Book excerpt: A Million Tiny Things chronicles the escapades of a wannabe "green mom" trying to keep her sense of humor while hanging on to a lifeline, or at least a laundry line, of hope. In this age of anxious parenting and frantic Save the Earth messages, Kenna Lee answers the question, "How do we stay out of denial without getting depressed?" With a willful optimism, Lee travels the long distance from eco-overwhelm to self-forgiveness via a growing belief that large numbers of small pro-environment actions can add up to a better world.
