I find it ironically amusing that Dr. Seuss's classic parable of the incompatibility of global capitalism with Gaia has become so iconic and subversive that corporations and republicans would seek to ban it altogether from children's libraries.

The Lorax's parting advice to the boy protagonist is still well worth contemplating: "Unless someone like you cares a whole awful lot, nothing is going to get better--it's not." The "very last truffula seed" may well be an evolutionary dead end, as you say (like the last black rhinoceros that they are now trying to clone), but ecological regeneration happens--though on a geological time scale that is meaningless to us mere humans. Still, we each can "care a whole awful lot" by growing gardens, growing community, and growing awareness, and by learning, teaching, healing, and creating Gaia...
