Downsizing Cities To Reduce Global Warming Threat

"In his new book, 'The End of the Street: Sustainable Growth Within Natural Limits,' architect David Dobereiner outlines a vision for replacing blighted inner cities with high-density developments that cluster community facilities, commercial areas and housing around large public plazas."

"Taking a cue from bees, ants and other creatures that create efficient communities, Dobereiner proposes to replace the square grids that make up most cities with roundish clusters shaped like amphitheaters."

Some in the architecture community have praised his forward thinking for years, calling him a "visionary". But many others see his ideas as impractical.
