If we ever start living sustainably, as we should, it's actually going to get even more complicated to decide how to go about it, not less. Where do we encroach? How do we encroach? What is natural? What is traditional? What is most desirable? What are all the principles that apply? How do we decide which principles over-ride others in any given situation? Who wins? Who loses?

We all more or less agree to separate Church and State and Nature?
The real question is how?
