Fatal flaws and resilience...takes me back to this video posted recently on the PRI Home page - Link. Maybe all that can be done is increase the periods of resiliency and collapse is always inevitable in the larger scale i.e. hundreds to thousands of years. One example they use is a devastating fire, and nature always recovers from that. And has the ability to form better, or worse, systems after that collapse based on external factors, permaculture being that external factor in our example.
