[Coral-List] Why we are failing to repair coral reefs

Energy units and land requirements to support an individual are dynamic and have changed a lot over time with advancements.....no?   I know a well known ecologist who calculated the earth population explosion back in 68 as well.    None of it has yet come to pass.....because advancements intervened.  I hear what Francesca is saying....and I too am an optimist.  

Ps. When the world had 3,5 billion people it was the 60s I think.  Id say we most certainly did have environmental catastrophes then. Go back even farther....Hanford.... Love canal,  bikini atoll.....WWII.  If you think the Iraq war or the BP spill were big, they don't hold a candle to WWII.  

Thanks for the provocative discussion

It has been calculated by a number of well-known ecologists based on energy units, how much land it takes to support a person's needs (while still leaving land for wildlife), and other ways.  Richard Leakey quoted that number to me a few years back when I asked him the question.  I have seen it explained in a number of publications (check out that book I recommended awhile back "Life on the Brink").  Yes more people can live on Earth (and currently do) but at the expense of the environment (including climate change and coral reefs).

Coral reefs are just one of many ecosystems on Planet Earth that are in distress and being wiped out systematically due to the human cancer:  forests (rain and temperate, and all other kinds), wetlands, tundra, coastal plains, estuaries, and on and on.  We can't hope to save one without saving them all, and to do that in the long term, we have to somehow reduce human numbers to half of those inhabiting Earth today.  It may be too late already, but the longer we wait to even recognize the root of the problem and get moving to do something about it, the less likely that this will happen in time to save the organisms and ecosystems we know and value.

> Hi,
> I recently penned a comment on why we are, for the most part, failing in our efforts to repair and sustain coral reefs, despite the efforts of many dedicated and hard-working people.  It appeared in Reef Encounter, the on-line news journal of ISRS, and many readers of this list will have seen it already.  Thinking it might be worth wider dissemination, I've now put it up on my blog, with some pretty pictures attached.  You can access the blog at www.petersalebooks.com/?p=1708  and you can see the original in Reef Encounter which can be downloaded from the ISRS website at http://coralreefs.org/  Reef Encounter has lots of interesting content (perhaps even more interesting than my comment)!
