‘Winners and Losers in the GM Debate’
Presentation by Dr Eva Novotny, Scientists
for Global Responsibility
Introduction
As individuals, we shall all be either winners or losers, and some of us might
be a mixture of both. But we can also ask what the future portends for various
groups of people:
Consumers
Farmers
Scientists who do research on genetic engineering
The Government
GM seed companies and their shareholders
We shall examine the prospects of each of these, dwelling on the first two
(consumers and farmers) but touching only briefly on the others.
Consumers
Health is a prime consideration
--------------------------------------------------
If genetic modification of our food can improve our health, we shall certainly
be winners on this score.
Let us begin with nourishment. The fundamental basis of our health is the
basic building blocks we supply to our bodies for maintenance and repair. These
must be derived from our food. There is at present no GM food that has an advantage
in terms of health over conventionally produced food, i.e., food produced with
the use of chemical fertilisers, pesticides and herbicides. Plans for a ‘Golden
Rice’ containing elevated content of Vitamin A seem to have dwindled away
Even if it is developed, an adequate amount of vitamin A could be obtained only
by eating several kilogrammes of the rice. A GM ‘Potato’, with a
one-third increase in protein content, has come into the news. Yet it hardly
seems worth the trouble of creating a new variety to boost protein content by
about 1 gm, a negligible contribution to the daily requirement. Genetic engineering
is not the only answer to producing new varieties with dramatic performance
For example, Uganda has used traditional breeding to produce, in a few years
on a small budget, a virus-resistant sweet potato that increases yields by 100%.
The virus is one that was said to be ‘a problem that cannot be solved
through conventional breeding1.’ A non-GM rice containing elevated levels
of vitamin A, zinc and iron has recently been developed by traditional breeding
methods in the Philippines2.
A crucial factor in determining the amount of minerals available in a food
plant is how much of the minerals are contained in the soil in which they are
grown. Chemical farming, whether conventional or GM, continually takes out a
wide range of minerals from the soil, but puts back only a small number like
potassium, nitrogen and phosphorus. This ‘mining’ leads to progressive
deficiency of minerals supplied in the diet. The degradation of minerals in
the soil, during the lifetimes of many of us, has been dramatic. During the
51 years between 1940 and 1991, the amounts of calcium, magnesium, iron and
copper in our vegetables, fruits and meats declined by as much 75% or even 96%.3
GM crops cannot restore these elements; they must come from the soil. Levels
of vitamins A and C have also declined dramatically.4 Wheat has lost most of
its protein since 1900.5
Medical researchers found that ‘exposure to herbicides and fungicides
resulted in significantly increased risks for NHL’ i.e., non-Hodgkin’s
lymphoma, a form of cancer. They also said that ‘glyphosate deserves epidemiological
studies’6 Glyphosate is the principal ingredient in Monsanto’s Roundup
herbicide. Glyphosate was used in the Farm Scale Evaluations of sugar beet.7
Is something wrong with GM food?
-------------------------------------------------------
Many anecdotes come from farmers in America, telling how their conventional
or organic crops were eaten up by wild animals, while a GM variety growing nearby
remained untouched; or how domestic animals refused GM rations and lost weight
if forced to eat them.8 Given the sensitive instincts that animals often display,
these incidents should be a cause for worry. The government’s advisors
assure us that GM foods are safe - but at the same time some of them advise
that, if GM crops are produced here, the health of the population should be
monitored, especially the health of vulnerable groups like young children.9 This
advice should be heeded. ‘Research in animal feeding trials has indicated
that health effects often only reveal themselves over long time spans, sometimes
even over successive generations.10’
Consumers reject GM foods
--------------------------------------------
A few years ago, supermarkets yielded to public pressure and eliminated GM foods
at least from their own brands. Increasingly, even the indirect consumption
through animal products, resulting from giving GM feed to animals, is being
reversed at the behest of consumers. In last summer’s public debate, 86%
of respondents said they were unhappy with the idea of eating GM food and only
2% were happy to eat GM food in all circumstances. Moreover, 93% said that too
little is known about the effects of GM foods on health. Some regions in Europe
and at least 10 in the United Kingdom have already made it clear that they wish
to remain GM-free.
The verdict
------------------
If GM crops are approved by Ministers, consumers will be losers.
Farmers
The current GM crops were designed to appeal to farmers
--------------------------------------------------------------------------------------------
Most GM crops available today have been designed either to withstand the seed
company’s own-brand herbicide or to produce a toxin within the plant that
will make it a self-contained pesticide. Thus it is farmers who stand to benefit
from this technology. By reducing the destruction of crops by weeds and pests,
the net yields of the crops should be greater. In practice, yields are often
less and much more herbicide is used. Another problem with GM crops is that
weeds with resistance to the herbicide begin to flourish. Resistance to two
or more herbicides occurs simultaneously in some weeds, causing much difficulty
for farmers.
Other problems arise. Roundup has recently been banned in Denmark because
it was contaminating water supplies. Prices of fertilisers will rise as world
supplies of the oil required to manufacture them dwindle. By contrast, there
are a myriad ways in which natural, sustainable solutions have already been
applied to increase crop production, sometimes by as much as two or three times.11
If GM maize is grown, the government has been advised that it be under the
same regime used in the Farm Scale Trials. However, a farmer who obeys this
regulation and applies only a single dose of the herbicide is apt to find his
maize field covered in an unacceptable level of weeds. Non-GM maize farmers
have been using atrazine, which is even more damaging than the weedkiller used
on the GM plants. The use of several applications of this harsh chemical, which
has just banned by the EU, on the non-GM crop is the reason why the GM crop
in the trials proved more friendly to wildlife.
A study of the GM experience in North America, based on the literature and
on interviews with farmers, came to the following conclusion: ‘The evidence
we set out suggests that, in reality, virtually every benefit claimed for GM
crops has not occurred. Instead, farmers are reporting lower yields, continuing
dependency on herbicides and pesticides, loss of access to markets and, critically,
reduced profitability … ‘ 12
GM crops are costly and farmers are liable
-------------------------------------------------------------------
Even when GM crops are successful, the farmer pays dearly for them. They must
pay a special technology fee and must buy the appropriate chemicals. GM seeds
are expensive, and farmers must sign a contract13 that prevents them from saving
seeds for re-planting. The contract also makes them liable to pay damages for
breach of property rights if GM plants are found growing on their land in a
subsequent year, if the license fee has not been paid. It makes no difference
how the plants came to be there. Some American farmers have had to pay crippling
penalties when GM plants grew from seeds that fell to earth in a previous year
or when GM pollen blew in from another farm. Farmers fear such financial losses
and thus continue to grow GM crops. Sometimes they have no choice, because the
large biotechnology companies have caused non-GM seeds to be withdrawn from
the market.
GM crops contaminate other crops
-------------------------------------------------------
Contamination of non-GM crops by GM counterparts is inevitable, as the government
has admitted. GM pollen can travel over large distances. It is distributed by
wind, insects and farm machinery. Organic farmers will be at risk of losing
their certification, as has happened to many in America.
Farmers have responsibility for wild plants and animals
-----------------------------------------------------------------------------------------
Farmers are expected to be custodians of the countryside. With chemical agriculture,
however, wildlife has been in severe decline for several decades The abundance
and diversity of wildlife on organic farms have been demonstrated to be much
greater than on conventional farms. Ironically, the one species that was more
numerous on conventional farms was aphids.14
GM pollen can travel over large distances, carried by the wind, by insects
and on farm machinery. In a recent study of wild turnips in Britain, pollen
from conventional oilseed rape was found 26 km from the pollen donor. This hybridisation
was found to be more widespread and more frequent had been than expected.15 Superweeds
with GM genes, some with resistance to more than one herbicide simultaneously,
have already emerged. They have become a major nuisance in Canada.
Soil organisms and soil fertility are at risk
------------------------------------------------------------------
Although organisms in the soil are out of sight and many are invisible to the
eye, they are nevertheless vital to plants. It is only they that have the capability
of breaking down organic matter so as to become available to feed plants. Little
research has been done so far on the effects of GM plants on the soil, but it
is now known that ‘Pest resistant GM (Bt) crops are exuding pesticides
at unpredicted levels … producing 10-20 times the amount of toxins of
conventional pesticides and leaching toxins into the soil, with negative effects
on insect larvae.’16 A review paper on the effects of GM plants on soil
organisms concluded that ‘The frequency of reports of detectable changes
in soil biota is perhaps somewhat unexpected, given that research into this
area has only recently begun. The long-term implications of these changes in
soil must be assessed.’17 A report by nine experts on soil ecology and related
subjects has warned that GM genes leaking out of crops into soil micro-organisms
and transferred directly (‘horizontally’) into different species
of micro-organisms may result in altered behaviour that could reduce soil fertility.
In the worst case, there could be irreparable, cumulative damage to soil fertility,
with the GM genes spreading uncontrollably over vast areas.18
The verdict
-------------------
If GM crops are approved, some farmers could expect to be lucky in some seasons;
but, on the whole, farmers and the environment, as well, would be losers.
Scientists who do research on GM
If Ministers reject GM crops, scientists who are engaged in developing new
GM plants would find it difficult to secure funding in the United Kingdom for
the development of further GM plants. However, they could re-direct their skills
to genomics applying genetic tests to samples of new plants developed by traditional
breeding methods and not involving the invasion of DNA with foreign genes.
Pure research along the current, invasive lines could be permitted only within
sealed and closely monitored laboratories.
The Government
The Government, while claiming to be neutral, has seen to it that the Minister
for Science and Innovation, Lord Sainsbury, is an ardent supporter of genetic
engineering .19 He undoubtedly retains his financial investments in this sphere,
although these are in a blind trust. He also oversees the Biotechnology and
Biological Sciences Research Council, which awards research grants -- with a
large fraction going for biotechnology. Advisory bodies tend to be weighted
with pro-GM members. Those who urge caution over GM have sometimes felt obliged
to resign or have been threatened. It would be a difficult decision for the
Government to disallow GM crops to be grown here. They would be losers in their
own eyes; but the nation as a whole would win.
GM-seed companies and their shareholders
It is hard to say whether GM companies would be winners of losers if GM crops
were adopted in Britain. The obvious answer would be ‘winner’; but
we already see that consumers have roundly rejected their offerings, GM farmers
elsewhere have lost their markets and farmers in this country are likely to
be cautious about buying the seeds. The Economics Review commissioned by the
Government last summer confirmed that there is now little market for GM crops
An investment company has warned against putting money into this type of fund,
and the companies themselves are already withdrawing some of their enterprises
from Europe.20 Ultimately, the GM companies might do best to cut their losses
and begin producing something their potential customers will actually want.
Conclusion
In conclusion, we should ask why we would want to introduce GM technology
into our food. The introduction and usage of GM technology is being driven not
by any need for such plants but by the eagerness for large profits by powerful
companies. The hazards are tremendous. How could any government hope to cope
with and eradicate life forms that are regenerating themselves throughout the
farms, throughout the countryside and throughout the soils? Will the GM companies
come back and offer us yet more clever technological solutions to counter the
effects? There is so much we do not yet understand about the complex interactions
of the natural world: inside DNA, inside our bodies and amongst all the biological
and physical elements of the environment. Why has Nature herself never performed
the experiment of crossing species? Or has she, and found it to be a failure?
How can Man, who has been manipulating genes for only a few decades, presume
to be more clever than Nature, with 3 billion years of experience? If any of
the foreseen potential hazards become reality, we shall have brought upon ourselves
a just punishment for our arrogance towards the natural world. What unforeseen
consequences lie ahead may be even worse. Once we allow genetic engineering
into this land, it may be impossible to turn back. There is no desperate urgency
to introduce these crops now. But once they are here, it may not be possible
to turn back from the consequences of genetic engineering. Let us be reminded
of the warning of the poet Omar Khayyam21
‘The Moving Finger writes; and
having writ,
Moves on: nor all your Piety nor Wit
Shall lure it back to cancel half a Line,
Nor all your Tears wash out a Word of it.’
