The Gaia hypothesis, proposed by James Lovelock, suggests that Earth's
living organisms and their inorganic environment work together as a single,
self-regulating system to maintain habitable conditions, such as stable
temperature and atmospheric composition. This theory views Earth as a
complex, integrated system that stabilizes itself for life, similar to a
superorganism. Initially controversial, the hypothesis laid the groundwork
for modern Earth System Science.
Key aspects of the Gaia hypothesis:
Self-regulation: The core idea is that life actively regulates the
environment. For example, the development of the oxygen-rich atmosphere
that we have today was a result of life's actions, which created an
environment more supportive of complex life than the early Earth.
Co-evolution: Organisms not only adapt to their environment but also
influence it. This creates a reciprocal, co-evolutionary relationship where
both living and non-living components develop together.
Homeostasis: The system maintains a stable state, or homeostasis, by
adjusting factors like global temperature and ocean salinity.
A holistic view: It provides a holistic framework for understanding Earth,
seeing it as more than just a planet with life on it, but as a single,
complex entity where life and geology are intertwined.

Lovelock's scientific contributions:
While developing the Gaia hypothesis, Lovelock was also an inventor. He
created the electron capture detector, which was crucial for detecting
pollutants and led to the discovery that chlorofluorocarbons (CFCs) were
depleting the ozone layer. His work on the Gaia hypothesis, combined with
his other scientific contributions, has had a significant impact on fields
like climate science and environmentalism.
Earth System Science and the ‘Gaia’ Hypothesis
Since the 1970s James Lovelock developed the Gaia hypothesis, named after
the ancient Greek goddess of the Earth (See GAIA). As originally conceived
the ‘Gaia’ concept envisages the Earth as a super-organism that operates to
regulate its own environment, principally temperature, to keep it habitable
for the biosphere. Lovelock has never argued that the biosphere consciously
anticipates environmental change, but only that it automatically responds
to it. Nonetheless some sections of the public have construed it that way,
and in the popular mind Gaia gained a quasi-mystical connotation, enhanced
by its name. The great value of the Gaia hypothesis is that it presents the
interdependence of the constituents of the geosphere in a media-friendly
way. Earth system science also involves a holistic approach to the
geosphere, but without the ‘ghost in the machine’. Nonetheless Amazon, the
internet book shop, still classifies books on Earth system science under
‘Religion and Spirituality > New Age > Earth-Based Religions > Gaia’.
Self-Organization in the Biosphere
Arguably the most ambitious ecological theory based on self-organization is
the Gaia hypothesis, which postulates that the biosphere itself evolves to
a homeostatic state. Lovelock suggested the Daisyworld model as an
illustration of how this process might occur. On the hypothetical
Daisyworld, black and white daisies compete for space. Although both kinds
of daisies grow best at the same temperature, black daisies absorb more
heat than white daisies. When the Sun shines more brightly, heating the
planet, white daisies spread, and the planet cools again. When the Sun
dims, the black daisies spread, warming the planet. In this way,
competitive interactions between daisies provide a homeostatic mechanism
for the planet as a whole. The idea behind Gaia is that ecosystems will
survive and spread more effectively if they promote the abiotic conditions
required for their own persistence. If so, ecosystems might gradually
evolve to be increasingly robust, and if this happened on a global scale,
then the biosphere itself might behave as a self-regulating system.
However, evidence for Gaian processes in real ecosystems remains tenuous
and their theoretical plausibility is disputed.
Regulation of the salinity in the oceans
Ocean salinity has been constant at about 3.4% for a very long time.
Salinity stability in oceanic environments is important as most cells
require a rather constant salinity and do not generally tolerate values
above 5%. Ocean salinity constancy was a long-standing mystery, because
river salts should have raised the ocean salinity much higher than
observed. Recently it was suggested that salinity may also be strongly
influenced by seawater circulation through hot basaltic rocks, and emerging
as hot water vents on mid-ocean ridges. However, the composition of
seawater is far from equilibrium, and it is difficult to explain this fact
without the influence of organic processes. One suggested explanation lies
in the formation of salt plains throughout Earth's history. It is
hypothesized that these are created by bacteria colonies that fix ions and
heavy metals during life processes.
Regulation of oxygen in the atmosphere the atmospheric composition
remains fairly constant providing the ideal conditions for contemporary
life. All the atmospheric gases other than noble gases present in the
atmosphere are either made by organisms or processed by them. The Gaia
theory states that the Earth's atmospheric composition is kept at a
dynamically steady state by the presence of life. The stability of the
atmosphere in Earth is not a consequence of chemical equilibrium like in
planets without life. Oxygen is the second most reactive element after
fluorine, and should combine with gases and minerals of the Earth's
atmosphere and crust. Traces of methane (at an amount of 100,000 tonnes
produced per annum) should not exist, as methane is combustible in an
oxygen atmosphere. Levels of gases in the atmosphere in 420,000 years of
ice core data from Vostok, Antarctica research station. Current period is
at the left. Dry air in the atmosphere of Earth contains roughly (by
volume) 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide,
and small amounts of other gases including methane. While air content and
atmospheric pressure varies at different layers, air suitable for the
survival of terrestrial plants and terrestrial animals is currently known
only to be found in Earth's troposphere and artificial atmospheres.
Oxygen is a crucial element for the life of organisms, who require
it at stable concentrations. Regulation of the global surface temperature
Since life started on Earth, the energy provided by the Sun has increased
by 25% to 30%; however, the surface temperature of the planet has remained
within the levels of habitability, reaching quiet regular low and high
margins. Lovelock has also hypothesised that methanogens produced elevated
levels of methane in the early atmosphere, giving a view similar to that
found in petrochemical smog, similar in some respects to the atmosphere on
Titan. This, he suggests, tended to screen out ultraviolet until the
formation of the ozone screen, maintaining a degree of homeostasis. The
Snowball Earth research, as a result of "oxygen shocks" and reduced
methane levels, that led during the Huronian, Sturtian and
Marinoan/Varanger Ice Ages the world to very nearly become a solid
"snowball" contradicts the Gaia hypothesis somewhat, although the ending of
these Cryogenian periods through bio-geo-physiological processes accords
well with Lovelock's theory. Processing of the greenhouse gas CO2 ,
explained below, plays a critical role in the maintenance of the Earth
temperature within the limits of habitability. The CLAW hypothesis,
inspired by the Gaia theory, proposes a feedback loop that operates between
ocean ecosystems and the Earth's climate. The hypothesis specifically
proposes that particular phytoplankton that produce dimethyl sulfide are
responsive to variations in climate forcing, and that these responses lead
to a negative feedback loop that acts to stabilise the temperature of the
Earth's atmosphere. Currently this Gaian homeostatic balance is being
pushed by the increase of human population and the impact of their
activities to the environment. The multiplication of greenhouse gases may
cause a turn of Gaia's negative feedbacks into homeostatic positive
feedback. According to Lovelock, this could bring an accelerated global
warming and mass human mortality.
Weak Gaia
At one end of this spectrum is the undeniable statement that the organisms
on the Earth have altered its composition. A stronger position is that the
Earth's biosphere effectively acts as if it is a self-organizing system,
which works in such a way as to keep its systems in some kind of
"meta-equilibrium" that is broadly conducive to life. The history of
evolution, ecology and climate show that the exact characteristics of this
equilibrium intermittently have undergone rapid changes, which are believed
to have caused extinctions and felled civilizations (see climate change).
Weak Gaian hypotheses suggest that Gaia is co-evolutive. Co-evolution in
this context has been thus defined: "Biota influence their abiotic
environment, and that environment in turn influences the biota by Darwinian
process." Lovelock (1995) gave evidence of this in his second book, showing
the evolution from the world of the early thermo-acido-philic and
methanogenic bacteria towards the oxygen enriched atmosphere today that
supports more complex life. The weakest form of the theory has been called
"influential Gaia". It states that biota minimally influences certain
aspects of the abiotic world, e.g. temperature and atmosphere. The weak
versions are more acceptable from an orthodox science perspective, as they
assume non-homeostasis. They state the evolution of life and its
environment may affect each other. An example is how the activity of
photosynthetic bacteria during Precambrian times have completely modified
the Earth atmosphere to turn it aerobic, and as such supporting evolution
of life (in particular eukaryotic life). However, these theories do not
claim the atmosphere modification has been done in coordination and through
homeostasis. Also such critical theories have yet to explain how conditions
on Earth have not been changed by the kinds of run-away positive feedbacks
that have affected Mars and Venus. Biologists and earth scientists usually
view the factors that stabilize the characteristics of a period as an
undirected emergent property or entelechy of the system; as each individual
species pursues its own self-interest, for example, their combined actions
tend to have counterbalancing effects on environmental change. Opponents of
this view sometimes reference examples of lives' actions that have resulted
in dramatic change rather than stable equilibrium, such as the conversion
of the Earth's atmosphere from a reducing environment to an oxygen-rich
one. However, proponents argue these atmospheric changes improved the
environment's suitability for life. Some go a step further and hypothesize
that all life forms are part of one single living planetary being called
Gaia. In this view, the atmosphere, the seas and the terrestrial crust
would be results of interventions carried out by Gaia through the
coevolving diversity of living organisms. While it is arguable that the
Earth as a unit does not match the generally accepted biological criteria
for life itself (Gaia has not yet reproduced, for instance; it still might
spread to other planets through human space colonization and terraforming),
many scientists would be comfortable characterizing the earth as a single
"system".
Strong Gaia
A version called "Optimizing Gaia" asserts that biota manipulate their
physical environment for the purpose of creating biologically favorable, or
even optimal, conditions for themselves. "The Earth's atmosphere is more
than merely anomalous; it appears to be a contrivance specifically
constituted for a set of purposes". Further, "... it is unlikely that
chance alone accounts for the fact that temperature, pH and the presence of
compounds of nutrient elements have been, for immense periods, just those
optimal for surface life. Rather, ... energy is expended by the biota to
actively maintain these optima". Another strong hypothesis is the one
called "Omega Gaia". Teilhard de Chardin claimed that the Earth is
evolving through stages of cosmogenesis, affecting the geosphere,
biogenesis of the biosphere, and noogenesis of the noosphere, culminating
in the Omega Point. Another form of the strong Gaia hypothesis is proposed
by Guy Murchie who extends the quality of a holistic lifeform to galaxies.
"After all, we are made of star dust. Life is inherent in nature." Murchie
describes geologic phenomena such as sand dunes, glaciers, fires, etc. as
living organisms, as well as the life of metals and crystals. "The question
is not whether there is life outside our planet, but whether it is possible
to have "nonlife". There are speculative versions of the Gaia hypothesis,
including versions that hold that the Earth is conscious or part of some
universe-wide evolution such as expressed in the Selfish Biocosm hypothesis
strain of a larger speculative Gaia philosophy. These extreme forms of the
Gaia hypothesis, that the entire Earth is a single unified organism that is
consciously manipulating the climate to make conditions more conducive to
life, are metaphysical or mystical views for which no evidence exists, and
that cannot be tested scientifically. The political branch of Gaia theory
is the Gaia Movement, a collection of different organisations operating in
different countries, but all sharing a concern for how humans might live
more sustainably within the "living system".
