"Genetically modified crops"have
become one of the privileged targets of the anti-globalisation movement.
In Britain, France and other countries, militant "greens" and irate small-farmers
have attacked and destroyed fields of experimental "GM" crops,
vilifying them both as symbols of multinational agribusiness,
and as a threat to the world's natural environment.
Yet how real
are the dangers, and why are scientists working to develop GM crops? Is
there any sound scientific evidence to back up the protestors' fears, or
are the protests largely motivated by ignorance? Is the anti-GM movement
progressive, or is it an ultra-conservative form of obscurantism, manipulated
by extremists ? Different people have different views on the matter, but
history shows that fundamental developments in science or technology have
always provoked a backlash motivated by fear or misunderstanding.
When industrial machinery began
to appear in British factories almost 200 years ago, factory-owners
were wildly enthusiastic; so were many workers. But there were other people
who took a different view. Groups known as the Luddites, opposed to the
mechanisation of factories, sprang up across Britain, adopting commando
tactics to break up new machinery in factories - claiming
that it would destroy jobs and change people's lives for the worse.
When the first steam trains appeared in the 1830's, they provoked violent reactions too; opponents claimed that they were dangerous, noisy and dirty, would destroy cities by fire, and kill people through speed. Some landowners resolutely refused to allow lines to be built over their land. Fifty years later, the arrival of the motor car was met with a similar mixed response - opponents arguing that "horseless carriages" were far too dangerous to be allowed on Britain's roads. For a while, the opponents almost won the battle, and until 1896, cars on Britain's roads had to be preceded by a man walking with a red flag.
Indeed, the history of scientific and technical progress is full of examples of resistance to progress - in a paradoxical illustration of Newton's third law of motion*.
This being the case, the vigorous reaction that is now taking place in Britain and several other countries against the introduction of genetically modified crops is not surprising; indeed, it is probably inevitable. Since the catastrophe of "Mad Cow Disease", - and in spite of the enormous benefits brought about by modern agricultural practice - agribusiness and scientific modern farming methods have become seriously contested in many quarters.
In Britain, the argument over GM crops has become the most contested scientific issue since the arrival of the atom bomb . In 1998 a public opinion poll showed that 77% of British people did not want genetically-modified crops to be grown in Britain - though only 58% were opposed genetic modification in principle. And in spite of historic parallels that tend to suggest that resistance to change is rarely effective in the long run, the controversy over genetically modified crops is perhaps more critical than most.
In spite of public apprehension, the government has continued to support research into GM crops, and today genetically engineered plants, some 400 hectares of them, are already growing in Britain, mostly in agricultural research centres, universities and plant laboratories. Here and there, fields of genetically modified crops have been planted and to the passer-by, they look no different from other fields.
In many ways, GM crops are not really very different
from others. Scientists have been selecting and "improving" crops for hundreds
of years, often by the slow and dubious method of "trial and error". Most
of the crops and fruit growing in today's fields are very different from
the varieties grown two centuries ago, and far more productive; far from
being "natural" plants, they are new strains that have been developed by
genetic selection of the best. "Genetic Modification" just takes
the process one stage further, allowing agricultural scientists to produce
new varieties with specific required qualities.
One of the main objectives in altering the genes
of certain plants is to make them resistant to disease and
to pests, and thus reduce the need for pesticides. Another is to make them
resistant to particular weed-killers, so that farmers can
spray fields knowing that the spray will kill almost all plants except
the selected crop that they are growing. Other genetic modifications
are aimed at producing plants that need less fertilizer or are more resistant
to drought, and thus need less watering. Most developments
in these directions are strongly positive in environmental terms.
They are also positive in human terms, and
development of drought-resistant and disease-resistant crops will
have major implications for the third world, where famine
is
a constant risk. It is therefore not surprising that developing nations
with large populations to feed, such as China and India, are keen supporters
of genetic research; unlike Europe and North America, with their
agricultural surpluses, many poorer nations already cannot produce enough
food to feed their populations.
In other developments, laboratories are genetically
incorporating vaccines - including hepatitis B and rabies
- into certain plants. Plant-based vaccines are potentially far cheaper
to produce and easier to store than their chemically-manufactured equivalents.
Countering these arguments, opponents of genetic
modification point to the enormous risks that could be involved. While
fears of "mad corn disease" are as yet purely
hypothetical, other risks seem more realistic. Greatest of these is perhaps
the fear that genetically modified crops could naturally interact with
other plants, producing super-resistant weeds that would create chaos in
agriculture. According to the Government's own advisory body
English Nature, genetic crops "pose a threat to all wildlife".
In a recent paper, English Nature scientists stressed that the introduction
of genetically modified plants might dramatically reduce plant diversity
in Britain, destroying fragile ecosystems and leading to the rapid disappearance
of certain species of plantlife, insects and birds.
Cynics might reply that species of plant life, insects
and birds have been disappearing for years already.
In the short term, the arguments
seems unlikely to go away. American farmers are already mass producing
genetically modified crops, and so far there has been no reported disaster.
That does not mean that disasters are impossible. In ten or twenty years'
time, we may have a better idea of how likely, or unlikely they are; in
the long run the argument about genetic modification will sort itself out
one way or another. Until then, it is up to each individual to weigh
up the pros and the cons and decide if the risks outweigh the advantages
or not.
