I will, but I think I read quite some books about it and visited many permaculture farms and tried to apply technics in my own garden quite some time ago. And my conclusion is, there is way too much wishful thinking involved. For example I have never seen a permaculture farm that was actually self sufficient. Either they had other sources of income, or they had paid tours.

Permaculture is nice and I would like to see more of it adopted, but I don't see at all, how we could feed the current world population with it. With general ecologocal farming, yes.
