I am so living in a cob house with an extensive green roof, and no one can stop me. The icelanders have the right idea.
I am psyched. Now of course I need land. Land with lots of dirt on it.
This is not just for hippie reasons, it just seems like it would be so much cozier and right to live in the dirt. Like a hobbit. I think the neo-hippies will have to live in some kind of earth shelter, or perhaps an earthship. I can even see a transhumanist overlap there.
