplistic and materialistic economic
philosophy, “sustainability” means to take every individual from every valuable
species that it is possible to take within the expectation that there will be
enough individuals remaining to assure that the same amount can be taken the
next year. And that, of course, is, or was, the philosophy of those concerned
about the maintaining an exploitable future for the resource. Those interested
only in the short term economic gain of unrestricted exploitation without
concern for the future of the resource, the environment, or the cooperative
human investment in the health of the resource, ignore and circumvent whenever
possible any conservation efforts that may be imposed to protect the resource.
My concern though, is not with the “outlaws”, but with the prevailing approach
to conservation of valuable species. In essentially all instances, the value of
biodiversity in not considered. The concept of protecting biodiversity in order
to sustain a healthy ecosystem is a relatively new and not well accepted concept
by most who rest their living from the resources of the sea.
A case in point is the spiny lobster fishery of Florida. It has been shown
through analysis of mitochondrial DNA (Silberman, et. al., 1994) that, as
expected, genetic analysis shows no evidence of genetic structure in the spiny
lobster (P. argus) population, which is consistent with a high gene flow
throughout the population. This also indicates that the population of spiny
lobsters in Florida is dependent on larval influx from Caribbean sources.
The response of Florida fishermen to the NOAA effort to utilize catch shares, a
method of regulating the total catch of a species to protect both the species
and their place in the ecosystem reflects the inevitable “tragedy of the
commons” result of economic based fishery management. The response of the
Florida Keys Commercial Fisherman’s Association to the status of the spiny
lobster population in the Keys is “We fishermen believe that in essence, we
could harvest every legal size, non-egg bearing lobster in Florida, and it would
make no difference to how many lobster we catch next year.” Which may be true,
and which makes sense within the age old concept of exploitation to very limit
of all economically valuable marine species, but it fails to recognize the great
damage this mindset does to the ecological health of marine environments.
Spiny lobsters are, or were, an important cog in the ecology of Florida coral
reefs and they are now, because of fishery exploitation, essentially no longer
ecologically functional on these reefs, or in the nursery areas of Florida Bay.
Marine Protected Areas are very important to the maintenance of essential
biodiversity in marine environments. But in the long run, unless the areas
protected are very great, that may not be a functional method to repair general
biodiversity. We are facing a crisis brought on by our exploitation of all the
resources of the earth, living and fossil, and the only real answers are
population control and development of a universal human mind set of ecological
preservation that controls all exploitation, placing the health of the
environment before the demands of economic and recreational exploitation. And
how can we accomplish that?
