In Arizona scientists tried to create the perfect isolated,
self-contained, self-sufficient community called "The Biosphere". The
Biosphere was not created all of the same reasons that a pedestrian
community might be created, but an interesting project. Unfortunately,
rumor has it, that the Biosphere was contaminated by the delivery of
Dominoes Pizza - true or not, I think that it would be difficult for
society to take a step "backwards" and live without the "luxuries" that we
have become dependent upon.
