For those of you who have not seen the current issue if Edible Ohio Valley, there is part 1 of a 2 part series introducing Permaculture and its foundations, that I wrote for them. They are fairly comprehensive and should give any reader a strong foundation as to what is permaculture and why it is so critical to a peaceful future for humanity. Here is a link to the first article: http://www.ediblecommunities.com/ohiovalley/summer-2012/no9sustain.htm
Keep an eye out for the 2nd part in the fall issue of Edible Ohio Valley
