Earthships really are the way forward. Seems so odd to me more people don't live in them!
As for the map you would have to ask @eco-alex. The map I created for the film showed only the communities I know of, in Bali, Mexico & a few around Europe.

We are collecting a ton of fruit at this time of year which is being preserved in various ways for the winter. Lots of veg too is going in the dehydrator. Makes great chips!
