It
is now widely recognised around the world that we are living on a threatened
planet. Or, more specifically, threatened life on our planet.
We have endangered species of mammals, birds, fish and other animal
and plant life; we have air pollution, water pollution and soil degradation;
we have a gaping ozone hole radiating ultraviolet light upon all living
creatures whose evolution has not provided sufficient means of physiological
protection from it; we experience extremes in climate bringing floods
and droughts on an unprecedented scale; and, in the human urban societies
of the world, violence and corruption have become part of the 'norm'
of daily life to an extent which has become an entirely new phenomenon
in human history.
Our
response is anxiety. We somehow expect governments, scientists, people
who do know the nature, extent, and gravity of these problems to exercise
their authority to set in motion appropriate resolutions. To do
something.
I
want to put before you the idea that human intelligence, integrity,
and creativity are commonly found amongst all people on earth, and that
this reality is our only real resource for reversing the disorders
besetting and threatening our globe. The problems are so complex, so
interwoven, and so all-enveloping in their outcomes, that no single
body of scientists, of well-meaning politicians, or of any other group
with specialist expertise, can hope to confront them successfully. But
that does not mean that the problems are not manageable and, indeed,
reversible.
We
are all motivated to act whenever and wherever we see threat to life.
But for effective actions we have to grasp what the threat means, and
why it exists. Already a good many people have a fair grasp of what
our environmental threats are. And they are working at them. But what
looms largest of all is that the destructive forces currently at work
on our planet are gathering pace much faster than we are progressing
towards reversing the disintegration of the life-supporting capacity
of the globe.
It
is my conviction that people with some measure, or grasp, of the threats
to life must now engage in dialogue on a sweeping scale. Informed dialogue
accelerates better understanding leading to more effective actions.
It is our ways of communicating which must be re-examined urgently.
And changed.
The
"Catalyst 95" title of the Design and Environment conference
held at the University of Canberra expressed well the challenge we face
in exploring communication connections. The "Design" professions
and those of the "Life Sciences" who met at this conference
are concerned with human interactions with the environment: our habitat.
Think
for a moment of Designers whose concern is with what we call the "built
environment"; that is, the cities and towns, buildings, their fittings
and furnishings, and all the other structures providing for human activities.
We need them for manufacturing of industrial products, for the service
industries making those products accessible to their users, and for
the transport of people and goods.
And
now think of the Ecologists whose concern is the 'natural environment':
that great diversity of life forms and their physical and chemical environments
which collectively make up the biosphere.
It
is generally recognised today that these two very different kinds of
environmentsthe built and naturalinteract. What happens
in one will change what happens in the other. Over the last few decades
such changes have been manifesting themselves at a bewildering pace.
We can all recall published work identifying some particulars among
these changes. Let me instance three: two Australian and one international.
Stephen
Boyden, an ecologist, has shown that some aspects of western culture
are dangerously out of control now, leading to dire consequences which
may put the very survival of the human species at risk.
Tony
McMichael, a medical researcher, has applied both a biological and ecological
approach to his research on epidemiology and illness. He finds direct
connections between human health and well-being and the total environment
in which we live. "...the risk arises from the disruption of natural
systems because we are exceeding the biosphere's carrying capacitythat
is, we are overloading the planet's 'metabolic' capacity to absorb,
replenish and restore."
Finally,
the recent statement issued as a warning to humanity which was compiled
and signed by no less than 1,575 scientists from 69 countries including
99 Nobel Laureates, together with senior office-holders in prestigious
scientific academies in Africa, Asia, Europe, North and South America.
This statement reveals that we have only a few decadesa period
well within the single lifespan of the majority of people on earth todaybefore
the destructive impact of humanity on the global environment reaches
a point where the planet will be irretrievably damaged, bringing with
it human suffering on an unprecedented scale.
Conservation
and restoration programmes have begun. Among their active participants
a claim for political power has already surfaced. If we are to feel
encouraged by this, we have also to recognise that any changes for the
better which have been won are coming at a pace too slow to overtake
the existing rate of change from destructive forces at work today.
The
first world-wide alert signals came from the international symposium
in Stockholm in 1972. We learned there were massive life-threatening
forces at work and the need to address them was urgent.
Not
much had happened in terms of global repair by 1992, twenty years later,
when The Earth Summit was held in Rio de Janeiro. That Summit took place
in a spirit of high hope for inaugurating change in human habits to
bring about recovery from our weakened environmental life-support system.
At Rio, 150 countries signed two U.N. Conventions on Climate Change
and Biodiversity.
We
have now travelled 23 years in time since the first world-wide alert.
With what result? Our efforts at global repair are making slow headway
but remain puny.
It
is now clear that modern human societies have long been pursuing their
own perceived wants and needs, each in isolation one from the other,
with scant thought to our total dependence on the environment. Our inability
to recognise the intimate and constant interaction between societies
and the environment is affecting both the biological processes of our
'natural environment' and the physical and psychological health of human
societies everywhere.
The
title of this paper is "Maladaption or Creativity?". Notice
the word 'or'. Maladaptations are specific physical and cultural activities
we engage in which affect the immediate environment and are functionally
incompatible with the larger environment which is the global life support
system. We ourselves are an integral part of this system. As intelligent
creatures we can now recognise this fact.
What
it means is that we must satisfy our social and biological needs in
a manner compatible with the essential needs of the biosphere. We cannot
be creative by achieving one at the expense of the other.
Creativity
is only achieved when the social strategies we develop, along with the
structures and artefacts we design and make, are functionally sustainable
within the ecological limits imposed by the global life support
system.
This
is the imperative need. And its urgency is such that designers and ecologists
must pool their knowledge in order to redress damage done by our maladaptive
human practices. Between us we must find a new free-flowing way of communication.
The challenge is not to invent new technologies. It is learning to use
the technologies we already have in ways which will slash their destructive
capacity and go on to find ways to make them more sustainable within
the Earth's biosphere.
The
communications bridge can be crossed only by sharing specialist-area
knowledge. And this vital bridge? How do we build it? By whole-heartedly
setting in place co-operative relationships between one specialist group
and another. Each will discover the elation of new-found understandings
leading to new value systems in their work. It is only the first bridge.
Others will need to be erected, whereby whole communities will be able
to reassess their value systems, their lifestyles, and their world views.
In
pursuit of that first bridge, as an ecologist, I want to consider well
established research findings which have identified five major areas
of concern, each one now at a critical stage.
These
are:
1.
Changed atmospheric conditions: global warming consequent upon the
enhanced greenhouse effect; altered distribution of light and other
forms of radiation especially ultra-violet; the degradation
of air quality both indoors and outdoors.
2.
Reduction in water quality and quantity.
3.
Rapid extinction of animal and plant species consequent upon habitat
destruction and a variety of human impacts.
4.
Excessive and inappropriate use of space.
5.
The need for clear-cut information that will enable people everywhere
to readily understand those environmental issues relevant to their
capacity to take appropriate productive action.
None
of these issues is too big for individuals to make a real contribution
to their control, and eventually reversal. They have come about through
maladaptive practices of individuals. For the most part they can only
be remedied by the cumulative creative actions of individuals. Let me
turn now to some considerations of each of these issues.
1.
Changed atmospheric conditions
Global
atmospheric conditions are of vital consequence to all living organisms,
including ourselves. We cannot consider them as separate from those
prevailing where most of us live out our daily lives: the built environment.
Atmospheric
conditions embrace temperature, light, other forms of radiation, available
moisture, and the composition of the air we breathe. All occur across
a certain range of quantities, intensities and frequencies. To these
conditions plants and animals have evolved adaptive faculties which
enable them to survive and reproducewithin the particular range
of conditions which prevailed throughout their evolution. There is no
clear cut-off point at either end of any evolutionary determined range.
The degree to which we either exceed or deprive ourselves and other
living organisms of that pre-determined range will largely determine
the intensity and kind of destructive stress placed on all life forms.
All
plants and animals have a compatible range of conditions which must
be available to them wherever they are living. When conditions exceed
the extremes of that range stress occurs. If that stress is sustained
over time the cumulative effect will destroy the organisms involved.
The
effects of global warming on atmospheric conditions are complex. It
is projected that emissions of carbon dioxide continuing at present
levels will increase the Earth's average surface temperature by 1.5ƒ
C to 4.5ƒ C in the next 100 years. If that increase averages 3ƒ C, such
a rate of change would be greater than at any time during the last 10,000
years. And there would be a rate of sea level rise of some 6 cm per
decade, mainly owing to rising sea water temperature and the resulting
thermal expansion of the oceans.
The
full impact of such changes may yet be avoidable. The biosensitive approach
of "The Halifax Eco City Project" in Adelaide sets a good
example. This proposal is to build on land in Adelaides inner
city areas an integrated residential and small business development
designed according to ecological principles. That is, as an "energy
conscious city" characterised by large suburban areas that integrate
forests, woodlands and grasslands with extensive use of renewable energy,
such as solar and wind, energy efficient buildings, and less dependency
on car usage.
The
quality of the air we breathe in all cities has deteriorated alarmingly.
We all know that. But we do not all know that the air in our work places,
homes, schools, and cars has also deteriorated alarmingly. Yet this
is where most of us average about 90% of our time. If those places we
occupy in the built environment are not well ventilated, the air is
further degraded by emissions of pollutant chemicals from synthetic
furnishing materials, surface finishes and cleaning products. Here is
a major creative focus for designers. And from the Interior Designers
Handbook of 1991 we discover research has shown that indoor plants can
significantly maintain indoor air quality by absorbing a number of the
health-threatening vaporised chemicals.
We
are still coming to terms with the depletion of the ozone layer in the
earth's upper atmosphere, but we know that more ultraviolet radiation
is reaching the land and waters of the biosphere as a result. The filtering
function of the ozone layer has been a constant in the earth's atmospheric
conditions for millions of years. Yet in just a few decades human activity
has brought about the degradation of that vital function of the ozone
layer. The resultant increased levels of ultraviolet radiation not only
lead to skin cancers. They can also affect adversely many of the materials
within buildings which we regard as necessary to make them pleasant
places in which to live and work. Ultraviolet radiation can leach the
colour of painted and other surface finishes, it can degrade valuable
paintings and prints, and cause fabrics to disintegrate. Together, these
effects destroy valued aspects of the human built environment.
Even
in passive solar houses it will now be necessary for designers to find
the means for filtering out ultraviolet radiation without loss of visible
light. Recent research has shown that light levels are dangerously low
in most building interiors. We now know that the appropriate range of
visible light intensities, without glare from the source, has a positive
impact on our ability to perform tasks, on our emotions and moods, on
our immune system and general health and well-being.
Many
of us can recognise these effects of light upon ourselves. For the most
part, while we don't welcome them we put up with themfrom habit.
But the need for adequate natural light in buildings to promote effective
productivity and our sense of well-being is understood by designers.
Occupants fear the cost of providing it. But the cost of inadequate
light sources is far greater upon society as a whole. Most suburban
houses in Australia have interiors which are poorly lit, are poor aesthetically,
and have limited or no outlook. These are factors which can lead to
a general state of depression in people which in turn can cause various
forms of morbidity. If not relieved they can contribute to behavioural
disorders and a range of social problems.
Well-documented
research has shown the importance to human health and well-being of
views from windows to landscapes with trees, hills, birds and other
animals. We, ourselves, underwent our own evolutionary processes in
a world of living landscapes. It is worthy of much closer investigation
to enquire whether the stress we all feel from that deprivation in our
built environments may not be an important root of the widespread social
disorders in the world today. It is certainly manifest in the world-wide
interest in wildlife, rain forests, and the natural 'wonders' which
have given rise to the burgeoning industries of tourism and high-rating
TV programmes.
Changed
atmospheric conditions are not just a threat to animal species,
they may already have helped cause the decline observed in amphibians
world wide. A very recent scientific report is suggesting that this
decline in frogs, toads, and the like, is not only due to habitat destruction
and water and air pollution, but also to ultraviolet radiation exposure
affecting amphibians which lay their eggs in the open. Increased mortality
in their eggs and larval stages is now a reality.
This
should come as no surprise, The longer an initial problem remains, the
more secondary problems it will generate. There is now widespread agreement
among those with specialist knowledge that our society has reached a
stage where governments and individuals are spending more time, energy,
and money, on trying to overcome the destructive side-effects present
in our environment than they are on thinking through sensible, constructive,
life-sustaining activities.
2.
Water quality and quantity
Clean
water is essential to life on Earth. We all know that. And most of us
know we waste it and somehow or other contribute to its pollution. The
present "politically correct" line of thinking that sets up
"awareness raising" in the community at large is particularly
pathetic rhetoric. A recent United Nations forum even went so far as
to suggest that public awareness of the need for water control could
be emphasised by changing the name of our planet from "Earth"
to "Water" since 75% is comprised of oceans, and most of the
fresh water forms the ice-caps of the polar regions.
The
fact is that only l2% of the Earth's fresh water is available
to human populations. And everywhere urban populations are polluting
it through sewerage effluent, the dumping of toxic chemicals, and the
free use of household detergents. But we are generally not aware of
this. Few residents, for instance, in CanberraAustralia's national
capitalrealise that they are residing in, and thereby influencing
the water quality of, a major catchment area, the Murray Darling Basin,
which produces some 50% of the total agricultural production of Australia.
In
Australian urban areas most residents maintain one or other of gardens,
grassed areas, window boxes, terrace plantings and indoor plants. Careful
use of water in maintaining them is essential to the plants' lives and
to our human well-being, But a great deal of waste and damage is caused
by an inappropriate selection of plants, by using spaces unsuited to
growing conditions, by poorly designed plant containers and by not providing
low-maintenance watering and drainage systems. The designer, however,
can readily create both planting plans and watering systems as an integral
part of house design. Wherever the integration of the built and natural
environments does occur, householders quickly learn to place a high
value on water and air quality both as it affects themselves and the
wider community. However patchily this integration has occurred so far
it is an important example of successful linking of the professions
of ecology and design.
3.
Rapid extinction of animal and plant species
Ecologists
see habitat destruction and disappearing species as one of the great
conservation issues of our time. The rapid growth and spread of the
human population is now threatening the diversity of living organisms
and the ecological integrity of the Earths biosphere. The total
human impact can be seen as the product of population numbers and of
the impact per person. Both have been increasing dramatically over the
last two hundred years and continue to increase exponentially. Human
population stands at some 6 billion today and it is increasing by some
80 million people per year.
One
eminent ecologist has thought of our existing and foreseen environmental
problems in terms of "The end of biological history?". The
sheer size of human socio-economic activities now rivals the natural
processes that built the biosphere and maintain it in a habitable state.
An astonishing 40% of the earth's most basic resourcethe
incoming solar energy stored by plantsis now taken over by the
human species. As we assume control of this "net primary production"
through agriculture, pastoralism, forestry, land clearing and urbanisation,
there is less available to sustain other species.
When
we contemplate 'life on earth' we tend to think of ourselves, and the
birds, fish and other plants and animals we commonly see or know about.
Yet the vast majority of living organisms are small and inconspicuous
micro-organismsinsects and other invertebrates, bacteria and fungiwhich
are fundamental to the fertility of soils and the recycling of nutrients
through ecosystems. What they do are the "public service functions
of nature". In addition, from a medical point of view, 40% of
all prescriptions contain drugs of natural origins, and humankind has
as yet only looked at a fraction of biological species which means that
we do not know what the full potential could be for human society.
A
biologically diverse environment is essential to human health and well-being
in many ways. It stimulates our senses with a constantly changing aesthetic
which activates our emotions and moods in a pleasurable way. The present
diminishment of that diversity and expected further losses suggest that
in a few more decades people will be seeking direct contact with nature
just so they can experience it. As well as deepening the sense of connection
with other life forms which people intuitively seek, natural areas are
also able to restore individuals to effective life functions following
periods of high stress and mental fatigue. Indeed, even the view of
nature from a window can positively influence recovery following surgery.
It
is not only that the built environments in which most of us live do
not provide sensory diversity and change in the same subtle manner as
natural settings. Within our static buildings we tend to do the same
sort of things day after day. Contrast this with natural areas where
shifting patterns and natural change constantly capture both our interest
and imagination.
One
way for more people to have daily access to the world of nature within
the built environment is to provide people with a sense of continuity
of space, and of being part of a totally dynamic living environment.
Designers accomplish this when they are free to position windows which
open the senses to living plants, and integrate indoor furnishings with
outdoor plantings.
4.
Excessive or inappropriate use of space
All
living organisms need their own evolved habitat space in order to grow,
develop, mate, disperse, andin the fullness of timespeciation
will occur such that new forms evolve to continue the interdependent
life processes. With our formidable population levels we must now find
ways to reduce our own space dependency if other living organisms are
to find the space they need to pursue their lives. Effecting positive
steps in this direction will ensure that we ourselves, and future generations,
live with the benefits of nature in full health in an ecologically sustainable
world. Learning how to adopt practices which will conserve space is
a major challenge for ecologists, designers, and all members of society
who engage in providing spaces for urban life-style activities. We will
have to set a new benchmark goal: that of minimising the individual's
space needs while maximising a ready access to nature.
In
Canberra, which is my own urban habitat, there has been a strong move
in recent years for the development of medium density housing. Designers
and government see this as an appropriate response to growing spatial
needs. But these proposals meet with strong opposition from the resident
community at large. Why? we must ask. The clear pattern of response
from Canberra residents themselves shows not so much opposition to the
concept of medium-density housing as opposition formed by adverse experiences
of this type of housing which residents had either suffered or witnessed
in their suburbs.
The
problems raised by local residents include:
(1)
inadequate ventilation reducing the quality of air indoors.
(2)
insufficient natural light in living rooms as a result of too few,
too small, or poorly positioned windows.
(3)
lack of trees, parks, and open spaces to look on to.
(4)
insufficient, and often inappropriate, places for children at active
play.
(5)
not enough parking spaces for friends, visiting family members and
other visitors.
(6)
not enough attention to noise control between the residents of medium-density
housing and surrounding areas.
(7)
loss of that fine sense of balance between privacy of private home
and desirable social interaction.
(8)
lack of appropriate provision for pets or companion animals.
The
interesting thing is that residents, in most cases, blamed the building
designers for these stressful problems. Solutions, of course, rely on
creative design. Not design according to preconceived formulas, but
design which is thought all the way through from the point of view of
people-use and environmental impact. This must be foremost in the minds
of the planner/designer rather than profit maximisation.
Budgets
and profits carry weight, but must be weighed against the costs of causing
subsequent ill-health, stress, and high anxiety in society at the same
time laying too heavy a burden for the biosphere to carry. We have been
mutely accepting what emerges from the developers and governments'
mind-sets. Their concerns are ones that can be measured, and measured
in dollar costs which everyone can understand. Our task must be to make
known the downside costs of poor urban planning and urban design. And
to make it widely known and clearly understood among developers, government
agencies, and householders alike. Armed with this understanding,
human intelligence and human integrity, at all levels of society, will
readily reject present widespread practices and seek out the healthy
life-sustaining solutions for both ourselves and for our built and natural
environments: our habitat.
The
need is pressing, as we can see by considering each of the four global
issues we have been looking at and finding them all expressed by local
Canberra residents in matters affecting them personally. However, it
is not easy for the relationship between global and local environmental
quality to be recognised by local residents anywhere in the world. But
without this recognition positive social change at the personal, local,
and global levels is unlikely to occur on a scale which is going to
check and redress the environmental degradation issues now free-running
throughout our planet, and its biosphere.
Once
the issues are recognised and understood by the public at large a coincident
set of dynamic solutions can emerge and take root. Our first task, as
I see it, is an interchange of knowledge and understanding relevant
to the global issues between the professions whose work actively impinges
on both the causes and side-effects prevailing in the environment. I
have tried to draw attention here to some of the initiatives society
could expect from ecologists and designers through a creative synthesis
of diverse understandings. Our challenge is to set up both situations
and conditions where open dialogue can take place constructively.
It
is good to record here that in Australia we already have a number of
active community-based groups learning the nature of the problems we
face. They are seeking to work together to bring about needed changes.
And they are fruitfully diverse. Landcare, Coastcare and
Waterwatch are nationally established. The Nature and Society
Forum (NSF) is a Canberra-based urban group seeking to improve understanding
throughout the community of the processes of life and of the place of
humankind in the biosphere as well as stimulate discussion and debate
between concerned and interested individuals about the relevance and
implications of this improved understanding to themselves and society
as a whole. NSF aims to create a bridge between the academic world and
the community at large, encouraging an exchange of information and ideas
on the environmental and health problems of concern to us all.
Another
Canberra-based urban community initiative is the Australian Centre
for Environmentally Sustainable Systems, known as ACESS. Its function
is to promote sustainable systems and technologies, by means of developing
a display area in the A.C.T. where the public can see sustainable technologies
at work across the range of building design, water and land management,
recycling, food production, integrated pest control, solar and wind
energy and the like. The goal is to enable people to see how appropriate
technologies are being put to work and ways of living they can put into
practice themselves.
These
are a few examples of new community organisations. They must be free
to flourish in an effective networking environment. That way new groups
will continue to form, expanding to embrace a very wide cross-section
of society. They will throw open the bridges for the free flow of information
throughout the whole community.
Perhaps
these community groups will provide the stimulus that will lead to the
prevention of further deterioration in the environment, and provide
a strong lead in its reversal.
"Unless
we change we'll get to where we're going, and faster than we think."
