[Coral-List] Remnancy vs Resiliency: Part 3

Hi Phil & others:
I am the first to agree with you that human overpopulation, and all of our demands on the environment to support the number of people living today is the root of all 'evil', including over fishing of all marine (and terrestrial) systems, not just coral reefs. World forests are in far worse shape than coral reefs, dissappearing in %s per day and yet we don't do much about it Deforestation to clear land for farming, homesteads, and collect wood for building materials or making charcoal, is followed by soil erosion, and coastal sedimentation. Human needs for food and other commodities lead to over-application of fertilizer and pesticides; fossil fuel burning for modern industries and to support our fat life styles; not to mention religious and ethnic conflicts etc. Not just coral reefs but every marine and terrestrial ecosystem on Earth are being affected by human activity, and many such as tropical rainforests, much more than coral reefs! Think about all the big deserts we have created through deforestation. Every human living in the tropics and elsewhere makes their tiny daily contribution to environmental decline not just of coral reefs but of Earth resources. Look around you and notice how many additional wooded areas in your neighborhoods are being cut down for new developments, and the muddy runoff that seeps into local streams and coastal areas. I have been plugging a new book by Jared Diamond in which he recounts how past and present human societies have gradually over-exploited their environs to their own demise [book is titled: "Collapse: How societies choose to fail or succeed"]. Diamond expressed some hope for the future because he found a few examples where when strong leaders, or small cohesive communities, realized what was happening they were able to choose to take actions that prevented future decline and were able to restore their damaged ecosystems and save their societies. However, he presented many more case studies where such actions were not taken and where the socities ending up becoming extinct. So which way are we headed?
You ask for action and in the past few years, the President's Ocean Commission and the Pew's Ocean Commission both reported on and recognized most of the environmental problems above and that you stated in your email. It's not that people don't know what is going on, rather that there are conflicting views about the severity of the problem, and what can be done about it. Those two reports if you read them contain many of the measures needed to at least slow down some of the abuse of the world's oceans, but of course totally side step the human overpopulation issue. This is not a poltically correct issue to bring up in our polite society: you might offend someone who has 5 kids or 53 grand children... If we had strong leadership in our country we would expect to see something happening after the must publicized release of those two extensive reports with long lists of urgently needed action items [Side note: if you look though those reports, pretty coral reef photos abound in them]. I have not seem the US public beating down the doors to Congress making sure those action items are acted on! Why not?
China was criticized to high heaven for politically limiting human reproduction. In some parts of the world, people have self-limited family size, but in others 6 to 10 kids is the norm. We glorify in our newspapers that a 62 year old woman who gave birth to her 12th child! (recent article in US news). We don't help women in poor countries control their reproduction so that they fewer children that they can provide for better. We keep coming up with new treatments to reduce infant mortality so that they can survive to live a life of hunger and poverty and contribute to more environmental abuse and political strife.
For the first world folks reading this message, I would ask how many of you that clamor for more action be taken right now to save coral reefs drive an unnecessarily big vehicle? (not picking on just SUVs, but Hummers, giant pickups to take kids to soccer etc)? How many TVs and gadgets do you feel you must have? These are all life-style attributes we can chose to change, and if enough people do it, maybe we can turn things around. Unfortunately, people are selfish and few want to give up the better life we have built for oursleves this past century, and all those out there that don't have our modern, high consumption life style know about ours and want it too! Globally, things will only get worse over the next few decades.
So where are we headed? I don't believe in "sustainability" because it is a meaningless word the way people think about it, which is: ' if we could only find a way to continue to fish as much as we do now without affecting the fish stocks' [not close a fish stock, and in 20 years or more, fish 1/10th or less of what we take now]. Or cut down all the remaining old growth forests because we need wood now and replant with fast growing pines. Or pump more oil and gas and coal from our own lands so we are not beholden to other countries for energy because we have to support our presnet life style needs and a GROWING economy.
Going back to Diamond's book, I am less optimistic than he because (1) I see no evidence of strong or insighful leadership on the global scale needed to get us out of this pickle, and (2) human societies are too conflicted to make much of a difference with the bottom up approach.
So when we come down to ot, coral reef decline is the least of our problems, albeit one that readers of this forum hold close to their hearts. But as long as we continue to think about coral reefs as a separate special case of the continuum of nature, we will get nowhere. We are really fighting for the future of the human life-support ecosystem and it needs to be done at every local planning board meeting and in every choice we make. How many of us are up to that level of engagement? I know I am not doing enough or as much as I could. It's easy to sit here in my study and write this long diatribe about world issues and then go on with life as usual. I drive a Pruis but I am surrounded by electronic gadgets I'd be hard pressed to live without.
So, we can continue to fret about resiliency, remnancy, vitality indices etc, but as long as we don't connect the dots all the way to the top and start problem solving there, all we are doing is venting our frustrations with being part of the bigger problem.

Coral reefs are not dying all over the world. We have 1000's that
are very healthy in the Pacific, not to say there are not problems but it
doesn't help to make sweeping false generalizations.
