Meanwhile, in the future Ecotopia, individuals move the local economy toward a more sustainable model. A collective sets up a solar remodeling business; a young man uses goats to mow lawns. Berkeley creates car-free zones; other cities adopt them. A suburban tract is replanted as an orchard. Rural residents build a lightweight, cheap horse-drawn buggy, and stills to distill alcohol from farm waste. Eventually, a large part of the public is car-free and ready to take the final steps to a sustainable economy.
