fantastic post! one of koehler's best. right from the top this clause, "when natural forces and human forces became intertwined," caught my mind's eye, too. perhaps blame it on my few precious drops of tsa-la-gi blood but i know that human forces exist as a subset of Nature's forces. most western religions teach that only humans are "created in the image of god" and therefore, separate from and above all else in Nature.
this anthropocene era may be the shortest of all previous geological eras. what we, collectively, have set in motion could well prove suicidal lest some greater physical force halt the current
projectory er, i mean trajectory. after all, a body in motion will continue to move unless another force can intervene. i think robert koehler may have named that force when he suggests "a spiritual shift."
I hear the largest challenge that humanity has ever faced or imagined — a challenge that transcends religion, politics and science, indeed, everything we believe and everything we know, or think we know. This includes a belief in our own reckless immaturity.
hopefully, as more and more of us recognize the seriousness of our current state our species may decide to face the music and grow up. we need to imbrace a new way of thinking about ourselves as a species and our Earth--our only home in the universe. just as the first settlers learned to live in harmony with Nature, we can learn how to "be fruitful and multiply" the precious gifts from Mother Nature leaving our children something better than a scorched and depleted land and an unpayable debt. we are not yet partners with Nature. we are, as a species, self-centered little brats with great tech toys and never a thought as to how our actions reverberate. unless we outgrow our anthropocentric tunnel vision the anthropocene era may be the last this species records.
