This definition of permaculture expresses a basic concept in permaculture - examining and following nature's patterns. Permaculture advocates designing human systems based on natural ecosystems. But, there are many other definitions of permaculture, just as there are many definitions of sustainable living.
The following year my favorite of the Earp movies, Wyatt Earp, featured a Kevin Costner, who, in a few scenes, looked much like the actual Wyatt Earp. Most Earp-like is the scene where Wyatt is breaking Bat and Ed Masterson in as cops in Dodge City.
Writer Stuart N. Lake did a series of interviews with Wyatt before he died and it was on that basis that a fine biography was published about him. Of course it was strictly from the Earp point of view. When Earp died, Lake became custodian of the legend. Most of the films subsequently made concerning Earp if you'll look at the credits are based on Lake's book. And of course Wyatt is a cowboy hero. It took the recent films by Kevin Costner and Kurt Russell to kind of put Earp and his accomplishments in perspective.
