Gaia Theory: Model and Metaphor for the 21st Century

Overview

The Gaia Paradigm

While reading on about the science of Gaia Theory – below and throughout this website – consider the term “Gaia Paradigm.” This phrase refers to the confluence of the best available scientific understanding of Earth as a living system with cultural understandings of human society as a seamless continuum of that system. The “Gaia Paradigm” employs the powerful metaphor of “Gaia” to take the perspective of human beings as part of a living system. This encourages us to explore scientific insights from scientists that have been associated with “Gaia Theory” and from those who identify themselves as researchers in “Earth system science” or other disciplines. The “Gaia Paradigm” is a context in which our society’s “cultural narrative” can best reflect and incorporate these scientific realities.

What is Gaia Theory?

Pick up a newspaper or listen to the news and you’ll quickly see that our understanding of the Earth and our relationship to it has never mattered more. The Gaia Theory offers insights into climate change, energy, health, agriculture, and other issues of great, if not urgent, importance.

Overall, the Gaia Theory is a compelling new way of understanding life on our planet. It argues that we are far more than just the “Third Rock from the Sun,” situated precariously between freezing and burning up. The theory asserts that living organisms and their inorganic surroundings have evolved together as a single living system that greatly affects the chemistry and conditions of Earth’s surface. Some scientists believe that this “Gaian system” self-regulates global temperature, atmospheric content, ocean salinity, and other factors in an “automatic” manner. Earth’s living system appears to keep conditions on our planet just right for life to persist! The Gaia Theory has already inspired ideas and practical applications for economic systems, policy, scientific inquiry, and other valuable work. The future holds more of the same.

Understanding Gaia Theory

The Gaia Theory posits that the organic and inorganic components of Planet Earth have evolved together as a single living, self-regulating system. It suggests that this living system has automatically controlled global temperature, atmospheric content, ocean salinity, and other factors, that maintains its own habitability. In a phrase, “life maintains conditions suitable for its own survival.” In this respect, the living system of Earth can be thought of analogous to the workings of any individual organism that regulates body temperature, blood salinity, etc. So, for instance, even though the luminosity of the sun – the Earth’s heat source – has increased by about 30 percent since life began almost four billion years ago, the living system has reacted as a whole to maintain temperatures at levels suitable for life.

The Gaia theory was developed in the late 1960’s by Dr. James Lovelock, a British Scientist and inventor, shortly after his work with NASA in determining that there was probably no life on Mars. His research led to profound new insights about life on Earth. The theory gained an early supporter in Lynn Margulis, a microbiologist at the University of Massachusetts. In the past 15-20 years, many of the mechanisms by which Earth self-regulates have been identified. As one example, it has been shown that cloud formation over the open ocean is almost entirely a function of the metabolism of oceanic algae that emit a large sulfur molecule (as a waste gas) that becomes the condensation nuclei for raindrops. Previously, it was thought that cloud formation over the ocean was a purely chemical/physical phenomenon. The cloud formation not only helps regulate Earth’s temperature, it is an important mechanism by which sulfur is returned to terrestrial ecosystems.

The Gaia Theory has inspired many leading figures of the past 20 years, including Vaclav Havel, John Todd (inventor), Freeman Dyson (physicist), Al Gore, Joseph Campbell (mythology expert), and Elisabet Sahtouris (microbiologist). These and many other people have written and spoken eloquently about how the Gaia Theory can help us model human activities after the living systems of our planet; the concept offers lessons for the design of economic, energy, social and governmental systems.

TECHNOGAIANISM

E-mail Print PDF

Technogaianism (a portmanteau word combining "techno-" for technology and "gaian" for Gaia philosophy) is a bright green environmentalist stance of active support for the research, development and use of emerging and future technologies to help restore Earth's environment. Technogaians argue that developing safe, clean, alternative technology should be an important goal of environmentalists.[1]


Theory

Clean techThis point of view is different from the default position of radical environmentalists and a common opinion that all technology necessarily degrades the environment, and that environmental restoration can therefore occur only with reduced reliance on technology. Technogaians argue that technology gets cleaner and more efficient with time. They would also point to such things as hydrogen fuel cells to demonstrate that developments do not have to come at the environment's expense. More directly, they argue that such things as nanotechnology and biotechnology can directly reverse environmental degradation. Molecular nanotechnology, for example, could convert garbage in landfills into useful materials and products, while biotechnology could lead to novel microbes that devour hazardous waste.[1]

While many environmentalists still contend that most technology is detrimental to the environment, technogaians point out that it has been in humanity's best interests to exploit the environment mercilessly until fairly recently. This sort of behaviour follows accurately to current understandings of evolutionary systems, in that when new factors (such as foreign species or mutant subspecies) are introduced into an ecosystem, they tend to maximise their own resource consumption until either, a) they reach an equilibrium beyond which they cannot continue unmitigated growth, or b) they become extinct. In these models, it is completely impossible for such a factor to totally destroy its host environment, though they may precipitate major ecological transformation before their ultimate eradication. Technogaians believe humanity has currently reached just such a threshold, and that the only way for human civilization to continue advancing is to accept the tenets of technogaianism and limit future exploitive exhaustion of natural resources and minimize further unsustainable development or face the widespread, ongoing mass extinction of species.[2] Furthermore, technogaians argue that only science and technology can help humanity be aware of, and possibly develop counter-measures for, risks to civilization, humans and planet Earth such as a possible impact event.[1]

Christian Theology and Gaia

E-mail Print PDF

Hildegard von Bingen receiving illuminations from heaven... The godless do not know how to act, or how to renounce. They have neither purity nor truth. They do not understand the right principles ... They say that the universe is an accident with no purpose and no God ... that life is created by sexual union, a product of lust and nothing else. Thinking thus, these degraded souls, these enemies of mankind - whose intelligence is negligible and whose deeds are monstrous - come into the world only to destroy. -- Bhagavad Gita

It is important today that theologians and others should begin to look at the Bible afresh, and to reassess its message about humanity and our relationship with the planet. A fresh reading of biblical texts about the created world order, its conservation and restoration, and some reflections on the cultural context in which these themes occur, not only in the Bible but also in other religious texts from neighbouring cultures, can tell us much about Christianity's real ecological ethic ... When the Bible's teaching on God's Creation and our place in it is duly digested, I believe that it cries out to us: 'you are fellow-creatures of everything else in the Cosmos. You have no right to exploit or destroy, but you have duties to all, under God to whom you are responsible.' -- Father Robert Murray

Many people today are calling for modern religion, and specifically Christianity, to be re-imbedded in the cosmos, so that religion might become a real force in providing the ethical and spiritual energy for the critical task of reversing the degradation of the Earth. -- Vincent Rossi
