Document Summary
Societies like rome babylon etc. all seemed to live forever. A lot of culture had the imagination that they"d just disappear. Our obsession as a nation to apocalyptic shows depicts how widespread the idea is. Vulnerable: that which is susceptible of injury/ exposed to damage. Natural systems: degraded systems with critical species that are threatened, shrinking systems (islands), and systems facing unknown threats to which no defense has been created. Social systems: obvious vulnerabilities defended against eg. disease, war, disasters. In our community, everything depends on complex systems (electricity etc. ) so if anything were to happen, our entire community would face a collapse. (human systems and complex systems as a whole are very vulnerable) Resilience: the capacity of a system to bounce back from stress. Natural systems: robust simplicity, appropriate diversity, size/refugees, patchiness (complicated/cannot understand) Social systems: appropriately flexible strategies, access to resources, memory. Resilient systems find things to hold onto when they break.
