Biosphere 2 - the biggest living architecture and permaculture project of the 1990s

The NY Times recently did a retrospective on Biosphere 2. One could argue that it was the signature living architecture and permaculture project of the 1990's. It's where I first became interested in both disciplines, so as a Biosphere 2 research alum and fan I had to post the video. One of these days I'll write a long post about my time there; it was and continues to be an amazing place!
