In it, you would be able to produce everything you need at whatever level the circle operated (on your property, in your neighborhood, in your town, in your bioregion, and on up), without any necessary imports. And you would simultaneously grow enough resources to replace everything you consume - fertility, soil humus, natural resources. And ultimately, the quest for sustainability requires that as a world we be able to live off the interest of our planetary capital - that we cease to deplete non-renewable resources and that we renew the renewable ones at least the rate of depletion. We are doing neither, and thus we need all the models of closed systems we can get. When a lot of us discover peak oil or other ecological crises, we start by thinking about how we can preserve our immediate family and ourselves. There's nothing wrong with this - but we often begin from the notion that we ought to try and achieve a kind of self-sufficiency. So we often start on the journey to self-sufficiency thinking primarily about sustainability at the household or family scale. At some point, however, we look up from our family situation and realize that we can't attain security without other people around us having security. And then situation becomes larger, and seems less manageable. Sometimes we draw tight borders, imagining that we can keep those limits under control, other times we give up on the project altogether, and focus our energies somewhere else. continuescasaubonsbook.blogspot.com
