Thanks Jim, didn't see the biochar thread before your advise. I had heard of it, and find it a very interesting issue to study. But there Bruce comes and tell the truth about where are the main problems we find. Laws and taxes are designed for industrial production.
Small is beautiful is not compatible with such a design.
About the 'isolated group of people' that Bruce said, yeah, sounds Amish, and I pretty much dislike the religious idea. Just take religion out and it might work. Or not!?
A few years ago there was a study about how kibutz did evolve in Israel. It was interesting and focus in human relationships. It was published in a psychology magazine. (sorry again, I don't have the source, but the magazine is from Scientific American editors, called in Spanish "Mente y Cerebro") The kibutz could well be a kind of Bruce's proposal, not forgetting that their intention was not to cut emissions, it was just a matter of idilic survival but had the 'isolated group' coincidence.
What they found was very interesting. There were basically 2 kind of kibutz: the lay-kibutz and the religious kibutz. The lay ones were formed mostly by hippie type people and the religious ones were formed by strict Jewish orthodoxes. The study was done more than 30 years after they started and did show that almost all the lay kibutz had collapsed while the religious ones were still going on.
Why? They found that lay ones had suffered from social instability from the very beginning, something that did not happened in the religious ones. They could explain this saying that in the lay groups there were people who's intention was to live from the others, not willing to share hard work or restrictions imposed by the events. This kind of parasitic behaviour was poisonous enough to break social equilibrium and end up in factions and conflicts.
In the strict religious groups unity and cooperation was the rule and there were no parasitic members because, to start with, no one of this kind of people would like to join a group of people where social rules are so strict.
So back again to the simple theory. Is a matter of symbiosis instead of parasitism.
I would like to share more time with you guys in this forum, but it's difficult to find free time, or not to be too tired to try to write in English.
