Layne Wyse recently posted a link about a book by photographer Alex MacLean titled Over: The American Landscape at a Tipping Point. It’s filled with aerial shots showing human patterns of development and their impact on the environment. I didn’t realized there was a fair amount of waterfront property near Phoenix Arizona before seeing this book. You should definitely check out his pictures, either on NPR or by visiting Alex’s website and clicking the “New Book: Over” link. You can also buy the book (and see even more photos) on Amazon.
