Ecology and American
Social Thought
Abstract
Despite roots that go back
to antiquity, ecology as we know it came into existence as a science
in the 1890s. It found modest institutional support, mainly in the U.S.
and Britain, during the first three decades of the twentieth century;
it expanded quietly in organization, personnel, techniques, range of
topics, and theoretical structure during the 1930s; and it came into
its own after World War II. In the postwar period its expansion was
slow at first and then increasingly more rapid, owing to the dual effects
of dramatic internal developments, some inspired by war-born research
and some simply extensions and elaborations of prewar work, and the
strong external impetus, after the mid-1960s, of the burgeoning environmental
movement. Since the subject matter of ecology is not individual organisms
but interrelationships, the science from its beginning drew heavily
upon concepts, models, and metaphors from other fields, within and outside
the sciences. It is not only a highly derivative science but also one
which by its very nature relies upon language fraught with meaning beyond
the sciences. At the same time, ecological science, regardless of the
origin of its ideas, has been called upon throughout its history to
address issues of broad social concern.
Early ecology in America reflected the
social environment of the turn of the century period, that is, a self-consciously
Christian social reform spirit coupled with belief in an evolutionarily
progressive, integrated social organism. Whether we look at varieties
of succession and climax theory among plant ecologists or studies of
animal social organization, the focus was on communities of organisms
that behaved as goal-directed, integrated units in equilibrium with
their natural environments. The underlying teleological element of much
theoretical ecology smacked of a revived form of natural theology, still
evident today in various appeals for the preservation of biodiversity.
Whatever the implicit values reflected in ecological theory, the ecologists
themselves self-consciously stressed the utilitarian value of their
science, particularly in association with its potential applications
to agriculture and forestry. Despite growing public interest in nature
preservation at the turn of the twentieth century, ecologists did not
throw in their lot heavily with the preservationists. Where they did
promote preservation of natural areas, they emphasized the scientific
value of maintaining reserves of pristine nature so that experts could
discover the laws and principles that lay hidden therein.
Social theorists began applying ecological
concepts to studies of the human community early on. In the 1920s a
group of University of Chicago sociologists adopted an ecological perspective
on urban community dynamics and spatial patterning which they chose
to call "human ecology," a research program that served its
participants as a kind of antidote to the rampant biological determinism
spawned by the eugenics movement, but which came under fire from other
sociologists for its environmental determinism and its somewhat loose
transfer of concepts and terms from the biological to the social sciences.
Just as later applications of ecological knowledge to social settings
would span the ideological space between Garrett Hardin and Murray Bookchin,
applications in the 1920s and 1930s ran across the political spectrum,
from the very conservative geographer/environmental determinist Ellsworth
Huntington, second president of the Ecological Society of America, to
the liberal social critic Lewis Mumford. In the early 1920s Huntington
made a strong but unsuccessful appeal to the Society to place human
ecology high on its agenda. Ecological knowledge, meanwhile, worked
its way more subtly into social thought during the 1930s and 1940s,
through the efforts of various geographers, environmental historians,
and regional sociologists.
Although post-World War II ecology increased
in sophistication, made use of new sampling methods and quantitative
techniques of all sorts, and drew heavily upon concepts and metaphors
borrowed from engineering and the physical sciences, many of the earlier
implicit values persisted. No matter how sophisticated the mathematical
model, population ecologists expected equilibrium conditions to prevail
under ideal circumstances, ecosystems were supposed to undergo a natural
process of development whereby they achieved something close to a steady-state
with regard to energy flow, and, within limits, disturbed systems were
expected to restore balance and harmony "naturally," a quality
that was somehow a result of the increased pathways for the flow of
energy and information, a virtue of the very diversity of such natural
systems. Although those underlying assumptions have come under attack
from within ecological science, particularly during the past three decades,
they reflected, once again, a kind of theistic view that served the
purposes of the earlier and more strident versions of environmentalism:
modern industrial society had sinned against the natural order, and
we were all paying the price.
Applications of ecological knowledge to environmental
problems found their way into postwar social and political analysis
long before Earth Day. Several works in the late 1940s and early 1950s
focused on issues relating to overpopulation, pollution, and the exploitation
of natural resources, framed within a conservative Cold War rhetoric
that would seem strange to later environmentalists. A more scholarly
and reflective assessment of environmental issues by social theorists
was provided by the 1955 International Symposium on Man's Role in Changing
the Face of the Earth at Princeton, New Jersey, where over seventy participants
discussed everything from human alterations of the ancient environment
to the recent effects of radioactivity from nuclear bomb tests, often
framing their analyses within the language and concepts of ecological
science. About the same time, cultural anthropologists, inspired by
postwar ecosystem ecology, began applying ecosystem concepts to studies
of hunter/gatherers, treating these self-sufficient human populations
as harmonious components of equilibrium systems. By the late 1960s,
when the environmental movement began to gather steam, the framework
was thus set for the elevation of the primitive hunter/gatherer to the
rank of ecologically noble savage, an idea that has been slow to die
despite compelling studies to the contrary.
With the advent of environmentalism, ecology
came to serve not only as the source of expert knowledge necessary for
curing environmental ills but also as the scientific underpinning for
a new social order. The new national environmental awareness created
all sorts of opportunities for the expansion of ecological science and
drew many more people into the field, but it also placed unreasonable
demands on a science that was, and still is, incomplete, fragmented,
pluralistic, and lacking in broad, consistent, unifying principles.
Ignoring, or unaware of, the limitations of scientific ecology, social
theorists on the political left, in the wake of the Civil Rights movement
and opposition to the Vietnam War, saw ecology as the scientific basis
for a critique of capitalism, industrialism, imperialism, modern technology,
and reductionist science. Social ecologists, bioregionalists, deep ecologists,
and ecofeminists alike shared an uncritical acceptance of ecological
ideas and concepts, treating the science not as the complex and malleable
discipline that it is but as a font of reliable knowledge, consistent
insights, and even moral lessons. Elements of the earlier Christian
reform spirit, along with a kind of neo-Puritanism, pervaded the environmental
movement. An ecological perspective, equally uncritical, found its way
gradually into mainstream economics and political theory as well. In
recent years, as the science of ecology itself has come under the scrutiny
of both internal criticism and postmodern analysis, identifying proper
applications to social issues has become more and more problematic,
to say the least. The new models that prevail in contemporary ecology,
models of directionless systems continually in flux, fit in well with
the current managerial ethos, but their moral implications, not to mention
their broader theological implications, are certainly less clear.
