Earthhaven Ecovillage is a community of people who have grouped together to build their vision of a sustainable community. While I think that some of these people's beliefs and practices are way out there, it is the way they have structured their community that I think is interesting.
Done intelligently, I think "sustainable building" should be a guide for survivalists and preppers, after all, we are trying to become more self-sufficient and rely less on mass produced food. Designing your landscape to produce food year after year with little human interaction should be a goal for anyone not living on rented or leased property, unless you have an indefinite lease and permission from the property owner.
So what is an Ecovillage?
Sounds like a bunch of tree-hugging right?
From Earthaven's website:
"Ecovillages are human-scale, full-featured settlements in which human activities are harmlessly integrated into the natural world in a way that is supportive of healthy human development, and which can be successfully continued into the indefinite future.”
—Robert and Diane Gilman, Ecovillages and Sustainable Communities, 1991
Destroying our environment to live at odds with nature is not the brightest of ideas', not much of a future either!
Incorporating technology into a earth friendly structure would seem to be the best of both worlds. An earth sheltered or underground house would help curb temperature swings and with the integration of grey-water recycling, solar and wind power, could make for a very energy and water efficient home. Perhaps be off-grid completely.
I encourage you to take the time and visit their website and look at it in it's entirety. It should get your prepper's genes motivated.
It could be a model for a Survival community, somewhere!
