Schwenk's Water, The Element of Life, remains all these many years later, still one of the very best books written about the human relationship with the aqueous world. I would go as far to say that all managers and students of water should read it for its ethical message about how to relate to the very core of life. Indeed, in my own recent work, Deep Immersion: The Experience of Water (nominated for top environmental book of the year), only Thoreau is quoted more often than Schwenk!
