With regard to what appears to be your underlying assumption here that a 7+ billion world population is sustainable long-term, if we'd just 'figure out how to do it' - here are a couple of things that might be worth considering:
a) If it's physically possible for the planet to sustain such a population, why, pray tell, has it never (at least as far as we know) even remotely approached that level prior to the widespread technological exploitation of hydrocarbon fuels? Two words that might suggest an avenue for considering this particular question: 'Green Revolution'.
You seem to me to have the cart before the horse. Placing them that way predispositions the outcome to of the discussion to failure to even look for additional avenues and alternatives to the predisposed ideas we have been seeing for 40 years now. That tactical argument is used by everyone defending the status quo of every "established theory" existent.
Try just once saying it another way.. We do not (because history is in fact simply a collection of local remembrances and not yet fully cohesive even today in the age of the INTERNET) know how many beings have inhabited the earth as a maximum number. Now that statement cant be argued with facts.
We do have a pretty good idea what the sustainability is of our present social structure and technological base, BUT we have no knowledge preventing some other technology or even cohesive understanding of other life styles from achieving a sustainable ecology with any given number of people not based on observations limited by the existence of this social structure we inhabit.
If we admit we do not know what the carrying capacity of the planet is, why should we assume that given a reasonable effort to correct the obvious faulty technologies/lifestyles we are using now we cannot continue to carry the number now existent?
If we wish to carry the number existent we can determine what technologies are in fact working for resource depletion, and what possible avenues of change can be found to correct those deficiencies. Once understood we should be able to design a remedial life and technology adapting the existent structures to ease the transition.
History is full of failed ideas, wars, pestilence, indifference ( oh wait that one is approaching again ( pick any of the for-mentioned).
But history also is a study of mankind's attempts to correct deficiencies overlaid on the the platitudes and chronicling of the rich and powerful.
$this->bbcode_second_pass_quote('TWilliam', 'b')) Can't remember where I first heard (read?) about this particular idea, but I came across it awhile back and it definitely gave me pause for thought. Consider the fact that, at least in any effective sense, there is a finite amount of biomass upon this planet. The more of it that gets converted into human bodies, the less of it there is to be utilized by everything else. What implications might this have for the biosphere at large, and its ability to sustain us?
I agree there is a finite amount of bio massive material building blocks, but cannot see any possible proof anyone might have tried to propose that the present population has used so much of those building blocks that there is not sufficient remaining. Please give more precise details on that?
My underlying point.. that billions of human beings each as valuable to the cosmos as any other deserve the maximum effort to find a way to preserve and augment their existence rather than a constant refrain of "it cant be done" and retreat to your redoubt and the devil take the hindmost I see so often.
A cockroach is a primitive form of life existent unchanged since the age of the dinosaurs, as it dies it lays eggs to hatch in 14 days as a continuation of it's life purposes. Ecovillage for the few kind reminds me of that. An old idea for those who have given up on creating a better world for all.
