It is axiomatic in biology and ecology. (And physics and chemistry) that resources are available at the interface between two systems.
Within each system, resources are tied up in cycles, situations, and conditions that prevent movement of those resources. The resources are relatively unavailable. The mechanisms that support and stabilize the system have developed such that when a resource becomes available it is immediately captured and put back into the system.
Resources on the surface of a system, at the edge, the border, are more available.
The more chaotic the border, the more readily available are resources.
We stir sugar in a glass of tea, in order to increase the chaos on the surface of the sugar crystals and dissolve the sugar.
Resources tied up in stable cycles are moribund.
Introducing chaos, shakes those resources loose, making them available to other outside users or more powerful users.
The last 70 years, the so-called pax Americana has allowed stable resource cycles to develop within and between countries around the globe.
A little chaos will destabilize those cycles making resources available to other users.
The US is the most powerful user in the world.
Get ready for the age of abundance.
