There’s little natural about the boundaries that divide states and countries. They’re often imaginary lines that result from history, conflict, or negotiation. But imagine what the world would look like if borders were set according to ecological and cultural boundaries.
Bioregionalism says that’s the only logical way to divide up territory: Let watersheds, mountain ranges, microclimates, and the local knowledge and economies that exist in them guide the way we set boundaries. That way, life within those boundaries is tied together not by arbitrary decisions but by common interests. For instance, in the United States, there are many cases where ecologically and economically distinct areas are encompassed in one state, which makes for political difficulty.
Oftentimes, no matter who wins in elections or policy, someone is left out or disenfranchised. Governing ourselves in smaller, naturally-bounded regions might ease those tensions.
