The Land Organism and Gaia
Toward the co-evolution and advancement
of the Land Ethic and Gaia Paradigm

This brief slide show introduces a powerful
synergy between two ideas dealing with the
relationship between human beings and Earth:
1. Aldo Leopold’s “Land Ethic”
2. The “Gaia Paradigm”
![Page 3: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/3.jpg)
“In short, a land ethic changes the role of
Homo sapiens from conqueror of the land-
community to plain member and citizen of it.
It implies respect for his fellow-members,
and also respect for the community as such.”
American ecologist,
Aldo Leopold, described the
Land Ethic
in his 1949 book:
“A Sand County Almanac”
![Page 4: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/4.jpg)
Leopold wrote:
“An ethic to supplement and
guide the economic relationship
to land presupposes the existence
of some mental image of land as
a biotic mechanism.”
![Page 5: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/5.jpg)
Ecology - The study of the interactions of organisms
with their environment and with each other.
For about 100 years, our “mental image of land
as a biotic mechanism” was informed by ecology
![Page 6: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/6.jpg)
In the past few decades, our understanding
of what Leopold called the “land organism”
has advanced by orders of magnitude.
This has been due, in large part,
to James Lovelock’s Gaia Theory.
![Page 7: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/7.jpg)
“Gaia is the Earth seen as a
single physiological system,
A description of Gaia Theory by Lovelock:
![Page 8: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/8.jpg)
“Gaia is the Earth seen as a
single physiological system,
an entity that is alive at
least to the extent that,
like other living organisms, its
chemistry and temperature
are self-regulated at a state
favourable for life.”
![Page 9: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/9.jpg)
Gaia Theory provides a robust
scientific viewpoint for us to understand
the “biotic mechanism . . .”
. . . a living system in which organic
and inorganic parts and processes
have co-evolved as one.
![Page 10: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/10.jpg)
Gaia Theory provides a window
into this kind of emotional connection
through the unique story of
how and why it came to be so-named.
Leopold also wrote:
“We can be ethical
only in relation to something we
can see, feel, understand, love, or
otherwise have faith in.”
![Page 11: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/11.jpg)
Golding suggested that Lovelock’s new
scientific idea be named “Gaia” . . .
When Lovelock returned to
England, William Golding,
author of “Lord of the Flies,”
was his neighbor.
James Lovelock, developed
his ideas about Earth while
working with NASA
![Page 12: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/12.jpg)
“Gaia” is the Greek Goddess of Earth and . . .
. . . also the root
word for
“Geology”
“Geography”
“Geometry”
Golding believed that the name “Gaia” honored the
fact that modern Western science was rediscovering
what ancient Western tradition knew mythologically –
that Earth is alive and that we are a part of that life.
![Page 13: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/13.jpg)
The “Gaia Paradigm” can be thought of as the
confluence of Gaian science (now also known as
“Earth system science”) with cultural stories
and understandings (ancient and new) of how
human beings are part of a living Earth.
Most cultures have characterized
Earth as being alive, and reflected
this belief in their symbols and stories.
![Page 14: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/14.jpg)
Roman Symbol for Earth
Hopi “Mother Earth” Symbol
Zia Sun Symbol
Buddhist Mandala
Yin Yang Symbol within Korean Flag
Such cultural understandings are reflected in ubiquitous
circle and four directions symbols, for example.

Leopold’s Land Ethic was
similarly built upon his
understandings as a scientist
and as a student of human
behavior, economics, ethics
and even Greek mythology!

Most if not all of our ancestors knew
the world as an organic whole.
Science is, indeed now re-discovering the
wisdom and accuracy of these organic worldviews.

We have discovered how life on
Earth has moderated surface
temperatures over the eons that our
Sun has become hotter and hotter.

Earth’s

We understand that life
regulates the composition
of Earth’s atmosphere, thus
affecting temperature and
many other factors . . .

Leopold foreshadowed these and other
understandings that were to emerge
decades later through Gaia Theory.
![Page 23: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/23.jpg)
Consider these words . . .
“[I]t is at least not impossible to regard the earth’s
parts – soils, mountains, rivers, atmosphere, etc. –
as organs or parts of organs, of a coordinated
whole, each part with a definite function.
![Page 24: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009. Opening chapter by James Lovelock Foreword by Bill](https://reader034.vdocument.in/reader034/viewer/2022051908/5ffc0de1dab5762600219026/html5/thumbnails/24.jpg)
And, if we could see this whole, as a whole, through
a great period of time, we might perceive not only
organs with coordinated functions, but possibly
also that process of consumption and replacement
which in biology we call metabolism or growth.
![Page 25: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009.

In such a case we would have all the visible
attributes of a living thing, which we do not now
realize to be such because it is too big, and its life
processes too slow.”

Microbiologist, Lynn Margulis, understood
Earth as a living system often referring to
Gaia as “Symbiosis as seen from space” . . .
![Page 28: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009.

. . . She understood that this symbiosis
includes humanity and everything about us . . .
![Page 29: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009.

. . . including governance, politics, and ethics
and other uniquely human behavior.
![Page 30: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009.

“Politics and economics
are advanced symbioses
in which the original
free-for-all competition has
been replaced, in part,
by co-operative mechanisms
with an ethical content.”
- From A Sand County Almanac
Leopold well-understood
this “Gaian perspective”
![Page 31: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009.

“An ethic, ecologically, is a
limitation on freedom of action
in the struggle for existence.
An ethic, philosophically,
is a differentiation of social
from anti-social conduct.
These . . . are two definitions
of the same thing.”
- From A Sand County Almanac

This portends the critical
question of our day!
Will our stories, symbols and metaphors,
and the political directions that stem
from them – imbue a sense of limits?
![Page 33: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009.

Together, the Gaia Paradigm & The Land Ethic
elevate an understanding of the
importance of this question
and how to address it . . .
![Page 34: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009.

Both of these concepts are
based on an understanding that . . .
. . . our minds and behavior are a
seamless continuum of Earth’s living system.
![Page 35: The Gaia Theory - Entrepreneurial Earthentrepreneurialearth.com/.../The-Land-Organism-and-Gaia.pdfGaia in Turmoil MIT Press 2009.

“Ethics are possibly a
kind of community instinct
in the making.”
. . . our minds and behavior are a
seamless continuum of Earth’s living system.

Together, the Land Ethic and Gaia Paradigm can:
• Synergistically advance each other’s
knowledge & wisdom
• Reveal new ways of understanding and
flourishing within the imperative of limits.
