Article on genetically modified foods. The
world today is on the cusp of a revolution in food, as genetic
technology promises to open up vast new opportunities in the food
industry. But there are many controversies, many unknowns. As with all
potentially sweeping technologies, this can be taken as either good or
bad, giving the question "What's for dinner?" new weight and urgency.
This article is short primer on genetically modified (GM) foods,
including its most controversial aspect, and some ethical thoughts
about their use and regulation. (Originally published in re:generation quarterly, 6.4; 2000. Edited for the Web.) (Back to Articles.)
GM Foods: Hard to Swallow
by Charles Strohmer
It is difficult, if not impossible, to overstate the importance of
food. Eating, after all, is a quintessentially human activity. Sure,
all life forms, in one way or another, get nutrients and energy from
outside themselves, but only people have transformed nutritive
consumption into such a varied, elaborate, and ritualistic process.
Feats and fasts are central to most every religion and culture. And
since having something to eat is a frontrunner for the most basic human
requirement, we need not climb much higher on the hierarchy of needs to
realize that what we eat is critically important. So when we talk about
life-changing and life-shaping technological advances, food—the
stuff that we ingest—takes center stage in our hopes and fears.
Case in point: at the end of the nineteenth century, the advent of
refrigerated rail cars made large-scale processing, packing, and
distribution of meat possible. Suddenly East Coast city dwellers were
able to dine on beef and pork that had been killed weeks earlier and a
thousand of miles away. It was an unsettling prospect for people who'd
grown up eating meat that had been butchered recently and locally. The
new technology just seemed wrong. So people reacted, and a significant
protest arose from concerned citizens who demanded the right to know
just what they were feeding their families. Eventually, the efficiency,
cost-effectiveness, and variety offered by technology won out. Today,
it's actually the idea of eating fresh-killed meat that sets many of
our stomachs to churning.
Today we are on the cusp of another revolution in food, as genetic
technology promises to open up vast new opportunities and unknowns in
the food industry. As with all potentially sweeping technologies, this
can be taken as either good or bad news: superfoods—miracle
nutrients capable of saving lives even as they make for a cleaner
environment; or Frankenfoods—well-intentioned creations that will
nonetheless prove ugly and destructive. So once again the question
"What's for dinner?" takes on new weight and urgency.
As recently as 1989, no transgenic crops were commercially marketed in
the United States. Today it is increasingly difficult to find and buy
non-genetically modified (GM) foods, and some critics speculate that
the American public has been lulled to sleep to participate in a
nightmarish experiment. But many disagree. "Genetic engineering," says
Clare Hasler, director of the functional foods program at the
University of Illinois, "[makes] foods that are already good for you
even better." Crops will be easier to grow and engineered to resist
pesticides, herbicides, and viruses. We will have healthier fruits and
vegetables. Oranges would be altered to carry all the nutrients of a
multivitamin, common foods would be engineered to reduce cholesterol,
and a brand new category we might call pharmacofoods would be created:
tomatoes that carried potent cancer-fighting substances; fruit
engineered with life-saving vaccines; soybeans genetically altered to
carry higher levels of isoflavones—helping to reduce heart
disease.
Robert B. Shapiro, chairman and CEO of the pesticide and pharmaceutical
giant Monsanto Corporation, which is the current world leader in the
production and distribution of GM foods, believes we are seeing the
barest beginnings of a revolution in agriculture, food, and,
ultimately, human health. Shapiro told Michael Specter, writing in The New Yorker,
"People want to live better, and they will use the tools they have to
do it. Biology is the best tool we have. There now exists an
opportunity to create a genuine science of nutrition, something that
has never existed in human history."
Cornell University's Boyce Thompson Institute for Plant Research is
closing in on a vaccine for hepatitis B and one for diarrhea that could
be engineered into the cells of a banana. The benefits just in
developing nations, no one would argue. Another significant advance
involves the world's most important crop, rice, which is a poor source
of vitamins. Ingo Potyrkus, at the Swiss Federal Institute of
Technology in Zurich, and colleague Peter Beyer, at the University of
Freiburg in Germany, have experimented for nearly a decade to introduce
into the rice plant three genes (taken from bacteria) that complete the
genetic pathway needed to produce beta carotene, which is then broken
down into Vitamin A. Finally in 1999, viola! Now dubbed Golden Rice
because of its pale yellow color—courtesy of beta
carotene—it would help prevent Vitamin A deficiency and its
symptoms, such as loss of eyesight, in millions of people where rice is
the main diet. Charles Arntzen, of the Boyce Thompson Institute, is
ecstatic: "This one accomplishment of genetic engineering could
alleviate more suffering and illness than any single medicine has done
in the history of the world."
It is often argued that such modification is no different from what
farmers all over the world have been doing for centuries. Genetic crop
engineering, however, bears little resemblance to traditional hybrids
and breeding techniques, which take place within natural boundaries
between closely related foods. For instance, tomatoes can crossbreed
with other tomatoes, but not with soybeans. It was the twentieth
century discovery of the structure of DNA that helped human beings make
the quantum leap from manipulating natural variation to directly
inserting genes from one species into another.
What worries many people, however, is that genetically engineered crops
and foods may alter bodily processes in fundamental ways. Once released
into the food supply, genetically engineered organisms become part of
our complex ecosystem, and there are few clues about what the
cumulative effects will be.
The introduction of new toxins and allergens into GM foods is a case in
point. In one incident, scientists at state universities in Nebraska
and Wisconsin inserted genetic threads from a Brazil nut into a soybean
plant to create a new and better protein that would be spliced into any
number of foods made from soy. Further tests before product release,
however, revealed that this food would cause severe allergic reaction,
even death, in people who were allergic to Brazil nuts. With little
regulation and even less required labeling in the U.S., the question is
being asked: how would these people have known not to eat the bread,
the pizza, the cereal, the chocolate, the ice cream, and the hundreds
of other foods processed with this GM soy? (The courts tend to uphold
the Food and Drug Administration's contention that genetically modified
foods are generally safe, and thus do not require the same labeling as
foods containing other chemical additives.)
One of the hottest legal skirmishes is over Bt corn, genetically engineered with the common soil bacteria Bacillus thuringensis
and grown on approximately twenty million acres in the U.S. Because
widespread use of the corn may wipe out the effectiveness of Bt on
pests, hurting organic farmers who rely on it in place of pesticides, a
coalition of 70 plaintiffs has filed a lawsuit to halt Monsanto's
distribution of Bt corn. Also this autumn, a Kraft Foods recall in
September of its Taco Bell brand taco shells snowballed into a
nationwide recall affecting many restaurants and supermarket chains and
covering nearly three hundred varieties of tacos, tortillas, and snack
chips. Tests confirmed that the products were made from a genetically
engineered corn called StarLink (made by Aventis Crop Science), which
was approved by the Environmental Protection Agency in 1998 for use
only in animal feed, due to concerns that the corn may cause allergic
reactions in some people. Both cases underline the increasing potential
for unexpected paths from manufacture through supply and consumption
and the need to identify checkpoints to implement tighter controls.
But, suggests Hope Shand, research director of RAFI (Rural Advancement
Foundation International, a Canadian environmental organization), all
of this is small potatoes compared with "terminator technology." The
terminator, or suicide, seed—developed jointly by the
Mississippi-based Delta & Pine Land Seed Company, Monsanto, and the
USDA—has been genetically altered to sprout an infertile plant,
one unable to produce viable seed. Such a crop could be harvested and
eaten, but its seed could not be replanted. (It couldn't produce
another crop.) If this were the only kind of seed available in the
future, then farmers, collectives, and even home gardeners would be
forced to purchase new seed every growing season.
On a global scale, this technology could be "terribly dangerous," says
Shand. "Half the world's farmers are poor and can't afford to buy seed
every growing season." Yet patents are pending with several biotech
multinationals, including Monsanto and AstraZeneca, to experiment with
terminator seeds in the developing world, where farmers grow about 15
to 20 percent of the world's food and depend on their "saved seeds"
(seeds that reproduce) for next year's crops. Although the biotech food
multinationals say not to worry, some analysts argue that developing
nations will be ruined not only by the economic but also by the moral
and social costs of dependence on terminator technology.
Although not reported much in the U.S. media and press, professional
ecologists, environmental lobbies, and many public and private agencies
around the world recognize the national security issues latent in
terminator seed technology and they are calling for their governments
to stop sponsoring it and to eliminate it. Due largely to tremendous
and concerted European activism during 1999 (despite staunch support
for GM foods from many European Community governments), Monsanto
announced a commitment not to commercialize terminator or other sterile
seed technologies. Critics remain skeptical, saying that Monsanto and
the other biotech firms have merely hunkered down until the dust
settles. "This is a patent that really turns on the greed gene," says
Camila Montecinos of the Chilean-based Center for Education and
Technology. "It's too profitable for companies to ignore."
So what's a hungry person to do? The issues are complex and there's
little to be gained in villianizing either the scientists, who are
hoping to use their skills to feed the world's hungry, or the
corporations, merely because they stand to profit immensely from such a
feast. But for many who are justly concerned about the risks associated
with GM foods, a policy of informed, strategic complaint may offer a
good stop-gap solution. Policy reversals in Europe may be indicative of
how the GM food controversy could play out in North America. Some
nations, like France and Italy, where television ads decry GM crops and
foods, have moved to ban planting GM corn. And sustained public outcry
has prompted thousands of European supermarkets to remove GM foods from
their shelves. Denmark, Switzerland, and Norway require labels on GM
foods, and the European Agricultural Commission now requires labels on
all GM seeds, grains, and animal feed.
Such moves are cause to celebrate for those who for political,
socioeconomic, or environmental reasons find GM foods unsavory at best.
At present in America the debate is deeply divided between
reactionaries fleeing the complexities of a new technology and the
scientists and businessmen who think that what they're doing really is
good for humanity (or at least isn't harmful). In Europe, a third way
is being pursued called the "precautionary principle," which (in its
narrow interpretation) urges that even remote risks from GM crops and
foods be given more weight than any possible benefit. Too narrowly
interpreted, however, the precautionary principle could stall any
progress because it would preclude marketing to foods unless the
outcome was absolutely guaranteed in advance. A wider interpretation
could foster humane progress while ensuring safety before profit.
Evolving a synthesis for a just third way to be pursued for the entire
world community will also mean overcoming a universal problem.
Throughout human history, our knowledge has often outstripped our moral
sensitivity. As British theologian and philosopher John Peck says, "At
the back of our fear of GM food technology is that human beings can't
be trusted with it." The technology itself is not bad, notes Peck, but
"as Christians we must bear testimony that knowledge is not a god, not
an end in itself, but that the search for it has a responsibility to
God and the moral conscience. It sounds heretical today to say this,
especially in the scientific community, but if we took this
responsibility seriously, it would mean saying ‘no, we're not
going there' to certain expressions of technology unless we can agree
on a transcendent moral authority by which to control it. And to some
technologies, we may simply need to say no, full stop."
Religious, or ultimate, beliefs also ought to be an aspect of a
third-way paradigm, and they are actually shaping some boardroom
decisions. When asked why he had decided to stop using GM ingredients
in Gerber baby food, Novartis chairman and ceo, physician Daniel
Vasella (Switzerland's best-known corporate leader), told The New Yorker,
"We are not missionaries. We sell things. No company can prosper by
telling customers what is good for them.... This is not just about
plants. This is about our myths, our history, our culture. It's about
what we put in our mouths and in our babies' mouths.... What is more
basic—and what could be more frightening—than playing with
that? Of course it scares people. How could something so important not
scare people?"
A theology of food is ultimately one of where (and in whom) you put
your trust, and how you handle your fears. There are no hard and fast
rules. If you're Joseph in Egypt, the faithful thing to do is to build
storehouses for your nation's grain. To the rich merchant of Jesus'
parable, however, the one who's life was to be demanded of him that
very night, bigger barns are of no value. For the Israelites wandering
towards the promised land, a strict set of dietary laws was just the
thing to promote obedience to God and to set them apart from other
cultures. But for Peter, daydreaming on a rooftop in Joppa, every sort
of food was declared clean, for God's greater purpose of revealing
Christ to all the earth's people.
The immense promises and purposes bound up in the development of
genetically modified foods provoke questions of trust and fear that cut
both ways. Unwise though it may be to blindly trust in the goodness of
a GM-food-fueled human future, it is also naive to fear the future by
placing a similarly blind trust in the good old days before all of this
cropped up. Ultimately, no technology should be trusted more than God;
but neither should any future (genetically modified or other) be feared
more than God. Food is vital, but at least theologically, the maxim
"you are what you eat" is misleading at best. (Published in re:generation quarterly, 6.4; 2000. Edited for the Web.)
