Our current economy cannot possibly secure the integrity and health of the whole creation, for the simple reason that it is not comprehensive. It proceeds on the assumption that human life can be extracted from the created context in which it thrives and that economic decision-making need only concern itself with human aims. All life, as well as the natural sources that enable life, is simply reduced to human desire and whim. We can see this in the virtual disappearance of the category of land (meaning soils, water, forests, air, etc.; i.e what ecologists call the biotic community) from economic discussion–the focus is almost entirely on issues of capital and labor, exchange value and consumption. The macro-economy, as envisioned by most textbooks, is a closed or isolated system in which natural-resource inputs or pollution or the facts of entropy, never appear.
