I recently read The World Without Us by Alan Weisman (2007).
This book was an intriguing examination of what might become of planet Earth if we humans disappeared from the planet.
In articulating the possibilities, AW takes us on a journey of prehistoric likelihoods to cosmic eventualities, of pristine ecologies past to plasticized eventualities, of organic beginnings to radioactive legacies, of worldly wonders to decompositional fate, of human depredations committed to the restorative ironies of mutual destruction.
Though I've been marching steadily toward a more deliberate "greenness," this book has caused me to think even more deeply about appropriate, respectful stewardship of this magical planet and the resources with which we've been blessed.
However the days/years/millennia ahead unfold, destiny will most assuredly hold to this unrelenting trend: Mother Nature inevitably bats last.
Thanks, MH, for the recommendation. Well worth the time.
