vs Hysteria

MEXICO CITY
- In 2000, I served on a joint U.S.-European Union Biotechnology
Consultative Forum - appointed by President Clinton and Romano Prodi,
president of the European Commission - to look at the full range
of issues that have polarized thinking about biotechnology, especially
in food and agriculture, on both sides of the Atlantic.
While significant
differences of opinion existed - mainly related to the regulatory
structure on certifying agri-biotech products - most of the 20 U.S.
and European experts on the panel agreed that agricultural biotechnology
holds great promise to make dramatic and useful advances during
the 21st century. The most prestigious national academies of science
in North America and Europe (including the Vatican), also have come
out in support of genetic engineering to improve the quantity, quality,
and availability of food supplies.
Unfortunately,
the debate about the safety and utility of genetically modified
(GM) crops continues to grow, and now looks to be heating up further.
The U.S. is considering filing a challenge at the World Trade Organization
to break the European Union's four-year moratorium on importing
GM crops. Although the European Commission agrees that the ban needs
to be lifted, various member states refuse to do so until more stringent
GM labeling regulations are put in place.
The U.S. is
contemplating a WTO suit because European resistance to GM foods
is increasingly influencing the trade policies of other nations,
to the point where some African governments recently have turned
down American GM grain intended for starving people. U.S. Trade
Representative Robert Zoellick says he has information that several
European countries are threatening to make economic aid to developing
countries contingent on whether they prohibit biotech crops. If
this is true, it would be tragic and grossly irresponsible.
Although there
have always been those in society who resist change, the intensity
of the attacks against GM crops from some quarters is unprecedented
and, in certain cases, even surprising, given the potential environmental
benefits that such technology can bring by reducing the use of pesticides.
Genetic engineering of crops - plant breeding at the molecular level
- is not some kind of witchcraft, but rather the progressive harnessing
of the forces of nature to the benefit of feeding the human race.
The idea that a new technology should be barred until proven conclusively
that it can do no harm is unrealistic and unwise. Scientific advance
always involves some risk of unintended outcomes. Indeed, "zero
biological risk" is not even attainable.
Zambian President Levy Mwanawasa says he's been told by anti-biotechnology
groups that donated American corn is "poison" because
it contains genetically modified kernels. Based on such misinformation,
he is willing to risk thousands of additional starvation deaths
rather than distribute the same corn Americans have been eating
for years with no ill effects.
Some other
African leaders whose people also are facing hunger and starvation
say they're afraid to accept genetically modified corn because its
pollen will "contaminate" local corn varieties with dire
environmental consequences. Also, they say that they hope to export
corn to Europe in the future and fear that their products would
be rejected if genetically modified foods were allowed to enter
their countries.
These concerns
are unfounded. Temperate-zone corn (either GM or normal) will not
grow well in tropical African ecologies and, moreover, it has yellow
grain while Africans prefer white grain. Thus, even if a curious
farmer were to plant some GM grain received as food aid, its continued
presence in the field is unlikely. Certainly in the case of Zambia,
a land-locked country with poor transportation and low agricultural
productivity, the prospects for exporting corn to Europe in the
foreseeable future are almost zero.
If low-income,
food-deficit nations - which desperately need access to the benefits
of science and technology - are being advised by governments and
pressure groups in privileged nations to reject biotechnology, based
on ideologically inspired pseudo-science, there is reason for serious
concern. Of course, proper safeguards need to be put in place in
Africa and elsewhere to regulate biotechnology research and the
release of GM products. But to attempt to deny such benefits would
be unconscionable.
Current GM
crop varieties that help to control insects and weeds are lowering
production costs and increasing harvests - a great potential benefit
to all Third World farmers. Future GM products are likely to carry
traits that will improve nutrition and health. All of these technologies
have more benefits to offer poor farmers and consumers than rich
ones.
For example,
Kenya is ready to field-test virus-resistant sweet potatoes that
should yield 30% to 50% more of this important food staple. Virus-resistant
bananas and potatoes have already been bred, but are being barred
in African countries where people urgently need their higher yields.
Indian researchers are developing a vaccine against the epidemic
livestock disease, rinderpest, which can be genetically engineered
into peanut plants. African farmers would be able to protect their
draft animals simply by feeding them the peanut plants - again if
biotech is allowed.
The needless
confrontation of consumers against the use of transgenic crop technology
in Europe and elsewhere might have been avoided had more people
received a better education in biological science. This educational
gap - which has resulted in a growing and worrisome ignorance about
the challenges and complexities of agricultural and food systems
- needs to be addressed without delay. Privileged societies have
the luxury of adopting a very low-risk position on the GM crops
issue, even if this action later turns out to be unnecessary. But
the vast majority of humankind does not have such a luxury, and
certainly not the hungry victims of wars, natural disasters, and
economic crises.
Without adequate
food supplies at affordable prices, we cannot expect world health,
prosperity, and peace. Responsible biotechnology is not the enemy;
starvation is.
