James Conaway is the author of "Napa: The Story of an American Eden", "The Far Side of Eden: New Money, Old Land, and the Battle for Napa Valley", and "Napa at Last Light: America's Eden in an Age of Calamity," a trilogy of books about wine and wineries in California's Napa Valley. James argues that serious changes are needed if the Napa Valley is to survive as an agricultural eden in the future. He points out threats to the Valley from climate change, limited resources, increased vineyard and winery development, and an emphasis on welcoming more and more tourists to the area. He explains that for him wine has a moral component which is often ignored, and argues that a wine choice is also a political choice.
