Permaculture systems seek to stop the flow of nutrient and energy off the site and instead turn them into cycles, so that, for instance, kitchen wastes are recycles to compost; animal manures are directed to biogas production or to the soil; household greywater flows to the garden; green manures are turned into the earth; leaves are raked up around trees as mulch.
The conscious design and maintenance of agriculturally productive systems which have the diversity, stability, and resilience of natural ecosystems. It is the harmonious integration of the landscape with people providing their food, energy, shelter and other material and non-material needs in a sustainable way.
The [Lake Erie] ecosystem underwent a series of changes, each of which were related. There was an increase in the human population; which led to higher phosophorus levels in the water; which led, at last, to an increased level of algae in the lake. In effect, Lake Erie’s ecosystem was rewritten. Changed by human activities into…something else.
But Franklin cites the study because it’s doing something slightly novel: applying Selye’s principle of stress to ecological systems, suggesting that they are, much like humans, just as susceptible to external stressors. And I’ve been thinking about that a lot lately, especially this week. Because Franklin’s suggesting that the work begins not by “fixing the system.” Rather, she suggests it’s about shifting the priority a little: to removing whatever stress you can.
I remain mystified by what seems like an exponential increase in the need to communicate induced by the availability of a ready new means to do so, just as new highway capacity produces increased traffic. Witness the cabdrivers who talk uninterrupted on the phone as they travel the city, or the truly huge numbers of people who speak on the phone as they walk down the street: the medium has clearly become the message, if the meaning of the message remains somewhat opaque.
