The greatest opportunity for change exists at the limit, where boundaries and borders exist. In the global arena, boundaries and borders exist to delineate and reinforce power structures, the antiquated model of empire and identity. Yet, if we shift the narrative and study nature, we see that what we normally utilize as spaces to differentiate and separate, exist as spaces for shared growth and opportunity. In fact, rivers always have been shared spaces for dialogue and community.
In the same way, the borders and boundaries of our "properties" offer unique opportunities to grow food together, thereby engaging in a cultural shift that redefines how we community together.
There are many ripe examples of how this works; simply imagine a living hedgerow that offers varied food and organic matter that replaces a sterile plastic white fence. In my own neighborhood, I personally witnessed a neighbor put up a fence along side another fence to avoid having an actual dialogue with their neighbor. If they had asked me to negotiate the border dispute, I would have simply removed the fence all together, and planted for them a diverse and ecologically minded boundary full of opportunity for fodder and community. A thoughtful design would have allowed their pets to mingle rather than snarl, and for them all to enjoy a bounty of goodies for the pantry.
