As high winds whipping along the
Pacific coast bounced and shook the small
propeller plane, I tried to concentrate on my
reason for flying to Santa
Barbara. I was on my way to interview Garrett Hardin,
microbiologist and human
ecologist, most widely known-notorious even-for his 1968 essay,
"The Tragedy of
the Commons," in which he describes the follies of overpopulation.
I was
five months pregnant, and given Hardin's views on population control and
prophecies
concerning the fate of the environment, I dreaded his response to my
condition. To my
surprise, the reputed harshly opinionated and fiery aspects of
his personality had been
greatly exaggerated-I suspect by his many critics.
Instead, I found a gentle man suffused
with a love of nature, family, and
classical music. Despite his 77 years and a polio
handicap, Hardin swims laps
daily at his Santa Barbara home, which has become a haven
surrounded by giant
eucalyptus and dense chaparral.
Stronger than his determination to
exercise vigorously, however, is his
relentless 40-year challenge-in many books, papers,
and lectures-to conventional
social ideals. His latest book, Living Within Limits
(released by Oxford
University Press this fall), further explores the concept that
unrestrained
reproductive growth throughout the world threatens to wreak widespread social
disorder.
Born in 1915, Hardin grew up in the Midwest where his father's job with the
Illinois
Central Railroad moved the family from one town to another. Even
though they never settled
in one place, he found a sense of constancy at his
grandfather's farm near Butler,
Missouri. Hardin got his degree in zoology in
1936 at the University of Chicago, where he
studied under W. A. Allee. At the
time, the birthrate in the United States was declining.
Books and articles
prophesied the end of civilization, the extinction of the human race.
But
Allee, a professor of ecology, was virtually alone in insisting that the decline
was
temporary, a mere blip in the population curve. The birthrate, he
maintained, would soon
start going up again. "So early in my training,"
explains Hardin, "I was influenced by an
unpopular theory. Alone with a small
group of biologists, I was concerned about future
population growth "
After completing a Ph.D. in microbiology at Stanford during World War
II, Hardin
worked for the Carnegie Institution of Washington's Division of Plant Biology on
the Stanford Campus, investigating how algae might be used for antibiotics and
as a
possible human food source. In 1946, he left the project. "The more I
thought about
producing algae for food," he remarks, "the less use I saw in the
research." Developing new
food sources would only encourage continued population
growth.
Hardin was also influenced by
Thomas Malthus, who in 1798 wrote that food would
be the limiting factor of population
size. When food resources were depleted,
Malthus claimed, chaos and massive suffering
would ensue, halting population
growth. "Malthus was correct when he said there will be
limits to increasing
population, but wrong about what the limits would be," says Hardin.
Since
Malthus' prediction, per-capita production of food has increased dramatically in
the
world. "Overpopulation causes other obstacles," adds Hardin. "We've plenty
of food, but
we're wasting an awful lot of time trying to go anywhere." Hardin,
like Malthus, suspects
that if population growth continues at its current rate,
chaos will ultimately ensue.
The
same year Hardin left the algae project at Stanford, he accepted a teaching
position at
what is now the University of California at Santa Barbara to teach
biology, genetics,
evolution, and later human ecology. Retired in 1978, Hardin
continues to stimulate debate
and provoke controversy with his far-reaching
ideas about the human condition.
Omni: In
your 1972 book, Exploring New Ethics for Survival you said you feel
as if you are "living
in the eye of a hurricane waiting." What did you mean?
Hardin: I'm impressed with the
reluctance of society to confront certain
issues, and the ingenuity people show in
developing a rhetorical defense against
controversial concerns. We don't budge from our
positions. Everyone has a
computer in his head that does a lot of work on its own. Many
difficult
conflicts are worked out at a subconscious level. When we run into a roadblock,
the conflict is intercepted by the in-house computer and prevented from coming
to the
conscious level. Any thought brought to the surface is in a censored
form. We look only
for certain answers, closing our eyes to the possibility of
others. This is the roadblock
for all discussions of population.
Our censored view about population is reflected in the
widely accepted
"child-survival hypothesis." In a primitive community where couples have
too
many children and large numbers of them are dying, supporters of the
child-survival
thesis believe we can reduce infant mortality by sending these
people the best modern
medicine. Obviously, the first effect of reduced infant
mortality is an increase in the
rate of population growth. But, according to
this theory, couples in Third World countries
have so many children because so
many die. A high birthrate is a safety measure to ensure
some children's
survival. So if child mortality is reduced, these people will supposedly
eventually reduce their fertility.
The hypothesis is true in a sense: People do diminish
their fertility somewhat.
But the result is nevertheless an increase in the number of
people that reach
age 20. Fewer are born, but more reach adulthood, providing the next
generation
of breeders. So the population does not decrease and the hypothesis isn't
really
true,
Why do we continue to practice the child-hypothesis theory? Because we are
tenderhearted.
We'd feel terrible if we didn't let others know there are ways
to prevent infant
mortality. So international Planned Parenthood generally
provides medical assistance to
reduce infant mortality in Third World countries.
We think if we do the right thing-save
babies-population control will happen
spontaneously.
Omni: In 1967, Paul Ehrlich's
Population Bomb prompted the formation of the
organization Zero Population Growth (ZPG).
Was this an effective move toward
better understanding of population problems?
Hardin: The
policy of ZPG has a fundamental weakness. Like the founders of
Planned Parenthood, the
members of ZPG were determined to enable women to have
the number of children they wanted
when they wanted. They believe if women are
made aware of the importance of reducing
population, ultimately they will want
fewer of them. But women who want large families
will have them-there's no way
to tie their individual wants to national needs without some
sort of coercion.
I saw ZPG headed for failure. But still, it was a step in the right
direction
for helping to change the climate for population control.
ZPG also had another
problem. To put it exceedingly bluntly and in prejudicial
terms: In general, people who go
to college are more intelligent than those who
don't. It would be better to encourage the
breeding of more intelligent people
rather than the less intelligent. ZPG's entire
attraction has been among the
college population. So in effect, ZPG is encouraging
college-educated people to
have fewer children instead of encouraging reduced fertility
among the less
intelligent.
Omni: Writing "The Tragedy of the Commons" was very difficult,
you've said,
because "I was reaching conclusions that repelled me and tried desperately to
avoid them."
Hardin: The basic concept of that essay was first published in 1833 by the
mathematician William Foster Lloyd. He wrote that if a community purse is made
available
to the public, someone will spend a crown more quickly without
thinking than if the crown
comes from that person's own purse. Lloyd also said
that public land is like a public
purse: If everyone can dip into a common
pasture, then that land will be abused. The
pasture on private land will be
protected by the owner and not overgrazed, so it can be
used year after year.
Rather than focusing primarily on a common purse, I concentrated on
a common
land, common pasture, and developed my essay from there. I tried to show how
reproductive
freedom, like a common pasture or community purse, is abused.
People are allowed to have
as many children as they choose without complete
responsibility for their care. Society
carries the extra burden parents can't
undertake.
I kept coming up against a conflict with
the idea of individual freedom-that
each should do whatever he or she wants and everything
will be all right. This
is widely believed in Western civilization where individualism has
been
successful in so many other areas, particularly free enterprise. Laissez-faire
economics
permits an entrepreneur to price his goods any way he wishes. On the
free market, the
person pricing his products too high will go broke because he
doesn't sell enough; the
person selling too low will also go broke because he
doesn't make a decent profit.
Eventually prices balance out. By and large, this
is the way the free market works, and
it's a good system.
In writing "The Tragedy of the Commons" I resisted giving up the idea
of
applying the principle of laissez-faire economics to population control. Can a
free
market be applied to how many children a couple raises? Unfortunately,
because some of the
expense of having children is born by society, there is not
sufficient pressure on the
couple to have only the number of children they can
take care of. So unlike the
equilibrium obtained in the free financial market,
a laissez-faire system of parentage
yields too many children, too poorly taken
care of. I finally gave up the idea that
free-market principles could be used
to control population.
Omni: Haven't a number of
people criticized the validity of the concept
embraced in "The Tragedy"?
Hardin: Sure.
One argument claims that a community of lobster fishermen who
fish off the coast of Maine
functions as a successful commons. "Therefore Hardin
is wrong!" my critics say. What these
skeptics miss is that this commons of
lobster fishermen has only a few members. They take
as much lobster as they
want, but the commons is not depleted. A commons only works
successfully when a
restricted number of people dip into its resources. Numbers become
very
important.
The example I frequently cite is a successful communistic group of religious
farmers, the Hutterites, in the northwestern U.S. and Canada. They are
disciples of the
Marxist principle, "To each according to his needs," where a
general pot is provided for
the entire populace. The Hutterite society has
found from practical experience, however,
that the Marxist concept doesn't work
if the community grows beyond 150 people. People
start going astray, stop doing
their share of the work.
To resolve this problem, when a new
community of Hutterites forms, its members
immediately lay plans for splitting into two
separate groups. They buy another
farm as soon as they can; when the community grows over
150, they divide into
two villages with the same number of old, young, and workers. The
Hutterites
can't make a commons work over 150. So to my critics I say, "A commons doesn't
work if it's made up of too many people, even if they are good." With today's
growing
populations, the possibility for a successful commons becomes less and
less likely.
Omni:
Yet you've also frequently argued that there is no such beast as a
global population
problem.
Hardin: True. Roads all over the world have potholes. Now suppose that
people
suddenly become concerned with "the world pothole problem" and as a
result set up the World
Pothole Commission to fix the widespread potholes.
Would you get the pothole in front of
your house fixed faster by a local county
agency or a world agency? We'd never get those
potholes filled if we depended on
a world authority to do it. Potholes are not a global
problem and should not be
considered globally. Population isn't a global problem either.
It is produced
in each bedroom; a very local activity produces it, and so the control of it
needs to be local.
Many of my critics believe people of Third World countries can't handle
these
issues and need outside help. Certainly they can be given information about
birth
control from other countries, but to give them food or money is a mistake.
This is the
commons again: If they don't have to pay for it themselves, they
won't use it wisely.
Sending
food to Ethiopia, for instance, does more harm than good. Each year the
production
obtained from Ethiopian land declines. The lands are used beyond
their carrying capacity
because there are far more people than renewable
resources. Overproduction occurs.
Eventually the soil loses its nutritional
value and forests are stripped bare, causing soil
erosion and severe floods.
The more we encourage population growth by sending more and
more food, the more
damage is done to the production system. Every time we send food to
save lives
in the present, we are destroying lives in the future.
Most conventional ethics,
such as "I am my brother's keeper," work only where
small numbers of people are involved.
Those who initially formulated these
ethics I suspect never conceived of a time when people
in the U.S. could see
others starving to death on TV in "real time" on the opposite side of
the world.
We must realize our ability to know what's going on in other parts of the world
far exceeds our ability to do anything about it. Conventional ethics sound good
but don't
work when the scale is enlarged. It works in the village, not in the
whole world.
Our best
chance of solving these problems is to let each country produce as many
babies as the
government decides is appropriate. This means each country must
take care of the babies it
produces. No rich country should be an escape hatch
for a poor country.
But then no nation
is really poor. If it has a small enough population, it can
be rich. Bangladesh, for
instance, is a rich country. It's the same size as
Iowa. But 115 million people live in
Bangladesh, while Iowa supports 3 million.
If Bangladesh had 3 million citizens, its
people would be living in the lap of
luxury. Only one crop can be grown annually in Iowa,
whereas in Bangladesh, two
or three can grow each year. There's no reason for starvation
to occur in
Bangladesh. It's a much richer country than Iowa, but not with 115 million
people.
Omni: What form of population control do you favor?
Hardin: Well, the one that sounds
the nicest was raised by Charles Darwin's
grandson, Charles Galton Darwin. He said
increase people's expectations so they
don't think they're living the good life unless they
have a motorcar. Use the
automobile as the symbol for personal luxury. Reduce fertility
by pointing out
advantages of not having such large families.
The quickest, easiest, and
most effective form of population control in the
U.S., that I support wholeheartedly, is to
end immigration. Our population
growth would be spontaneously controlled. The U.S.
accepts more immigrants each
year than the other 179 nations of the world combined.
Economist
Kenneth Boulding suggested that at birth, every female in the country
be endowed with a
certain number of green stamps giving her the right to have a
certain number of children
when she reaches child-bearing age. Depending on the
population, the value of these stamps
may vary from year to year. Let's say one
year each woman is entitled to one and
eight-tenths green stamps. If a woman
wants to have one child she can sell the
eight-tenths to somebody else. If she
wants two children, she has to enter the market and
buy two-tenths more stamps.
This could work in any country.
Omni: What is your opinion of
China's population policy, which prohibits
couples from having more than one child?
Hardin:
I give the Chinese credit for officially recognizing that they have a
problem and for
having the nerve to propose the single-child program. China is
the only country in the
world that recognizes it has too many people. They have
failed, however, by not making
this directive universal throughout the country.
The one-child policy is only enforced in
congested urban areas. People in rural
regions continue to have too many children. So the
Chinese haven't solved their
problems at all.
Omni: Will population control cause other
problems in Chinese society? Might a
single child truly become what they call "a little
emperor"?
Hardin: The Chinese admit their children are being spoiled, but this is
natural
behavior. I don't see any particular difficulty developing because less
babies are born
there. On the contrary, a smaller population should contribute
to a better quality of life
in China.
As for too many old people, the existence of a dominant elderly populace is not
a serious danger anywhere. If an excess of young people exist, the older
members of
society are encouraged to retire early. When a deficiency of young
develops, the elderly
will be urged to work longer. This process automatically
adjusts itself. How much and for
how long a person works before retiring
depends on the community.
Omni: Infanticide as a
form of population control is hard to accept, yet you
support it in its historical context.
Hardin: Yes. Looking at history with an open mind you'll see that infanticide
has been
used as an effective population control. In writings about the South
Seas, Robert Louis
Stevenson expresses astonishment that island peoples
practiced infanticide and yet were
unusually loving towards children. Stevenson
came from Calvinistic Scotland where, by God,
children were treated severely.
The Scots would never think of killing a child, but they'd
never pamper it
either. In the South Seas, the reverse occurred. In all societies
practicing
infanticide, the child is killed within minutes after birth, before bonding can
occur. The mother never nurses the child. The South Pacific peoples must have
easily seen
the problems associated with overpopulation. When you live on an
island, you know you live
in a limited world.
Through most of history there's been no need for concern about
population
control. Nature would come along with epidemic diseases and take care of the
matter for us. Disease has been the primary population controller in the past.
Because
widespread disease and famine no longer exist, we have to find another
means to stop
population increases.
Omni: What scenarios will unfold if world population growth
continues at its
current rate?
Hardin: Some organizations have done the proper demographic
analyses and have
the best answers for the future. Usually I quote one of these
projections. Now
having said that, I'll go a step further and say that I don't have
confidence in
these projections. The pressures from expanding populations will become so
great that trends will change. I suspect disasters such as widespread famine
will prevent
us from reaching the projected numbers.
I reluctantly make this statement because people
say, "Oh you cruel man, you
want to kill people." I don't want to kill anyone; but clearly,
crippling
conditions already exist in parts of the world due to escalating populations.
People
in central Africa suffer greatly from the effects of overpopulation; the
land has been
stripped of vegetation, causing erosion and flooding, leaving
little hope for new crops.
These countries may yet face a worse disaster, in
the spread of AIDS.
Omni: In the early
Sixties you writing and lecturing about population and
decided to speak out in favor of
abortion. Why?
Hardin: First, I didn't want to fight two battles at once. I didn't want
people to oppose population control if they were not in favor of abortion. It's
quite
possible to be against abortion and still be in favor of population
control. Until the mid
Fifties, I strongly opposed abortion. Then in 1958, I
read Abortion in the United States,
an account of a conference of doctors and
Planned Parenthood professionals.
I'd always
thought abortion was an extremely dangerous operation. Reading this
book, I discovered
abortions, when performed by competent medical professionals,
were only one-fourth as
dangerous as normal childbirth. (Today a normal
childbirth is ten times more dangerous.)
Other evidence presented at this
conference suggested that having an abortion was a
psychologically sound
procedure, less harmful mentally for a woman than being compelled to
have a
child she didn't want. By 1962, I'd moved around to the other side and became a
strong
supporter of legalized abortion. By spring 1963, I was ready to go
public with my ideas.
Certainly the time was right for me to speak out on
legalized abortion.
Omni: The Supreme
Court decision legalizing abortion in 1973 stated, "The
unborn have never been recognized
in the law as persons in the whole sense." Why
is this significant?
Hardin: The argument
for and against abortion today encompasses this very
issue. Is a fetus a person? Are all
lives equally valuable? Biologists don't
believe all life has the same worth. In many
instances, qualification is
important. Evidence is clear in nature. About 50 percent of
all conceptions in
mammals perish before birth. By having fewer offspring, mammals are
able to
take better care of their young. The conceptions that perish are virtually
without
value; if they persisted, the continued existence of the species might
be jeopardized.
This
happens with humans as well. About half of all pregnancies are lost the
first few days
after conception. If people say that an embryo is a human being
from the moment the sperm
enters the egg, then all laws applying to humans must
apply to this tiny embryo. This
fertilized egg has to be buried with all the
expenses applied to a person who dies.
Suppose a woman thinks she's pregnant
because she's missed her period. A week later she
gets it and says, "I guess I
was just late." Maybe she wasn't late; maybe she was pregnant
and had a
spontaneous abortion. In such cases-if the conception might be "life"-whenever
a woman is late with her period, the menstrual products will have to be
collected and given
a proper burial. If people want to change the law and
declare that a human is present from
the time the sperm enters the egg, they
must face these consequences.
A fetus is of so
little value, there's no point in worrying about it in a
society where over-not
underpopulation is a problem. We don't need to chase
after every last one of these
embryos. Like the blueprint of a house, a fetus
doesn't have the same value as the house
itself; it is not a human being. Just
like 10,000 acorns; the loss of these seeds would be
not be considered the loss
of 10,000 oak trees, or deforestation. If a woman wants an
abortion, either
because of poverty, poor health, or because she doesn't think she will be
a good
mother-whatever reason-it's not in society's interest to urge her to have the
child.
We have enough poorly taken care of children already; we don't need any
more. If a woman
says she doesn't want a baby, that should be final.
Omni: What might happen if Roe v.
Wade is reversed?
Hardin: It's difficult to predict history, but I can see no good
resulting
from forcing women to have babies they don't want. Many who oppose legal
abortion
condemn women who have them as selfish and immoral. I urge people to
forget about the
problems these woman may face and instead consider how
reversing the right to have an
abortion might affect them. The cost of raising
these children will sooner or later reach
the general public. As taxpayers, do
they really want to support an unwanted child?
Studies conducted in Europe show
unwanted children have more psychological, educational,
and health-related
problems than children born to women who want them. It is paradoxical
that
people who call themselves conservatives oppose abortion. Conservatives usually
strive
to avoid taxes and high expenses. And yet, by opposing abortion, they
ultimately ensure
higher taxes. They should be the last to condemn abortion.
Omni: After the 1973 Supreme
Court decision, why did you stop lecturing on
this topic?
Hardin: We had essentially won
the battle, or so we thought at the time. I
decided I could go back to talking about
population and its effects. When I
first started lecturing on abortion, so few people were
talking about it, I
figured I was needed even though I was a man. But I was relaying
secondhand
information. By the early Seventies, women were speaking out on their own. If
anything needed to be said about abortion, women could say it better.
Omni: Might you
start speaking out regularly again?
Hardin: It's possible. Whether I start defending Roe
v. Wade depends on what
happens-on whether I get so riled up enough, so irritated that I
can't stand
being silent.
