You're close. And what does one do with them when you get them there? How do you keep them focused upon doing something productive, learning a skill or taking responsibility for one's world?
It's doing the hard work of weed control and habitat restoration, with the opportunity to see native plant systems respond over a period of years. Whether it's hands on, fire management, application of herbicides, tilling, animal management, or predator control, it is the satisfactions and frustrations of the feedback that matter. It is the relationships that develop that matter. The most therapeutic thing of it is the quiet.
For me priority one is get the homeless far away from civilization so we can get our cities back.
Anything after that is just a footnote.
