While almost every new technology brings with it debate over its benefits,
the recent introduction of genetically modified, or GM, foods into the
marketplace has generated a controversy which seems to intensify almost
daily. In Europe, for instance, there is now a moratorium on approval
of new GM seeds, and major supermarkets and food retailers there are either
clearly labelling or refusing to carry GM food products. Closer to home,
some estimate that GM products can be found in 60 per cent of the food
on Canadian grocery shelves, a statistic that seriously alarms the North
American green movement. Consequently, it is now working to bring the
European perspective to our shores, led by cultural heavyweights like
Canada's pre-eminent "green" scientist and TV host, Dr. David
Suzuki.
The pressures of this debate are nowhere felt as much as they are on
North American farms, and within the boardroooms of the companies that
develop these products. As a result of the negative publicity over GM
foods, many farmers are deciding to cut back, or not even grow, GM crops,
apparently believing that if they concede to the greens the controversy
will go away. Nothing, however, could be further from the truth. The attack
on GM crops is only a small part of a larger green assault on technological
advances, property rights and the freedom to innovate in general. A victory
here will only signal to the greens potential weakness on the part of
their adversaries, encouraging them to move on to the next "hot"
issue, whether that be conventional farm chemicals, livestock practices
or whatever.
The controversy over GM food owes much of its life to the innovative
way in which GM seeds are developed. Most of us are familiar with conventional
plant breeding, in which plants of the same species are selectively crossbred
with each other in order to develop new varieties with more desirable
genetic traits such as increased yield or hardiness. Genetically modified
seeds, on the other hand, gain their desired traits by having genes from
often totally unrelated organisms inserted into them. For example, corn
varieties have been created that are genetically resistant to certain
insect pests, with the help of genes from a particular bacterium. Canola
seed and soybeans have also been genetically altered so that the crops
can be sprayed with certain non-selective herbicides that will kill all
undesired plants at once. Genetic modification has been applied to other
crops such as potatoes and tomatoes, and the biotechnology revolution
shows no signs of running out of species to modify.
The major advantage of GM technology is that it allows seeds to be tailor
made to suit very specific conditions. Spraying a crop with a non-selective
herbicide is generally cheaper and avoids having to possibly spray the
crop with conventional chemicals several times over. Similarly, corn and
potatoes that are modified to resist insect pests do not have to be sprayed
with more costly chemical pesticides.
Opponents of GM foods liken these products to a dangerous genie in a
bottle. Unless the development process is arrested, they feel that unpredictable
chain reactions may occur. Some have claimed that wild GM seeds will soon
pollute the countryside with unwanted and unstoppable plants. Others claim
that GM plants will spawn "superbugs" that will devastate our
environment. Still others suggest that GM crops may kill off beneficial
insects. Regarding the first claim, any stray GM plants can be readily
killed off with conventional herbicides, and as for choking out native
vegetation, most man-made plants are far too uncompetitive to do this.
Without careful tillage, fertilization and management, they simply will
not flourish in untended wild surroundings. As for the second claim, conventional
crop protection products have already generated herbicide-resistant weeds
and pesticide-resistant insects in some instances. The solution? Careful
herbicide and pesticide rotation and further product development.
The third claim arose as a result of a Cornell University study which
noted some damage to Monarch butterflies feeding off other plants coated
with the pollen of GM corn. Nonetheless, the idea of toxic pollen clouds
killing off vast populations of butterflies seems ludicrous. Research
at the University of Guelph in Ontario showed that nearly all pollen grains
travel less than ten metres from a typical corn field. In any case, the
criticism seems highly ironic considering that the alternative to GM corn
is to spray it with conventional pesticides, most of which could also
kill Monarch butterflies.
The other prominent controversy surrounding GM seed is its financial
cost. Companies that develop it, often at considerable expense, do so
because they are given patent protection for their efforts. Farmers that
use their seed sometimes pay royalty fees to do so. Furthermore, they
may have to sign contracts (technology use agreements) that may restrict
them to using only the company's herbicides on the crop, and prohibit
them from saving any part of their crop for use as next year's seed.
Many critics, in the green movement and elsewhere, view these agreements
as nothing short of techno-serfdom. In a wider context, however, there
is nothing particularly unusual about such practices. The current legal
wrangling over alleged unauthorized use of GM seeds is no different in
principle from disputes that arise over the unauthorized use of computer
software or audio and video tapes. As a possible means of cutting back
on the need for litigation, "terminator" genes have been developed
which cause seed to become sterile after one season, making them suitable
only for processing and not for seed. Ironically, such terminator genes
have been roundly denounced as furthering the goal of enslaving farmers.
What is most bizarre about such claims is that this appears to be the
first time in history that slavery was adopted voluntarily. After all,
no one forces any farmer to use GM products. They are free to use a whole
host of more conventional plant varieties and pesticides, or grow crops
organically without the use of chemicals at all. When producers choose
to use GM seed, it is not because they are deluded, ignorant fools. They
make that choice because the cost of GM seed compares favourably with
the costs of increased pesticide use associated with conventional seed.
In other words, they use it because it adds to the productivity of their
farming operation, and would drop such products if the benefits did not
materialize.
Genetically modified seeds no more "enslave" farmers to biotech
companies than modern tractors "enslave" farmers to the tractor
producers, as opposed to the allegedly carefree days of farming with horses.
Indeed, the arrival of the farm tractor long ago probably sparked widespread
fear of a loss of independence by farmers in the area of motive power.
After all, most farms were self-sufficient in horses. Their food could
be grown on the farm, and if you needed another horse all you had to do
was breed one. Conversely, tractors could not be made very easily by farmers,
and if you bought one you were compelled to purchase repair parts from
the company that made it and gasoline from the oil companies. Slavery?
Hardly. The enormous productivity gains made possible by the advent of
mechanized farming easily justified the higher capital costs. Should the
green movement succeed in their goal of forcing GM crops out of existence,
farmers will suffer enormously by being denied access to such tremendous
productivity tools.
To the greens, however, such considerations are immaterial. The attacks
on technology use agreements and the freedom to develop and trade genetically
altered crops are part of a much more comprehensive vision for the greens.
They see property rights and private, consensual contracts as dangerous
institutions that are inherently incompatible with the goal of preserving
the environment, despite the fact that the nations with the least respect
for property rights, such as the former Soviet Union, generally have the
worst records on environmental protection. This is a principle reason
why the green movement will not be appeased and silenced with a ban on
GM products. For them, GM products are only round one.
Unfortunately, it must be conceded that at present the green movement
is winning that round, and largely by default. The reason is that proponents
of biotechnology, while able to marshall excellent economic arguments
in favour of their position, rarely focus on the moral issues at stake.
Until they do, average citizens are very unlikely to defend a product
that they feel might make sense economically, but about which they feel
ambivalent about or hostile to on moral grounds.
The primary moral issue centers mainly around public safety. As noted
in this discussion, the green movement seriously lacks any sound evidence
that genetically modified foods are harmful, and what concerns they do
have are either contradictory or seriously misplaced. Their proposal to
ban GM products thus rests on a skepticist argument: the notion that GM
products might be dangerous to public health, and that even the most rigorous
testing could never prove otherwise. After all, they might point out,
a lot of scientists thought thalidomide was safe, and they turned out
to be wrong.
Philosophically speaking, an appeal to skepticism is an invalid argument.
The green movement relies on acceptance of its skepticist view to allow
them to make any claim they want, no matter how outrageous or speculative,
while hoping that their opposition will burden itself with the unenviable,
and impossible, task of proving them wrong. Rather than accept this burden,
and find themselves pointlessly trying to explain how GM foods are not
like thalidomide, proponents of GM products should insist that the greens
provide evidence for their claims before the debate proceeds any further.
If someone accused you of stealing their car on the premise that you might
be a thief, what would you do? Demand proof of the allegation, or waste
your time trying to prove you didn't do it? The grave danger with granting
skepticist arguments even a shred of validity is that they could potentially
stonewall any and all technological innovation depending on the technophobe
flavour of the day, depriving society of countless life-enhancing technological
improvements that better our lives.
As for evidence of the benefits of biotechnology, not to mention synthetic
fertilizers and pesticides, we need look no further than the fact that
these products have made possible vast increases in the quantity and quality
of food grown on a shrinking agricultural land base. The health of the
world's population has been dramatically improved by the fact that more
nourishing food is more widely available now than at any time in the past.
That in itself should give pause to calls for banning GM foods, or, as
many green activists ultimately desire, banning foods grown with any synthetic
products.
Having farmers return to the crop production methods, and therefore the
yields, of fifty years ago would be immoral from the perspective that
human beings deserve the opportunity to develop, market and purchase innovations
that steadily improve their health and nutrition. Ironically, not only
would such measures wreak havoc with the ability of world to feed itself,
they would ravage the very ecosystem so precious to the greens. As biotech
researcher Dennis Avery of the Hudson Institute points out "...mandatory
organic farming worldwide would cut yields in half and force people to
plow down at least ten-million square miles of today's habitat...".
A final, critical element in the defense of GM products is a defense
of property rights. The relatively new idea of owning a plant variety,
and setting conditions and prices for its use is no more abominable than
owning a house, a car, or a herd of cattle and doing the same thing. In
fact, should the process of unencumbered bargaining in the marketplace
for GM crops be interrupted, the result will inevitably be that the products
will no longer be made available, for the reason that there is no financial
incentive for anyone to do so. Taking away this financial incentive is
key to the green strategy against GM crops.
If we care about steadily improving the quality of our lives and, indeed,
about the legitimate needs of the environment, we need to be forthright,
and not apologetic, about the tremendous value that agricultural technology
creates. We cannot allow the green movement, with its chaotic fog of ideas,
to silence that source of progress with hysterical claims and ill-considered
prescriptions for change.
