The great divide
Bob Holmes
From New Scientist, 27 February 1999

WE MAY be living in the global village, but
even villagers bound together by language and culture
don't always see eye to eye. In the US, biotech firms
and activists alike are bemused by events unfolding
across the Atlantic. Even the fiercest opponents of
GM crops realise that they cannot hope to mobilise
public opinion as effectively as their British
counterparts.

The main difference between Britain and the US is
the long and terrifying shadow cast by BSE, suggests
Jane Rissler of the Union of Concerned Scientists in
Washington DC, a group which argues that some GM
crops may be environmentally damaging. "It makes
people very sensitive about what government is telling
them and what science is telling them," she says. "I
suspect if we'd had mad cow disease here, we would
probably have more worry."

Philip Angell agrees. He is the director of corporate
communications at the GM food giant Monsanto's
headquarters in St Louis, Missouri. "This kind of
high-visibility, high-intensity reaction on the part of
the British press is a confirmation of how deeply
scarred the British people are by the BSE experience.
It's going to take a long time for that wound to heal."

Another factor behind the transatlantic divide is that
North American consumers expect food to be cheap.
They seem less willing than Europeans to pay a
premium for organic produce, for instance. Tim
Martin of Pioneer Hi-Bred, a seed company in Des
Moines, Iowa, is convinced that Americans would not
pay more for the segregation of non-GM foods.
"Quite often they don't respond the same way at the
counter, when they're paying, as when a survey's
being taken," he says.


In this climate, anti-GM crop activists in the US are
turning to the law rather than trying to inflame public
opinion. Last week, 65 plaintiffs including
Greenpeace, the Sierra Club and the International
Federation of Organic Agricultural Movements filed a
suit in the district court in Washington DC against the
Environmental Protection Agency (EPA), arguing that
it acted unlawfully in approving crops engineered to
produce Bt toxin, an insecticide produced by the soil
bacterium Bacillus thuringiensis. The EPA rejects
this accusation: "Biotech products we review fully
comply with all legal requirements designed to ensure
that they are environmentally sound."

The suit demands that the EPA withdraws approval
of all Bt plants and stops approving any new ones
until it has done a complete assessment of their
environmental impact. The EPA's opponents claim
that beneficial insects may suffer and that genes for
Bt could spread to other species. They argue that Bt
plants will accelerate the evolution of resistance to the
Bt toxin by insect pests, thus depriving organic
farmers of a natural insecticide. The plaintiffs say this
violates a federal law that prohibits the EPA from
approving pesticides with damaging environmental
effects.

This legal battle could take years to resolve. In the
meantime, more Bt and other GM crops will be
planted in the US. The expansion of GM agriculture
in the US will make it harder for consumers
elsewhere to avoid them. "The problem that
Europeans have is that most of the GM foods they
have are coming from the US," says Kalee Kreider of
Greenpeace in Washington DC. No matter how much
public pressure Europe's activists raise, it will do little
to halt the onward march of GM produce as long as
the US continues to back the technology.

How to price what we put on our plate
From New Scientist, 27 February 1999

Debora MacKenzie

FOR most people, the main question about GM
food is: do I have to eat it or not? If we are to have
that choice, GM crops will have to be segregated
from plough to plate and all products containing GM
food labelled as such.

The US government claims that this would impose
heavy costs on its food suppliers. It threatens a trade
war if the European Union responds to public
pressure by demanding segregation of GM crops
within US exports. But a new analysis suggests that
the costs of segregation and labelling are manageable,
and could even enhance trade. "This could be the
only key to easing public acceptance of
biotechnology," says Allan Buckwell, an agricultural
economist at Wye College near Ashford, Kent.

Buckwell presented his findings in Brussels earlier this
month. He says that similarly stringent
segregation--although not on the basis of genetic
modification--is already widespread. "Different
varieties of wheat, for bread or pasta, are already
strictly separated from farm gate to production plant,"
he says. And in the US, soya growers already
distinguish beans used in different kinds of tofu for
export to Japan.

The cost of such segregation is not prohibitive, say
Buckwell and his colleague Graham Brookes. For
example, soya growers and processors in the US
separate and label beans with different protein and oil
contents for an extra cost of just 6 to 9 per cent
compared with unsegregated beans. Soya growers in
Brazil distinguish GM from non-modified soya for a
premium of 10 to 15 per cent. European dealers
separate maize with a high oil content for 17 per cent
extra cost, while US producers do it for 6 per cent.
Canadian farmers distinguish GM from normal oilseed
rape, or canola, for an 8 per cent premium. And costs
will come down, says Buckwell, if segregation
becomes widespread.

The organisation that commissioned the Wye College
study remains sceptical, however. The Food Biotech
Communications Initiative, which represents
companies such as Monsanto, Coca-Cola and Nestlé,
concludes that segregation will increase food costs by
"as much as 150 per cent".

But this interpretation assumes that food labelled as
non-GM has to be absolutely pure. In practice,
regulators are likely to allow food to carry such a label
if contamination with GM materials is below a certain
level. The EU, which is currently debating its labelling
criteria, is considering tolerances for GM
contamination for individual ingredients of around 1
per cent.

Dispatches from the killing fields
From New Scientist, 27 February 1999

David Concar

PERHAPS the most serious charge levelled
against crops engineered to produce insecticidal toxins
is that they will poison beneficial insects as well as
wiping out pests. The latest findings will fuel the
debate over the environmental safety of these crops
by giving both sides more ammunition.

One unpublished study, which looks at the impact on
insects of a bacterial toxin engineered into maize,
suggests the toxin's effects mysteriously increase as it
passes along the food chain. But another team is
disputing earlier claims that ladybirds are harmed by
plants that produce a protein toxic to aphids and other
sap-sucking pests.

Experts can't agree on exactly what the two studies
mean--particularly since any harmful effects of
insecticidal GM crops must be balanced against the
probable benefits of reduced pesticide use in fields
where the plants grow. Everybody accepts that plants
producing insecticidal toxins will reduce the number
and nutritional value of the pests that beneficial
insects feed on, but confusion surrounds the extent to
which the toxins poison predatory insects directly.

At the Swiss Federal Research Station for
Agroecology and Agriculture near Zürich, Angelika
Hilbeck and her colleagues say they have found
evidence confirming that lacewings, which eat
caterpillars and aphids, can be poisoned by an
insecticidal toxin engineered into maize. The gene for
this toxin, called Bt, comes from the bacterium
Bacillus thuringiensis.

Hilbeck raised a red flag about the effects of Bt toxin
on lacewings last year (This Week, 2 May 1998, p
21). In later experiments, her team fed identical
quantities of purified Bt toxin directly to lace-wing
larvae or via caterpillars that had consumed the toxin.
Fifty per cent more lacewings died after eating the
caterpillars. Hilbeck believes that the toxin became
more potent, perhaps because its chemical structure
was altered.

Her results may require changes in the way that
biotech firms test for any "collateral damage" their
crops might cause. They tend to feed the engineered
toxins directly to beneficial predators, rather than
through their prey. "You need to use a realistic route
of exposure," says Hilbeck.

Meanwhile, researchers led by John and Angharad
Gatehouse at the University of Durham have studied
what happens to ladybird larvae fed aphids that had
eaten a purified lectin protein from a snowdrop. This
is the same protein that was engineered into the
potatoes that sparked Britain's current GM food
scare.

Fears for the safety of beneficial insects surfaced in
1997, when a team led by Nick Birch of the Scottish
Crop Research Institute found evidence that eating
aphids reared on transgenic potatoes reduced the
lifespans and egg production of ladybirds (This Week,
1 November 1997, p 4). Now the Durham team
suggests the lectin is not acutely toxic to ladybirds.
The lectin stunted the growth of aphids, but when the
ladybird larvae were given more aphids to
compensate for the aphids' small size, they developed
normally to the pupal stage.

Seriously silly - Angst about GM foods is creating a farcical double standard in our thinking

Editorial
From New Scientist, 27 February 1999

AS EVERY fan of Monty Python knows, sketches can
become too absurd for their own good. That's what seemed
to be happening to Britain's great genetically modified food
saga earlier this week when it emerged that scientists at the
nation's biggest biotech company may have been breaking
the letter of the law when they merrily tucked into tomatoes
that had been genetically modified.

The newspaper scoop claimed that government officials
would now have little option but to investigate on the
grounds that seeds from the tomatoes could have passed
through the scientists and germinated in a sewage farm. To
date, only GM tomato paste, which contains no seeds, has
been approved for sale in Europe. The scientists were
rumbled when a photographer snapped them (see p 7)
munching tomatoes as part of a stunt to reassure the nation
about GM food.

It sounds like a spoof but in the present climate anything is
possible. Are officials really concerned about this petty
breach of regulations? Or are they merely playing a joke on
the media and its current obsession with all things GM?

Either way, the story exposes a serious issue. While we
worry about the hazards of GM crops (would it really matter
if a GM tomato germinated in a sewage farm?), we
apparently care little about the environmental dangers of
conventional crops. This double standard is reflected in
European Union legislation, which manages to be both
stringent for GM crops and virtually nonexistent for
conventional varieties.

Since GM farming seems fraught with potential hazards, you
could argue that this is justified. Looking at the facts,
however, suggests not (see p 4). Cut through the anti-biotech
propaganda and you find that there is nothing about GM
crops that gives them any special power to create
superweeds and landscapes chemically cleansed of wildlife.

But we should already know that. Across Europe, farmland
wildlife--especially birds --has been in decline for decades,
long before GM crops caught the eye of pressure groups.
The problem has been caused by the everyday use of highly
toxic chemical sprays, by ripping up hedgerows, and by the
relentless spread of intensive farming practices which we
have never quite had the collective energy or will to resist.

The question that really matters in the GM debate is whether
genetic engineering simply offers us more of the same or a
chance to farm more intelligently. Or rather this is what
matters in Europe. In the US, farmland wildlife is not such
an emotive issue because most of the nation's biodiversity is
locked up in vast national parks. Pocket-sized nations like
Britain, by contrast, expect the countryside to provide us
with cheap food, romantic landscapes and a home for our
wildlife all at the same time.

Will genetic engineering help us get what we want? Without
a lot more research into things such as the impact on wildlife
of genes which produce "natural" insecticides, and the pros
and cons of herbicide-resistant crops, it is difficult to give a
defini-tive answer. But what is clear already is that the way
farmers use these crops will be crucial.

In the hands of an enlightened farmer, crops that have been
engineered to be resistant to herbicides could, paradoxically,
work wonders for our herbivorous insects and songbirds by
enabling the farmer to let weeds grow alongside crops for
longer, secure in the knowledge that they can be eradicated
later in the season. In the hands of someone more ruthless,
the same crops could be a recipe for a sterilised landscape.

The story is similar with crops engineered to be resistant to
insect pests. Ecologists worry about these crops because
they are designed to produce a steady supply of a natural
insecticide that could harm beneficial predators such as
ladybirds (see p 5). They argue that the wider effects of this
could be quite different from those of chemical sprays
which, because they are used intermittently, can allow insect
populations to recover. To minimise any problems, it may be
necessary to set aside areas of land to serve as GM-free
refuges for insects.

In other words, it all comes down to the farmers. Again.
Strange, then, that amid the fuss there has so far been little
discussion about these custodians of the environment. Egged
on by pressure groups, people have been asking whether
they can trust the biotech industry and its political allies.
Perhaps they should also be asking whether they can trust
the farmers.
