I'm a journalist who's written a lot about sprawl and smart growth. Here's a story just published on sprawl for a big California newspaper, The Sacramento Bee.
It looks at the role of sprawl in the housing/economic/banking collapse, in particular. Please let me know what you think, and if you have suggestions for me for a followup.
Also, I'm particularly interested in whether the foreclosures and abandonment in the suburbs, and the 'shinking cities' phenomenon have led to changed land use, more agriculture, and possibly to more native landscaping, thus improving the future of flora and fauna.
