During the last
one-millionth part of Earth’s history, the biosphere has undergone a dramatic
change. Since the evolution of agriculture 10,000 years ago, eco-systems have progressively
made way for farmland, and lately, for industrial wasteland and concrete
jungles. Within the last fifty years this process has escalated so dramatically
that the amounts of carbon-dioxide in the atmosphere, at a steady decline over
most of our planet’s venerable lifespan, have suddenly begun to rise.
Simultaneously our planet has become an intense emitter of radio-waves. Like a
star about to supernova sending out a final blast of gamma rays into the void,
planet Earth’s apotheosis seems to be fast approaching.
The pulsing
‘skin’ of human technology (including agriculture) that has covered much of the
planet can now be seen from space. By day, the smoke from slash-and-burn
agriculture obliterates most of the tropics and by night the heady guzzling of
fossil fuels lights up the darkness. Yet underneath it all lies an ancient network
of organic weather systems, oceans, rivers, and biomes, a living and evolving planet
that can’t be totally divorced from the artifice of humans. During the 1970’s,
shortly after the first picture of our blue-planet was televised, Lynn Margulis
and James Lovelock extended the concept of the biosphere and came up with the
science-fictional notion of Gaia. Described as a self-evolving and
self-regulating living cybernetic system, Gaia is described as a giant feedback
loop existing at a far-from-equilibrium state, a meta-life-form or self-organising system that comprises all terrestrial
life-forms, including the atmosphere, and extending even down into the tectonic
plates. For techno-theorist Donna
Haraway, such a living system is already, and has always been a machinic and
technical assemblage, “terminally blurring the boundaries among the geological,
the organic, and the technical … in itself a cyborg … the natural habitat, and
the launching pad, of other cyborgs”.In
other words, our machines represent an extension of nature into abstract and
conceptual realms as much as nature is already machinic. After all, as Manual
de Landa points out, humans can only imitate what nature has built already.
Even our fastest supercomputer can’t begin to match the processing power of an
insect’s brain.
The real
question we need to ask ourselves, writes anthropologist Jeremy Narby, is
whether the same nature that evolved the brain that’s writing these lines is
really as dead, dumb and random as reductionistic science would have us
believe? The notion that the planet itself is ‘minded’ is a venerable one. Alchemists and the archaic shamans imagined that
our planet was a living network or sentient weave and they populated it with an
array of vegetable, mineral, bestial, and celestial intelligences. These hybridized
spirits wove their ‘code’ into the eerily interconnected matrix of life,
controlling the weather, the movements of animals, and the welfare of human
communities. For shamans caught up in
ecstatic trance, this matrix served as a self-revealing communications network
through which flowed pathways, chunks of data and minutiae – information on
every thing that was alive, dead, or yet to be. When Lovelock and Margulis’s Gaia hypothesis first came
to light in 1969, it merely revitalized this archaic conception of a conscious
latticework of planetary information spaces.
Likewise, the tinkering of the US Military Industrial complex with
various Artificial Intelligence (AI) projects as well as the Internet also
represented and still signify serious efforts on the part of techno-science to
engender a mechanized self-regulating planet-wide communications system and
network of intelligence with a mind of its own.
Whilst
various writers of sf such as Dan Simmons (in Illium [2003]) and William Gibson (in Count Zero
[1986]) have imagined future scenarios in which the mechanosphere of today, fed by various AI programs, attains sentience and
becomes a living, self-regulating assemblage, Gaia - the “vegetable matrix” of planetary intelligence - is described by
Lovelock and Margulis as having achieved this status approximately 3.5 billion
years ago. “One billion years after its
formation, our planet was occupied by a meta-life form which began an ongoing
process of transforming this planet into its own substance”, claims Lovelock,
toying with the idea that humans are but the latest expression of an ancient
planetary mind that has thrown up countless other life forms across its
venerable lifespan.
Given humankind’s increasing danger to the
planet (through pollution and overpopulation), we are arguably at an ecological
and ontological crisis point.[i] Humans and their artificially constructed
mechanosphere could represent the onset of a bio-technological apotheosis
whereby nature either withers and dies, or skips the organic and goes into
silicon - perhaps via us. Alternatively,
as Lovelock warns in his latest book, Revenge
of Gaia, nature may be gearing up to get rid of us altogether – or rather,
we are gearing up to get rid of ourselves. “After all,” jokes Lynn Margulis,
“Mother Nature is a tough old bitch.”
There’s no doubt that spaceship Earth will
survive the depravations of global warming, overpopulation and goddess-knows
what else, but there’s also very little doubt that no mischievous bipedal
monkeys will be around (in their present form, anyway) causing havoc during Her
final 5 billion year journey.
[i] Fossil records indicate that the earth
has thus far undergone five major planetary extinctions, of which the
disappearance of the dinosaurs is the best documented. Recent estimates hold that we are fast
headed for another massive extermination of terrestrial lifeforms. Conservative approximations hold that at
least 27,000 species of animals and plants are vanishing from the earth’s
tropical rainforests alone each year and that the earth will practically be a
barren wasteland by 2050. Biologists
speculate that 80% of all life-forms will be wiped out this time … but that’s
still better than the 95% that went extinct at the end of the Permian 251
million years ago. Despite such devastating blows, Gaia has proved more than
capable of jumping back – each time with more renewed vigour than before. Two
extinctions later (at the end of the Cretaceous – 65 million years ago), Gaia
seems to have hit an all-time high. Earth has never known such an abundant
diversity at any time during the last 3 billion years as the one that the human
species is about to terminate. Perhaps Gaia is hedging her bets on the small
chance that if things get really miserable a small number of her human children
may have gotten crafty (and posthuman) enough to leave the biosphere and follow
their radio waves into the outer darkness. To boldly go and seed other Gaias
throughout the universe (and perhaps throughout others also), we will have been
Gaia’s sperm or egg.
