Scientists Admit Frankencrops Pollution is Inevitable

Background: Biotech industry scientists face contamination, liability problems
Now, in the immediate aftermath of the Chapela controversy and on the eve
of this year's BIO convention and Biojustice counter-events, the June
2002
issue of Nature Biotechnology (vol. 20) - probably the world's
most
prestigious journal devoted specifically to biotechnology -
offers
compelling new evidence that industry scientists are indeed quite
preoccupied
with the problem of GE contamination of non-GE crops. An
editorial and a
series of three research articles in this month's issue
makes it clearer than
ever, not only that contamination is undeniable, but
that industry-friendly
scientists are beginning to see the problem of gene
flow as a definitive obstacle
to the marketing of new generations of GE
crops:
"Second-generation crops, which involve output modifications (traits
with
health and nutritional benefits), will likely only be viable if their
purity
or quality can be assured, which is problematic given the difficulty
of
attaining gene containment. Third-generation crops with new
industrial,
neutraceutical, or pharmaceutical properties will likely require
effective
gene control systems or simply will not be permitted to be
released."
(S. Smyth, et. al., p.537)
While the Mexican evidence is never cited, examples such as the
triple-
herbicide resistant canola in Alberta (which is sprayed with the
herbicide
2,4D in an attempt to eradicate it), Starlink corn in the US
and
government-mandated destruction of contaminated crops in Europe are
cited as definitive examples that the debate over GE crops has evolved
to a qualitatively different level.
Evidence is cited from last
year's PNAS studies on Bt and monarch
butterflies suggesting that at least
10% of corn pollen is dispersed beyond
15 feet outside the corn field, and
at least 1% reaches beyond 150 feet;
canola pollen has been observed to
travel as far as 25 km..
Here are some other salient quotes:
From Nature Biotechnology's editorial (p. 527):
"There are nevertheless at least 44 cultivated plant species that have
the
potential to mate with one or more wild relatives somewhere in the
world.
With plenty of data suggesting that DNA flies all over the place down
on
the farm, evaluations of the risks associated with new cultivars usually
assume
that gene flow from crops to relatives can occur."
"Because gene containment is next to impossible with the current
generation
of GM crops, this discriminatory stance [i.e., regulations based
on "process
rather than products"] has led to several international
'incidents' over the
past few years."
"Current gene containment strategies cannot work reliably in the field."
"The adventitious presence of Starlink in tacos had no consequences
for
human health, but could the same be siad of a corps variety designed
for
biopharmaceutical production?"
From S. Smyth, et. al. (University of Saskatchewan), pp. 537-541:
"Currently the agrochemical industry faces two major challenges if it is
to
realize the potential of GM crops ... On the one hand, to pay for
large
development and commercialization costs, investors and firms that
have
funded GM-related technologies much capture a share of the return on
that
investment.
On the other hand, corporations and regulators must
also ensure that the new
traits and varieties created do not impose risks or
liabilities that offset
(or swamp) the value generated. At the farm level, in
particular, there is
signficant risk of profit reduction and for co-mingling
of plants with new
traits with other crops, creating potential new
liabilities."
"The libility cost of genes from GM crops 'escaping and going rogue'
or
comingling and adversely affecting quality of other plant-based products
is
significant."
"...any infestation of herbicide-resistant wild mustard above four
plants
per square meter would reduce the benefits of transgenic
herbicide-tolerant
canola to below zero."
"...honey shipments to the EU [from Canada] dropped $4.8 million
between
1998 and 2000 (or by 55%) to the lowest level in more than ten years.
. .
Recently the EU banned Canadian honey because of the inability of
Canadian
honey producers to guarantee the absence of pollen from GM plants
not yet
approved in the EU."
"In brief, plants and people cannot be trusted to do what markets require."
"Irrespective of scientific rationale, current political and social pressures
are likely to lead to more stringent regulation of future GM varieties."
The authors' main suggestion is that a comprehensive cost-benefit
analysis
of the release of terminator seeds be undertaken in order to
facilitate and
ultimately "justify commercialization" of terminator and other
"genetic use-
restriction technologies" (GURT's). Two other papers in the
June issue
address the wider scope of possible containment strategies,
including some
new approaches, as well as the development of molecular
methods to excise
selectable marker genes, such as the genes for antibiotic
resistance, that
are currently used to detect successful gene transfers in
the laboratory.
