835.0. "Gaia" by HANZI::SIMONSZETO (Simon Szeto @HGO, Hongkong) Sat Oct 14 1989 05:16

    I could not find a topic with the word "Gaia" in it, nor such a
    keyword.  I'm not often in this conference so I don't know if this
    has been in some other discussion.  If so, a pointer would be
    appreciated.
    
    I have read not many authors in SF, but I see that some of them, for
    example Asimov and Aldiss, use this Gaia or personified ecosphere in
    their stories.  Do other authors?  IMO, Gaia, like much in SF, is F but
    not S.  Comments?

835.2Titan, Wizard, DemonARTFUL::SCOTTJesus Saves. I wish I could."Sun Oct 15 1989 11:3712
    
    John Varley wrote a series of novels (Titan, Wizard and Demon) in
    which one of the main protagonist is the neurotic central brain/god
    of an artificial ecosphere which is detect and investigated by a team
    from Earth.  This being, who has been studying the Earth for millenia,
    calls herself Gaea, and the various regions of the ecosphere, and their
    subordinate brains, are named after the Titans (in Greek mythology, the
    twelve children of Heaven and Earth).  These novels make the concept
    reasonably scientifically plausible--Gaea is a gigantic genetically
    engineered life-form.
    
    Is this the sort of thing you meant?

835.4COOKIE::MJOHNSTONA Moose Once Bit My SisterMon Oct 16 1989 17:165
	In Greek mythology Gaea (also Gaia)  was the Earth Mother, and the
mother of the Titans. I believe our `geo' and `Gaea' are both derivatives of
the Greek ge (earth).

835.5The Gaia HypothesisRICKS::REDFORDMon Oct 16 1989 19:3139
    There's a theory kicking around ecology these days called the 
    Gaia Hypothesis.  It was originally proposed by Lynn Margulis, a 
    microbiologist at Boston Univ., and James Lovelock, a English 
    scientist and inventor. (He came up with a way to detect 
    extremely small concentrations of chlorofluorcarbons, which led 
    to the orginal concern about their effects on the ozone layer).
    I believe their book on it is called the Gaia Hypothesis.
    
    The idea is that the earth is a self-regulating system, with the 
    feedback provided by biological organisms.  The earth's 
    temperature, rainfall, oxygen, and carbon dioxide levels are 
    maintained within fairly narrow limits by the action of life.  
    If the temperature rises too high, perhaps because of a change in 
    the output of the Sun, less CO2 is produced and so more heat is 
    radiated away.  If too much greenery produces too much oxygen,
    fires break out to consume it.  Other loops control other items.
    The net result is that the conditions for life are maintained by 
    life, even over the course of hundreds of millions of years.

    Some interpret this in mystical terms.  They see the whole earth 
    as alive. We are all cells of this super-organism.  It has lived
    for  billions of years and will live for billions more.  The 
    atmosphere is its skin, the earth is its bones, and humanity is 
    its nervous system.  That might be a blow to one's racial pride, 
    but isn't it better to be part of something immortal and grand 
    rather than a mayfly bag of chemicals?  That's the way the 
    eco-mystics see it anyway.
    
    Others question the whole idea, saying, a) the earth's 
    environment is not particularly stable (witness the Ice Ages), 
    and b) there are mechanical means by which certain variables can 
    be controlled.  Excess CO2 can be sucked up by combining it with calcium.
    Temp levels can be controlled by cloud cover or icecap extent.
    The scientific debate is quite vigorous, and will probably end up 
    with a combination of mechanical and biological mechanisms.  The 
    theory has inspired a lot of controversy, perhaps because of its 
    religious overtones.

    More like an "eco_torus_" actually; being shaped like an inner-tube.
