It's not easy to watch the suffering of people and knowing how much of it is true for ourselves. I always watch these kind of documentaries and feel that a few blazes of Permaculture could add so much to the place. Even if that place has its' own major issues. Even if in some years the police may raid it and force everybody off of the property.
Maybe a week of inputting some resources, some land design, and some structuring to help those who would appreciate it the most. Even just doing some water-capturing work.
I don't know if I'm just naive and idealistic, but I feel that those most hurt, people and places, enjoy Permaculture the most.
