Movement have phases and timing.
I think the main movement going on here is akin to the movement from agricultural to industrial society. As to timing, I think we are still at the early stages of this movement and still trying to envision how it will be different from what we know. Unfortunately, most of us are still thinking in very separated ways about our connections and having a difficult time make linkages. Naming is powerful. If we can agree to a definition of sustainability that is more about sustaining LIFE, then the word becomes a bit more useful to us as a tool.
