Grahame and Don both have wisdom in their words - thanks guys. Permaculture for me is much more than a word. It is a banner we can gather under to combine our efforts towards (insert word here) (sustainability, resilience, community, ?) It is this banner that makes Permaculture what it is, as we all know, there is very little new in Permaculture but the value in the concept was that it was bought together into a design strategy. This bringing together, for me, is the power of the movement and so we should consider supporting the concept and using the word as a point of muster for people who are like-minded and build on the communality and value the diversity.
