When it comes to sustainable living, there is no-one doing it better than the team at Earthship.org Biotecture (click the link to view pictures of their work). And while you are on their website, take the time to explore it a little bit. They have been evolving their systems for 40 years now & they have a most excellent model that can be (& is being) exported to anywhere on the planet. I have been following them and getting their newsletter for the last 5 years. During that time I have gone from impressed to completely bowled over by their model for sustainable living, in complete harmony with your environment.

When I grow up, I wanna live in an earthship:)
