Introduction
by Luke Anderson
Much of the food currently
being eaten in Europe and North America already contains genetically engineered
ingredients. Multinational corporations claim that genetic engineering
is both safe and environmentally sound, but despite high-level political
lobbying and million dollar advertising campaigns, the public opposition
to this technology is growing by the day. Generations that have grown
up with DDT, nuclear energy and BSE have grown suspicious of the premature
assertions of safety churned out by governments pandering to commercial
interests and many independent scientists argue that our current understanding
of genetics simply does not support these overly confident assurances.
In the words of Richard Lewontin, Professor of Genetics at Harvard University:
We have such a miserably poor understanding of how the organism
develops from its DNA that I would be surprised if we dont get one
rude shock after another.
Once released, the
new living organisms made by genetic engineering are able to interact
with other forms of life, reproduce, and transfer their characteristics
to related species. In many cases, they cannot be recalled or contained.
The probability that one or more of these releases could cause serious
ecological harm increases all the time as more and more products are approved.
Companies like Monsanto
argue that these concerns are groundless and claim that: slowing
the acceptance of biotechnology is a luxury the hungry world cannot afford.
The countries of the Third World, however, do not agree. Delegates to
the Food and Agricultural organisation from 18 African countries, for
example, were so outraged that they decided to issue the following statement
to the press: We strongly object that the image of the poor and
hungry from our countries is being used by giant multinational corporations
to push a technology that is neither safe, environmentally friendly, nor
economically beneficial to us. We do not believe that such companies or
gene technologies will help our farmers to produce the food that is needed
in the 21st century. On the contrary, we think it will destroy the diversity,
the local knowledge and the sustainable agricultural systems that our
farmers have developed for millennia and that it will thus undermine our
capacity to feed ourselves.
Some suggest that
the growing opposition to genetic engineering stands in the way of scientific
progress but the nature of progress depends on your point of view.
From my point of view, further threats to biodiversity and human health,
potentially irreversible forms of pollution, expropriation of resources
from Third World countries, increased corporate control of our food chain,
the continued indus-trialisation of our agricultural systems, threats
to animal welfare and the patenting of living organisms do not constitute
progress. Real progress will come about when we learn how to live on this
planet with less arrogance and more care and respect. The work of campaigns
such as Viva! and the growing participation in social justice movements
and actions taken to protect the environment are essential if we are to
move in the right direction.
What is Genetic
Engineering?
According to some
scientists, genetic engineering is a state-of-the-art, revolutionary technology
guaranteed to improve almost every aspect of our lives from health to
the environment to feeding the worlds poorest people. It sounds
too good to be true so why is there such a fuss about it? Campaigners,
critics and many independent scientists claim it is more about feeding
bank balances than feeding the hungry and there are few, if any, benefits
of genetic engineering.
Quite simply, genetic
engineering is the taking of genes from one species to give to another
with the aim of passing on a particular desired characteristic. But the
process is anything but simple as the technology involves tampering with
the very building blocks of life genes. Genetic or hereditary information
is stored in chromosomes which are found in the nucleus of the cells of
each and every living organism. They are made up of a double helical strand
of DNA (deoxy-ribonucleic acid). A gene is a certain segment of DNA which,
when working in conjunction with other genes, brings about the code for
a specific characteristic, for example eye colour or size. Scientists
do not restrict this relocating of genes to similar species but also move
genes between completely unrelated species. The anti-freeze gene from
flounder fish has been inserted into tomatoes, for example, and an insect-killing
gene from bacteria into maize.
Genes are most commonly
inserted into a new host, using one of two methods. Either a virus or
a bacterium is used to smuggle the new gene in or the genes are coated
onto tiny tungsten or gold pellets which are then fired into the cells
of the recipient. Some of the pellets may pass through the nucleus of
a cell and so the new genes will be integrated into the cell's own DNA
(or so the scientists hope). Because of the low success rate in transferring
genes, a marker gene is used to see which DNA has actually
been transferred.
A promoter
is also inserted along with the gene which acts as a switch to activate
the gene in its new host. There are problems, however, with promoters
in that they can force genes to express their characteristics at very
high levels. For example, the promoter may stimulate a plant to produce
high levels of a substance which at low levels remain harmless but which
can have toxic effects in greater concentrations. 3
The
Claims
The 'benefits' of
genetic engineering are lauded by scientists and biotechnology companies
as the way to a better future. They say it will increase food productivity,
benefit the environment, produce disease-resistant animals and crops,
create medicines for humans and provide organs for human transplantation.
1998 saw the first
genetically engineered "nutraceutical". These are foods which
are grown for medicine as well as nourishment, for example in the US a
potato has been produced and tested that protects against diarrhoea.2
Gene Gabrowski of the Grocery Manufacturers of America believes that the
marketing of these 'smart foods' will be worth $34 billion in five to
ten years.3
Other claims for the
benefits of genetic engineering range from increasing the levels of vitamins
and proteins or lowering the fat content in food or delaying the ripening
of produce to the most altruistic of all claims - the ability to feed
the starving millions. In fact, Dr Kevin Ward of the Commonwealth Scientific
and Industrial Research Organisation writes that genetic engineering "may
hold part of the key to the long-term survival of human civilisation".4
Protecting people's
health, the environment and feeding the world's poorest sound like worthwhile
aims and while few people would dismiss these goals, the means to them
as well as the driving forces behind them must be questioned. Besides
it is highly doubtful whether genetic engineering could accomplish these
things or whether the intentions are there to do so.
Selective
Breeding
Depending on who they
are talking to, biotechnology companies will either say that genetic engineering
is state-of-the-art, space-age technology (particularly if they are speaking
to an audience of potential investors) or they will attempt to reassure
a sceptical audience by saying that genetic engineering is merely an extension
of selective breeding which is itself merely an extension of natural selection.
But genetic engineering is not natural, in fact it defies the laws of
nature. Genetic material from one species of plant, bacteria, virus or
animal can be inserted into another species with which they never would
or could naturally breed. Even millions of years of natural evolution
would not produce the genetically engineered examples that are now being
created.
Genetic engineering
is about as far away from natural selection as it is possible to be. The
laws of nature regulate which species and which individuals within a species
will survive and which will not. In nature changes are slow to occur and
are of limited scope. Genetic engineers, on the other hand, are limited
only by their imaginations and the unnatural frequently occurs.
And it's not as if
selective breeding has been a utopian science either - just take a look
at today's farm animals and you will see plenty of horror stories brought
about by selective breeding.
Broiler chickens now
reach slaughter weight in just 42 days, twice as quickly as they did 30
years ago.5 As a result their hearts and lungs cannot cope and even during
their brief lifetime fatal heart attacks are not uncommon. Others will
suffer lameness and broken bones as their legs collapse beneath their
ballooning weight. Birds that are spared slaughter are rarely able to
live much longer. Turkeys have experienced similar problems. Their new
'improved' shape may have provided more breast meat but it has made reproduction
all but impossible and they must now rely on artificial insemination.
Pigs have been bred to gain more weight more quickly and now suffer hip
and joint problems as well as lung and heart conditions. Belgian Blue
cattle must give birth by caesarean section as they have been given a
double-muscling gene which increases the size of the calf but reduces
the size of the pelvic canal.6 Dairy cows produce ten times more milk
than their calves could ever drink and now suffer nutrient deficiencies,
lameness and mastitis as a result.7
Scientists claim that
genetic engineering is far superior to selective breeding because it allows
the desired characteristic to be separated from the undesirable ones and
it allows the transfer of characteristics between species. This makes
the science more accurate, we are told and one day customers will be able
to order their animals to exact specifications. Currently, however, genetic
engineering is at best a hit-and-miss affair.
Genetically
Engineered Animals
As if the selective
breeding scenario wasn't bad enough, genetic engineers are manipulating
animals further than ever before in an attempt to recoup the billions
of dollars that has been invested in research. Genetic engineering is
not a simple process and with every step more pain is inflicted on the
animals involved. Firstly the female 'donor' has a course of injections
to maximise ovulation and is then artificially inseminated. The embryo
is surgically removed, injected with the new gene and then surgically
implanted into another female, known as the 'recipient'. This female may
only survive a matter of days as she will be killed when the embryo is
removed and checked. If all is going well, the embryo will then be implanted
into a surrogate mother who will carry the foetus to full term and give
birth to a transgenic infant, often by caesarean section. Because of the
low success rate, it is estimated that 40 sheep are needed to produce
one transgenic sheep, and even then there is no guarantee that the off-spring
will possess the desired characteristics.
The three main arguments
for genetically engineering animals are for food, xenotransplantation
and medicine.
Food
Genetically engineering
animals for food is all about boosting productivity even further or producing
a product that is 'healthier' for human consumption. An example of this
is producing pigs who have a very small layer of fat, giving a leaner
cut of meat. With animals already pushed to their biological limits on
farms, genetic engineering can only worsen an already appalling situation.
And it's not as if we even need more meat or dairy products. In fact the
British Medical Association recommends we reduce significantly the animal
products we eat.8
Bovine
Somatotropin
The most incredible
story is that of the growth hormone bovine somatotropin (BST), marketed
by Monsanto under the brand name Posilac. Cows injected with it on a daily
basis are expected to increase their milk yield by 10 -20% with no extra
feeding of the cow required. Ironically both the EU and the US produce
a surplus of milk and there is no call for more. In fact, the EU has to
pay excess costs, not just for storage but for subsidies paid to farmers
to reduce their yield! And since the 1950s the United States Federal Government
has had to buy the surplus each year to prevent the price of milk from
plummeting.9 But because over US$1 billion was spent on developing BST,
it must be promoted and profits shown. For the dairy cow the price paid
is very dear.
BST is a genetically
engineered copy of a naturally-occurring cattle hormone. But the side
effects are so severe that the EU introduced a moratorium on the drug
until 2000 and it is banned in Canada and a number of other countries,
despite efforts of Monsanto to prise open those markets. The sale of Posilac
in the US is thought to generate an annual income of between $300 and
$500 million.10
Normally for about
12 weeks after a cow gives birth she lactates but at the expense of her
health. She will lose weight, become infertile and more susceptible to
diseases. When output diminishes her body recovers gradually. So by injecting
BST the farmer not only increases milk output but postpones her recovery
for another 8 -12 weeks thus rendering her more susceptible to disease
including mastitis, an udder infection exacerbated by over-full udders.
At any time, one third of the EU's dairy cows are suffering from mastitis.11
Not only is this extremely uncomfortable for the cow, but it means an
increased use of antibiotics, residues of which are found along with an
increased amount of pus in the milk.
Even during the experimental
stages of the drug, problems were obvious. In1990 data was leaked about
the significantly increased rates of udder infection in cows that had
been injected with Monsanto's hormone as well as an unusual incidence
of severe birth defects in the offspring of the hormone-treated cows.12
A review then showed high incidences of foot and leg injuries, metabolic
and reproductive difficulties such as retained placenta, a decrease in
birth weight and uterine infections.13 Despite this the hormone was approved
for sale in America in 1994. Mark Kastel from the Wisconsin Farmers Union
found widespread reports of spontaneous deaths amongst the treated cows,
calving problems and an inability to wean cows off the drug. All in all
Monsanto has admitted to 21 possible side-effects of Posilac.14
In the US hundreds
of farmers called the National Farmers Union (NFU) hotline reporting problems
associated with the hormone when it was first on sale and by 1995 the
NFU reported that in some areas of the country 60 -90% of farmers have
tried a bovine growth hormone and discontinued its use.15
Should
We Be Drinking More Milk Anyway?
No! Nutritionist Dr.
Gill Langley sums up the reasons:
"Cow's milk
is a common but still unrecognised cause of allergy in infants and children,
and symptoms range from diarrhoea and vomiting to eczema, asthma and chronic
sleeplessness. Infants under one year who are given cow's milk as the
sole or major food may develop iron deficiency, not only because it is
a relatively poor source of iron but also because it can cause iron loss
through gastrointestinal bleeding. Lactose intolerance is a significant
cause of repeated abdominal pain in children. Milk and other dairy products
account for about one third of the saturated fat intake and saturated
fat is a risk factor for heart disease. Some studies have directly implicated
cow's milk consumption in heart disease and an insulin-dependent diabetes.
Other problems have also been associated with dairy milk"16
With soya milk, cheese,
yoghurts and cream freely available in every high street, avoiding the
dairy has never been easier. It is perfectly clear that milk is not needed
in a healthy diet but Dr Kevin Ward sees things differently. If the milk
is not good for us, he reasons, we'll change the milk. "It may be
possible", he writes "to manipulate the composition of milk
to improve its nutritive value for human consumption, for example, by
making the protein component more homologous to human milk by altering
the lipid (fat) or carbohydrate profile."17 If you have to do all
this to make a foodstuff palatable, digestible and healthy then doesn't
that tell you something? Does it not suggest that cow's milk is not good
for human health and that it is not natural to drink it?
Disease-resistant
Animals
It is claimed that
productivity of meat, milk and eggs can be even further enhanced by genetically
engineering disease-resistant farm animals. This would reduce the amount
of antibiotics used and so allegedly benefit the consumer. But genetically
manipulating an animal could have disastrous consequences for the animals
as well as the people who consume the flesh of that animal because long-term
effects cannot be predicted.
Clinical microbiologist,
Professor Richard Lacey is extremely concerned about the effects of genetically
altering farm animals. Although it is not possible to make animals resistant
to all diseases, he claims, they could certainly be made resistant to
some. However, we do not know the effect that these modifications will
have on the animal and its health. Besides, disease is an inevitable consequence
of life due to environment, diet and overcrowding and so will never be
completely eradicated. Even if certain diseases are banished, others will
appear and this is where the problems lie. "We cannot cope with the
consequences".18
Xenotransplantation
Xenotransplantation
is the transplanting of organs from another species into humans. The Cambridge-based
biotech company, Imutran produces pigs with human genes to overcome the
immune reaction when the organs are transplanted and so prevent the rejection
of the new organ. They recently revealed plans to use genetically modified
pigs' livers as a temporary dialysis machine for patients awaiting a human
organ. The Home Office refused to permit the use of organs from chimpanzees,
gorillas and orang utans.19
Again, the main concerns
centre on animal welfare and rights and human health, particularly with
the possibility of transmitting a pig virus known as porcine endogenous
retrovirus (PERV) to humans. Studies to date have offered conflicting
conclusions. Dr Ulrich Martin from Germany found that PERV can be produced
by cells in pigs' aortas, livers, lungs and skin. All of these are used
for transplants and the researchers concluded that there was " a
serious risk of retrovirus after xenotransplantation". A second study
at the US Centers for Disease Control and Prevention found no evidence
of PERV infection in 10 transplant patients who had received implants
from pigs, despite receiving a large number of pigs cells and being treated
with drugs that should have reduced their ability to resist PERV infection.20
It seems nothing is
certain yet the medical industry as well as the food industry, seems content
to utilise this technology, even if it is at the cost of human health.
Other
Medical
The other major medical
development is the production of sheep and cows who secrete useful drugs
in their milk. For example, in 1990, the Roslin Institute produced 'Tracy',
the transgenic sheep that secreted large quantities of the human protein
alpha-antitrypsin.21 This protein is secreted mainly from the liver in
humans and a deficiency of it is linked to emphysema.
Cloning
Once an animal has
been engineered to display the required characteristics, scientists are
able to create more identical animals by cloning them. The nucleus from
one of the animal's cells is transplanted into a fertilised egg from which
the nucleus has been removed. The egg is then cultured in vitro (in the
laboratory) before being implanted in the womb of a surrogate mother.
The surrogate mother is killed in order to ensure the safe delivery of
the cloned off-spring.
In February 1997,
The Roslin Institute announced that it had successfully cloned a sheep,
Dolly. In theory, it won't be long before there are whole herds or flocks
of genetically identical animals. Aside from the inevitable pain that
is caused in the process, the main concern is that the reduced gene pool
which make up the animals may lead to a reduced resistance to disease
and an increased rate of deformities.
It also brings in
to question how far geneticists are prepared to take their science. American
scientist, W French Anderson proposes to conduct gene therapy experiments
on human foetuses which critics claim is the slippery slope to 'designer
babies'.22 American scientist, Dr Richard Seed has promised that he will
have cloned a human by the year 2001 and if US law prevents it, he says
he will go to Mexico. It seems there are no limits at all but in the UK
and the US, human cloning is illegal at present.
Genetically
Engineered Crops
This is a subject
which has united the majority of consumers world-wide. With the appearance
of genetically modified foods on our supermarket shelves it seems the
experiment began long before the consumers really had time to think about
the issues at stake.
On September 1st 1998
it became a legal requirement in the UK to label protein from genetically
modified soya and maize although there is no legislation covering soya
lecithin and soya oil. The reason given by the Department of Health for
this apparent loop-hole is that these ingredients are so highly refined
that they are no longer deemed to be genetically modified. Since more
than 60% of processed foods contain soya and these derivatives account
for 90% of soya products, this decision may mean that the majority of
processed foods in the shops will contain genetically modified derivatives.23
With the foods already
appearing on our shelves the debate over their safety rages on. The government,
backed by the multinational biotech companies, are doing their utmost
to convince us that these crops are safe but consumers have heard it all
before. Just as the House of Commons only served beef from a guaranteed
non-BSE stock in the Highlands, so our ministers are enjoying only food
that is free from being genetically tampered with.24 You would think if
our MPs were so convinced of the safety of these foods, they would be
keen to prove the point and lead by example.
But many feel the
government are deceiving us. Environment minister, Michael Meacher tried
to calm an ever-growing opposition to these crops by promising that no
herbicide-resistant crops would be grown commercially in the UK before
autumn 1999, just one year from when the promise was made. From 1999,
six farms are allowed to grow the crops on a commercial basis to establish
the effects of widescale planting. (Until 1998 only small scale trials
were permitted.) But the UK couldn't have grown these crops within a year
anyway due to a row in Europe over their safety so Meacher's promise was
meaningless.23 Interestingly, despite the French calling a moratorium
on oilseed rape, Britain's agricultural minister Jeff Rooker claimed that
the UK was not in a position to do the same as it would contravene EU
law.26
Meacher also promised
to ban the commercial growing of insect-resistant crops until 2001. By
some coincidence, the testing guidelines would not allow crops to be commercialised
within that time frame anyway (except for one strain of maize which could
not be grown in the UK) so it seems the public were given yet another
empty promise from Meacher.27
The cynical could
be forgiven for thinking that the government is hoping to ride the storm
and gently ease consumers into accepting these crops. They have agreed
to 50 test sites by the year 2000 which obviously means more genetically
engineered crops not less. Most worryingly, the effects will be monitored
by biotech industry.28
So
What Is Wrong With Genetically Engineered Foods?
Concerns can roughly
be broken down into five arguments: animal welfare, health, environment,
a sustainable future and moral.
Animal
Welfare
Animals must already
endure constant misery and pain on farms and by increasing their productivity
we could be pushing these creatures beyond their limits. We have already
looked at the legacy of selective breeding which has left us with animals
unable to carry out their natural functions and in some instances have
meant a lifetimes worth of pain. But with genetic engineering, the situation
has worsened.
The many failures
of genetic engineering read like something out of a horror novel. Pigs
born with a human growth hormone were arthritic, ulcerous, partially blind
and impotent.29 Others given the bovine (cow) growth hormone were grossly
deformed and at just two years old were crippled with arthritis. Despite
this they could still breed and their meat was highly desirable being
low in fat, so low in fact, that they were in danger of dying from the
cold.30 Pigs given a human growth hormone suffered agonising arthritis
and were able only to crawl around on their knees.31 Lambs have suffered
similarly. In America, transgenic lambs developed a lethal form of diabetes
which led to liver, kidney and heart disorders. All the lambs died of
their diseases before they were 12 months old.32 Even transgenic chickens,
implanted with the bovine growth hormone have been developed. Given the
crippling effects and diseases already brought about by selective breeding,
the future for chickens doesn't look bright. In 1980 the steroid hormone
diethylstilboestrol was given to calves in Italy with disastrous effects.
It contaminated baby food causing cancer in infants and brought about
the development of secondary sexual characteristics such as menstruation
and breast development in young children.33
We should also remember
that because the majority of the world's crops are fed to farm animals,
they are ingesting genetically modified crops on a regular basis. Who
knows what sort of detrimental effects this will have on them and their
off-spring?
As for the animals
who are unfortunate enough to be selected for the genetic engineering
tests, untold horrors await them. We may never see the 'accidents', or
'mistakes' but the biotech companies certainly shout loudly about their
'successes'. Dolly is the infamous sheep, cloned at the Roslin Institute,
whose picture has appeared in every paper but we have never seen what
happened to the hundreds, maybe thousands of sheep that were tested on,
mutilated and died in order for the world to see the one 'success'. Even
then the truth about Dolly wasn't widely reported. In 1998 a Norwegian
newspaper carried the story that Dolly was "eating herself to death".
Despite being twice the size of her litter mates, the newspaper reported
that Dolly couldn't stop eating.34 So much for success.
Health
The simple fact is
that we don't know enough about this science or its long-term effects
to say for certain what genetic engineering will do to our health. A gene
does not work in isolation and scientists do not understand the way in
which new genes interact with every other gene in the sequence.
Potential hazards
include new toxins and allergens in food and more virulent diseases in
the crops which could lead to health problems. With genetic engineering
we are ingesting genes that have never before been a part of the human
diet - genes from certain bacteria, rats or scorpions may affect humans
adversely but there is no way of knowing until it is too late. Besides,
vegetarians and vegans have made a choice to cut out animal products from
their diet for very good reasons - we certainly don't want to get to a
stage where we don't even know if our vegetables are vegetarian.
Yet again the messages
are mixed. The government promises there is nothing to worry about but
they said the same about beef. The supermarkets are willing to stock these
foods but reading between the lines they are not so sure either. For example,
Sainsbury's, produced a leaflet entitled, Genetically Modified Soya which
guarantees that no baby foods are made with genetically modified products.
Why try to reassure us with this fact if they do not have concerns for
health? And if there are concerns for health, why do they allow any genetically
modified products in their store? It doesn't make sense.
Councils all over
the country have ordered suppliers of school meals to shun genetically
modified foods. Stockport council in Cheshire banned them from 120 schools
because of health concerns and is also planning to ban them from staff
canteens and meals on wheels. Gardiner Merchant who provide school dinners
for a large number of Local Education Authorities have instituted a 'no
genetically modified organism' (GMO) policy into their own guidelines.35
And the fears are
not without substance. Scientific studies have linked bovine growth hormone
(rBGH) to cancer. rBGH stimulates the production of another growth hormone
called Insulin-Like Growth Factor1, a naturally occurring hormone-protein
in cows and humans. rBGH increases the levels of IGF-1 in the cow's milk.
Because this is active in humans, causing cells to divide, some scientists
believe that ingesting high levels of it could lead to uncontrolled cell
division - cancer. This has been backed up by several scientific studies
in the UK and the USA. Professor Samuel Epstein from the University of
Illinois found that IGF-1 from rBGH- treated cows may lead to breast and
colon cancer in human milk drinkers.36 An American study in May 1998 found
a seven-fold increased risk of breast cancer amongst pre-menopausal women
with high levels of IGF-1 in their blood. A separate study in January
1998 found a 4-fold increased risk of prostate cancer among men.37 This
is the strongest known risk factor, even exceeding that of family history.
Prostate cancer is the most common form of cancer in non-smoking men.
In the USA since 1995,
rBGH-produced milk need not be labelled so consumers are not even given
the right to choose. This policy was decided by Michael R Taylor of the
Food and Drugs Administration who previously was a partner in a law firm
that represented Monsanto and now works for... Monsanto!38 In fact, the
biotech firm has been known to take legal action against farmers who label
their milk 'BGH-free' although in the face of public opposition they have
given up his tactic.39
Monsanto's Roundup
is the world's biggest selling herbicide and the company has used genetic
engineering to dramatically increase its sales. Because using too much
of the herbicide destroys the crop as well as the unwanted weeds, Monsanto
genetically created crops that were resistant to this particular herbicide.
Farmers can now use far greater amounts of the herbicide without fear
that it will damage their plants and Monsanto can amass even greater wealth.
However, Roundup has been shown to cause severe health problems, stemming
primarily, it is thought, from unlabelled inert ingredients designed to
make it easier to use and more efficient. Roundup consists of 99.04% "inert"
ingredients including polyethoxylated tallowamine surfactant (POEA) which
has been discovered by Japanese researchers to cause acute toxicity in
patients. Symptoms include gastrointestinal pain, vomiting, excess fluid
in the lungs, pneumonia, clouding of consciousness and destruction of
blood cells. Another Roundup "inert" isopropylamine is extremely
destructive to the mucus membrane tissue and upper respiratory tract.40
There is further evidence to suggest that transgenic soya sprayed with
Roundup may contain increased levels of plant oestrogen which mimics female
hormones and there are concerns that this could affect human reproductive
systems.41 In 1994, Roundup was used on almost 800,000 acres in the UK.42
Testing these ingredients
on humans doesn't seem to matter to the companies involved. No tests on
humans were carried out at all before the soya that goes into Batchelor's
Beanfeast was approved43 and it is this lackadaisical approach to the
public's health which has angered many people. But even when tests are
carried out, their findings are ignored if they do not suit the manufacturers.
When the Rowett Institute found that feeding rats genetically modified
foods stunted their growth and suppressed their immune system, the government
still refused to ban it.44 This decision would suggest that they consider
animal testing pointless in which case they should end all vivisection
immediately. But if they do believe it to be valid, they should take on
board the outcome of these experiments and ban genetically engineered
foods. They can't have it both ways.
According to The Daily
Mail45, a huge experiment into the health consequences of genetically
engineered foods is planned with consumers as the guinea pigs. Government
health experts have asked supermarkets to hand over their loyalty cards
so they can monitor who is buying GM foods and they will cross-reference
this with registers for cancer, birth defects and hospital admissions.
Conducting tests after these foods have been released could mean lives
are lost or ruined because the government wouldn't show caution but rather
chose to rush in blindly. The sorry truth is the only way they will ever
know the harm genetically modified foods can do is when it is too late
and the harm has been done.
Environment
At a time when an
estimated 50,000 species are becoming extinct every year any further interference
with delicate ecosystems could spell disaster.46 Unlike synthetic pollutants
genetically engineered organisms cannot be recalled as they are alive
and can reproduce, mutate and cross-breed. Once released into a complex
environment the outcomes become increasingly unpredictable due to cross-pollination
with related species causing new life forms. This is known as geneflow.
The biotech companies
claim that genetically engineered crops will benefit the environment by
reducing the use of herbicides but this is not so. Glyphosphate herbicides,
like Roundup accounts for one sixth of Monsanto's total annual sales and
are worth $1,200 million per year.47 There is no incentive for them to
reduce the use of herbicides and by genetically engineering crops that
are resistant to them, Monsanto can produce and sell even more. This could
mean environmental destruction on a huge scale.
Once sprayed, Roundup
is absorbed into soil components and remains active. Residues have been
found in lettuces, carrots and barley planted one year after the glyphosphate
treatment. Not only can it harm human health, it kills beneficial insects
such as lacewing, ladybirds and parasitoid wasps, affects earthworms and
beneficial fungi and increases the susceptibility of crop plants to disease.48
What's more, by removing
all the weeds, soil composition is destroyed leading to soil erosion.
If weeds become resistant to these herbicides (and eventually it is predicted
they will) this will lead to increased doses, stronger chemicals and even
more sales - all good for Monsanto.
Pesticide-producing
plants are also being developed which is predicted to lead to the appearance
of resistant insects and of course the pesticide is not selective, killing
beneficial insects too. In one test, inserting a gene from a snowdrop
into a potato made the potato resistant to greenfly but also killed the
ladybirds feeding on the greenfly.49 Lacewings who prey on the corn borer
and are food for birds died when they consumed pests raised on Novartis's
genetically modified maize.50
As if the threat from
these pesticides and herbicides wasn't enough, we have the possibility
of 'superweeds' being created. In September 1998, the Daily Express reported
that scientists at the University of Chicago created a superweed by accident.
They were trying to create transgenic crops that allowed farmers to spray
expensive herbicides just once before harvesting, but in one common weed
(thale cress) it caused a massive fertility boost. This dramatically increased
the likelihood that it could cross-pollinate with related species, creating
uncontrollable weeds. This not only leads to competition with native plants
but farmers will require more and stronger herbicides in order to control
them. A vicious circle can be visualised where biotech and agricultural
companies are the only winners.
Natural species could
be driven out by these superweeds with a knock-on effect for all the species
dependent on them for survival. It only takes one mistake for huge and
permanent disastrous effects to take place. English Heritage has warned
of the widespread destruction to native birds and insects and the creation
of aggressive weeds and even Prince Charles has spoken out in favour of
the environment.
It is not as if Monsanto
has an unblemished record when it comes to environmentalism. According
to The Ecologist 51, they have caused massive environmental pollution
through production of enough PCBs to kill all mammal life in the world's
seas. And in 1995 Monsanto ranked fifth among the US corporations in the
Environmental Protection Agency's Toxic Release Inventory having discharged
37 million pounds of toxic chemicals into the air, land, water and underground.52
Genetically modified
crops have been released at over 300 test field sites in Britain and despite
safety regulations some have started to 'escape' already. We will only
know the impact these have on the environment when it is too late to protect
it.
Sustainable
Future
Monsanto boasts that
biotechnological advances will triple the world's food crop without needing
any more farmland thus saving rainforests and the world's precious habitats.
But one of the most important practices to promote a sustainable agriculture
in developing countries is to save and selectively cross-breed seeds from
year to year. Monsanto has undermined this practice by forcing any farmer
who buys their patented Roundup Ready seed to sign a contract saying they
will not use any of the harvested crop as seeds for next year.
And it gets worse
- the American Delta and Pine Land Company patented the Technology Protection
System (TPS), known to the rest of the world as Terminator Technology.
This system ensures that plants will produce self-terminating off-spring
and that farmers will have no choice but to buy new seeds every year.
According to the Delta and Pine Land Company the primary sales targets
are "Second and Third World countries".53 So much for the their
commitment to ending world hunger. Just two months after being patented,
Monsanto bought the company. If the joint venture between Monsanto and
Cargill (who virtually have the monopoly on seed sales in the developing
world) succeeds farmers will have no choice but to buy these self-terminating
seeds every year.54 Poverty can only increase, small farmers will go out
of business and global food production could eventually end up in the
hands of just a few multinational corporations. Recognising the situation,
the Agriculture Minister in India banned any introduction of these terminator
seeds in to the country.55
Terminator technology
is predicted to become an agent in biological warfare in the future. Theoretically
it is possible for specific traits to be switched on and off, thus allowing
direct control of a nation's food supply and economy. It seems the military
and security forces are particularly interested.56
Hand in hand with
these patented Roundup Ready seeds go their corresponding weedkiller,
Roundup, designed to kill everything except for the specific crop. But
what constitute weeds for Monsanto are food, fodder and medicines for
the Third World. In West Bengal, for example, 124 "weeds" collected
from rice fields have economic importance for farmers and all these would
be lost if farmers were to sign up to the biotech company's schemes.57
Monsanto's promotional
literature is steeped in myths about world hunger. The truth is there
are no global food shortages. The problem lies with producing the wrong
food - fodder for the West's farm animals instead of food to feed the
world's people. There are over one billion cows alive today, grazing on
six continents 58 and the amount of feeding they require is phenomenal.
Simply grazing them isn't enough so it is substituted with grain, oil
seeds, soya, fish meal and until recently in the UK with other ground
up animals. The West cannot produce enough feed for their animals and
so 90 per cent of the concentrates used for animal feed in Britain comes
from the developing world who grow and sell crops to pay off debts to
rich western countries like Britain and America. Approximately 40 million
tonnes of food would eliminate the most extreme cases of hunger around
the world and yet the developed world feeds 540 million tonnes of grain
to farm animals every year.59
It is estimated that
800 million people go hungry each day60 and this number is increasing
even though food production has increased per capita since 1970.61 Global
access to food is now solely by purchase so boosting food growth doesn't
help people who cannot afford to buy it. Peasants in the developing countries
have lost land, independence, tradition and community as well as food.
For them the price is very dear.
The leaders from some
of the poorest countries see the truth plainly. Delegates from 24 African
countries at the 1998 Food and Agriculture Organisation were so incensed
at Monsanto's advertising they released a joint statement objecting to
Monsanto's image of the poor and hungry from their countries being used
to promote a technology that is neither safe, environmentally friendly
or of benefit to them.62
Traditional farming
methods work and have done for centuries. According to Greenpeace 63,
in Latin America soil conservation and organic fertilisation programmes
tripled or quadrupled yields within a year. Indigenous crops are suited
to the soil type and have adapted to that environment over hundreds of
years. These sort of education programs are the best way to keep small
farmers producing foods to feed their community.
And in the West, the
best contribution we can make to preventing world hunger is to switch
to a vegan diet. (See guide 12, Food For a Future.) The majority of the
crops grown in poorer countries are exported to the West in order to feed
our farm animals so we can enjoy the luxury of meat and milk, a luxury
which is harming our health anyway. If we didn't have so many farm animals,
not only would we be able to save rainforests and the world's precious
habitats but we would be able to help the poorest people by allowing them
the freedom to grow crops that they themselves need.
Moral
The moral argument
challenges genetic engineering on a physical as well as a metaphysical
level. On the physical level, we can clearly see what we are doing to
the animals and we can predict some of the damage that may be done to
our physical world. Critics question whether we have the right to inflict
this pain and suffering on sentient beings or to bring about such radical
and permanent changes in the world around us. They ask if it is acceptable
to inject hormones daily into a cow with the effect of causing her permanent
discomfort in order to produce a product no one needs. Or if it is morally
acceptable to perform agonisingly painful experiments on hundreds of pigs
and then kill them in order to produce one animal that gains weight quickly,
thus preparing the way for thousands, perhaps millions more animals to
be in pain. Or if it is acceptable to introduce genes from one species
into another and so contaminate the food on our shelves.
These are questions
that ordinary people are asking themselves and the answer is coming back
loud and clear from all around the world: no, we do not have the right.
On a metaphysical
level it is argued that we are playing with the foundations - the very
building blocks - of life. The Prince of Wales has spoken out on this
point: "I happen to believe that this kind of genetic modification
takes mankind into the realms that belong to God, and God alone."
Should human beings be tampering with the genes that constitute life as
we know it and altering that life forever? It is a big question and one
that deserves plenty of attention and debate.
Ethical Committees
have been set up to discuss these very issues, but according to Dr Mae-Wan
Ho of the Open University, they generally limit themselves to more trivial
questions, such as whether inserting a pork gene into a tomato runs counter
to religious beliefs, and avoid the one big question - should we be doing
this at all?64
Friends
in High Places
Monsanto is one of
five companies who spearheaded Bill Clinton's 'welfare to work' campaign
in America, donating considerable sums of money to the government. Cynics
may ask if this had something to do with why Clinton phoned Tony Blair
in the summer of 1998, pressuring him to continue producing genetically
engineered foods.65 Surely Britain's policies regarding our own foods
does not come under his remit, but he wasn't just tackling the UK.
Leaked Cabinet documents
from New Zealand showed that the US government threatened to pull out
of a potential free trade agreement with New Zealand if they were to label
and test genetically modified foods. US government trade representatives
were also sent over to 'discuss' the issue with Japan who insisted on
labelling genetically modified products.66
In December 1997 the
US Department of Agriculture attempted to redefine the term 'organic'
to include genetically engineered crops and those contaminated with nuclear
irradiation and toxic sludge! They also proposed banning attempts to create
food standards higher than their own! 99% of the 220,000 comments received
denounced the proposal.67
In the UK, the ranks
are tight too. The Advisory Committee on Novel Foods and Processes (ACNFP)
is supposed to be made up of independent academics whose job it is to
advise the government but Greenpeace research has shown that its members
often have very close links to the industry. A second advisory committee
dealing with genetically engineered crops contains representatives from
Zeneca and PPL Therapeutics (the firm that cloned Dolly).68
In June 1998, The
Observer reported that Lord de Ramsey, head of the Environment Agency
who aims to "encourage the conservation of natural resources, animals
and plants" was being paid by Monsanto to grow genetically engineered
crops on his land.
When people from within
the industry try to speak out they are silenced. In August 1998, Professor
Arpad Puszati was forced to retire early from the Rowett Institute when
he revealed that rats fed on modified potatoes were poisoned. Professor
Philip James who runs the Rowett Institute advises Tony Blair on food
safety and has major links with companies at the forefront of genetically
modified foods.69
It is not surprising
that the government is only fed positive news regarding this technology.
Large corporations fund the majority of research and withdraw the funding
if the results are not what they want to hear. For example, UK approval
of genetically altered soya was based solely on safety data collected
by Monsanto who produce the product.
The
Opposition
Right across the world,
people are taking a stand against genetic engineering, from governments
to farmers to grass-root activists. The Austrian & Luxembourg governments
have banned the growing of genetically engineered maize because it has
a built-in insecticide which can harm beneficial insects and antibiotic
resistance- makers which can be transferred down the food chain to meat.
France imposed a two year moratorium on oil seed rape and sugar beet because
of the risk of the herbicide being transferred to weed relatives and Greece
has banned oilseed rape for the same reason.
In Sweden, the main
farmers' organisation LRF has demanded that animal feed producers declare
themselves GMO free.70 In Switzerland concerned farmers joined food producers,
consumers and Greenpeace in a legal challenge to the government's approval
of genetically engineered soya.71
Independent scientists
are also queuing up to denounce genetically modified foods. Professor
E. Ann Clark, Associate Professor Crop Science at the University of Guelph,
Ontario believes: "It is not a matter of 'if' but 'when' these inserted
genes will get out into the wider [plant] community... the only question
is whether we ourselves (the creators of the genetically engineered organisms)
will have to face the music, or whether it will be our children, or their
children."72
And Dr Mae-Wan Ho,
a most out-spoken critic of genetic engineering warns: "The large
scale release of transgenic organisms could be worse than nuclear weapons
as a means of mass destruction."73
A statement issued
by 21 scientists from seven countries including Professor Richard Lacey,
Department of Microbiology at Leeds University; Professor Brian Goodwin,
Biology Department at the Open University and Professor Jacqueline McGlade
from the Department of Biological Sciences at the University of Warwick
reads: "It is disturbing that the already considerable and substantial
scientific literature on safety and ecological aspects of genetic engineering
has not found corresponding responses in the safety policies and programmes
of governments or the industry.... With genetic engineering familiar foods
coud become metabolically dangerous or even toxic."74
The public agree.
In October 1998 a Friends of the Earth poll showed 78% of consumers didn't
favour genetically modified products even being on sale and 58% were actively
opposed to their presence.75 In June of the same year, a poll commissioned
by The Guardian and ICM found that 95% of people wanted foods derived
from genetically modified crops to be labelled.76
But only lack of sales
will influence the companies, manufacturers, governments and farmers and
consumers are voting with their wallets. Organic foods have never been
more popular and some companies do seem to be listening to the demands
of their customers. Holland and Barrett, for example have delisted Batchelors
Beanfeast from their shelves and Iceland boss Malcolm Walker has denounced
genetically modified products as "Frankenstein foods".
Others, however, do
not seem to care. In 1997, Unilever's chairman Morris Tabaskblat promised
that if consumers in one country didn't want genetically engineered ingredients
they would remove them, otherwise they would not be doing their job properly.
But Unilever broke their own promise, saying they cannot find enough non-genetically
altered soya for their products. International soya traders Norgrow UK
say this is "incorrect".77
Grass roots activists
are making their views known world-wide. In India, for example ten million
farmers in the southern state of Karnatake launched their 'Cremate Monsanto'
campaign in protest at the biotech giants' presence in India. On November
28th 1998 Indian farmers burnt a field trial of Monsanto's genetically
manipulated cotton. Since then other fields have been burned and crops
damaged world-wide by protesters.78
The California Croppers
is an American football team made up of activists who hold their matches
in genetically modified crop fields and in the US and the UK activists
have taken to throwing vegan pies at biotech bosses such as Monsanto's
Robert Shapiro and Novartis's Douglas G Watson.79
All around the world
people are campaigning for an end to genetic engineering and the effect
of these campaigns has been amazing. A report leaked to Greenpeace, written
for Monsanto by a former polling advisor to Clinton, Blair and Mandela
reveals: "an on-going collapse of public support for biotechnology
and GM foods. At each point in this project, we keep thinking that we
have reached the low point and that public thinking will stabilise but
apparently we have not reached that point."80
What
Can I Do?
Join Viva! to campaign
for a more sustainable future where animals, the environment and the world's
poor are shown the compassion they deserve.
Remember that consumers
wield considerable power so read food labels carefully, educate yourself
and choose wisely. Lobby MPs, supermarkets and food companies and make
a point of buying from companies who confirm they do not use any genetically
modified produce. This is a list of current supermarket policies (but
things change fast so keep an eye on your local supermarket).
- Iceland has removed
GMOs (genetically modified organisms) from its own brands and other
products that contain GM derivatives are gradually being labelled.
- Tesco is also gradually
labelling foods containing soya oil or lecithin as having GMOs unless
the original soya was certified GMO free. They have also banned the
use of GM maize by farmers producing especially for them.
- Safeway's leaflet
on the subject suggests environmental benefits of genetic engineering
and they do stock GM tomato puree.
- Co-operative Wholesale
Society won't stock GM tomato puree as there are "no consumer or
environmental benefits". Although they are not banning GMOs from
the 60 brand items that they currently stock, they are working on GMO-free
own brand items.
- Asda is gradually
removing GMOs from all its own brand foods and is also labelling soya
lecithin and oil.
Waitrose currently has only seven own brand items that contain GMOs
and is trying to make them GMO free. They are considering labelling
lecithin and oil.
- Somerfield are
trying to minimise GM soya in their own brands but won't label foods
that contain GM soya lecithin and oil as "there's no legal requirement".
- Sainsbury's pioneered
GM foods with its tomato paste and doesn't label GM soya oil or lecithin.
Lord Sainsbury, former head of the supermarket group, is leading a campaign
with the government to promote GM foods. However, the supermarket says
it is trying to source non GE-soya for its own brands.
- Marks & Spencers
says it will label GMO lecithin but not soya oil and has no plans to
take GMOs out of their own brand goods.81
Write to your MP expressing
your concerns for the animals used in genetic engineering experiments.
If you haven't already, cut out meat, eggs and dairy products from your
diet, or at least insist on organic free-range products. Viva! can provide
information on how to go vegetarian or vegan.
Lobby the caterers
at your child's school and insist that they provide GMO-free food. As
of January 1999, 21 out of 33 London boroughs and at least 14 county councils
had adopted official policies against the inclusion of GM foods or were
actively seeking to avoid them.
