Lions Roar : September 2010
SHAMBHALA SUN SepteMBer 2010 81 species, consisting of a few to thousands of species) were lost in that extinction event. The greatest mass extinction yet—two hundred and forty-five million years ago—marked the end of the paleozoic era: goodbye to 54 percent of all living families. So long trilobites, you early marine invertebrates with segmented body and exoskeleton that belonged to the same phylum (Ar- thropoda) as modern-day crabs, insects, and spiders. These and other mass extinction events happened concurrently with vast climatic and physical disturbances that were outside the norm of what species and ecosystems ordinarily survived. The extinctions were undoubtedly related to these extreme physical changes. lest I embark on a far-reaching lesson in Earth history, I’ll make the point simply: over geological time, life forms on the planet and Earth itself have continually morphed from one form to another. our seas were acidic in the Archean and our atmo- sphere was oxygen-poor in the early proterozoic. This is how I see our situation now: all beings now live on “Eaarth” during the Anthropocene epoch. like other organisms before us, we are challenged by dramatically changed environ- mental circumstances and must adjust. When I read Earth history I see it fitting with the concept of cyclic impermanence. How will the species Homo sapiens fare as we move across the epochs from Holocene to Anthropocene? Will humans and other great apes be counted among the taxonomic families that succumb in this latest great extinction? Will the record of our one-time presence on the planet comprise only an early An- thropocene stratum of bones, tools, and garbage? McKibben and Thich Nhat Hanh offer hope that, if we wake up in the Anthro- pocene on “Eaarth,” human beings may persist as one of the long- lived multicellular species on the planet (think horseshoe crab). By looking back in Earth history, I’d like to support with geological evidence McKibben’s and Thich Nhat Hanh’s sound approach to surviving on “Eaarth.” The planet’s most success- ful and abundant life forms are prokaryotes, organisms that lack a cell nucleus or any other membrane-bound organelles. Their fossils occur in Earth’s oldest rocks; they live today in nearly all environments where liquid water exists. Some thrive in harsh re- gions like the snow surface of Antarctica, while others survive at hydrothermal vents and hot springs. Some use photosynthesis and organic compounds for energy, while others metabolize in- organic compounds (hydrogen sulfide). prokaryotes keep things simple and manage with what’s around locally. Bunches living together have survived numer- ous extinction events. Their collective simplicity reveals a path for awakened Eaarthlings, one that’s light, careful, graceful, and contemplative. ♦ Gone is the geological moment when we could have avoided the mutation from Earth to Eaarth.
