In Cities is the Preservation of the World.
Price criticizes "the popular American delusion, which nature writers have encouraged, that nature is where cities are not." Millions of Americans have followed Thoreau into the Waldens of the world, and the result has more often been sprawl and pollution than the preservation of anything.
This blog attempts for Portland what Price advocates for all of our cities: to bring nature writing out of the quasi-mystical frontiers where people aren't and into the cities and suburbs where we actually live.
If we accomplish that, we'll literally bring environmentalism closer to millions of people.
