non extraction is an interesting way to say return the surplus to the system because otherwise there will be net loss. I'm not sure in the tags line world we live in if any one word or even simple sentence is enough to convey it.
I don't mean to come off critical, I was just curious as to where this came from... I see now you're capable of your own thoughts, so many here aren't.
rock on permaculture!
