consumers share the enthusiasm. It's as likely as not that you know GMOs
by their stock term of derision: Frankenfoods. The moniker reflects a
broad spectrum of concerns: Some anti-biotech activists argue that these
organisms will contaminate their wild cousins with GM pollen and drive
native plants extinct. Others suggest that they will foster the growth
of "superweeds"-plants that develop a resistance to the herbicides many
GMOs are engineered to tolerate. And yet others fear that genetic
alterations will trigger allergic reactions in unsuspecting consumers.
Whether or not these concerns collectively warrant a ban on GMOs-as many
(most?) environmentalists would like to see-is a hotly debated topic.
The upshot to these potential pitfalls, however, is beyond dispute: A
lot of people find this technology to be creepy.

Whatever the specific cause of discontent over GM crops, popular
resistance came to a head in 2000, when the National Organic Program
solicited public input on the issue of whether they should be included.
In response, sustainable-food activists deluged officials with a
rainforest's worth of letters-275,000, to be exact-beating the measure
into oblivion. Today, in the same spirit, environmentalists
instinctively deem GMOs the antithesis of environmental responsibility.

Many scientists, and even a few organic farmers, now believe the 2000
rejection was a fatal rush to judgment. Most recently, Pamela Ronald, a
plant pathologist and chair of the Plant Genomics Program at the
University of California-Davis, has declared herself one such critic. In
Tomorrow's Table: Organic Farming, Genetics, and the Future of Food
<http://www.amazon.com/gp/product/0195301757?ie=3DUTF8&tag=3Dslatmaga-20&=
lin

, she
argues that we should, in fact, be actively merging genetic engineering
and organic farming to achieve a sustainable future for food production.
Her research-which she conducts alongside her husband, an organic
farmer-explores genetically engineered crops that, instead of serving
the rapacity of agribusiness, foster the fundamentals of sustainability.
Their endeavor, counterintuitive as it seems, points to an emerging
green biotech frontier-a hidden realm of opportunity to feed the world's
impending 9 billion a diet produced in an environmentally responsible
way.=20

To appreciate how "responsible genetic modification" isn't an oxymoron,
consider grass-fed beef. Cows that eat grass are commonly touted as the
sustainable alternative to feedlot beef, a resource-intensive form of
production that stuffs cows with a steady diet of grain fortified with
antibiotics, growth hormones, steroids, and appetite enhancers that
eventually pass through the animals into the soil and water. One
overlooked drawback to grass-fed beef, however, is the fact that
grass-fed cows emit four times more methane-a greenhouse gas that's more
than 20 times as powerful as carbon dioxide
<http://www.slate.com/id/2178595/> -as regular, feedlot cows. That's
because grass contains lignin, a substance that triggers a cow's
digestive system to secrete a methane-producing enzyme. An Australian
biotech company called Gramina has recently produced a genetically
modified grass with lower amounts of lignin. Lower amounts of lignin
mean less methane, less methane means curbed global warming emissions,
and curbed emissions means environmentalists can eat their beef without
hanging up their green stripes.=20

Another area where sustainable agriculture and genetic modification
could productively overlap involves nitrogen fertilizer. A plant's
failure to absorb all the nutrients from the fertilizer leads to the
harmful accumulation of nitrogen in the soil. From there it leaches into
rivers and oceans to precipitate dead zones so choked with algae that
other marine life collapses. In light of this problem, Syngenta and
other biotech companies are in the process of genetically engineering
crops such as potatoes, rice, and wheat to improve their nitrogen uptake
efficiency in an effort to diminish the negative consequences of
nitrogen fertilization. Early results suggest that rice farmers in
Southeast Asia and potato farmers in Africa might one day have the
option of planting crops that mitigate the harmful effects of this
long-vilified source of agricultural pollution.

Animals, of course, are just as modifiable as plants. Livestock farmers
have been genetically tinkering with their beasts for centuries through
the hit-or-miss process of selective breeding. They've done so to
enhance their animals' health, increase their weight, and refine their
fat content. Breeding animals to reduce environmental impact, however,
hasn't been a viable option with the clunky techniques of conventional
breeding. But such is not the case with genetic engineering.=20

Case in point: Canadian scientists have recently pioneered the
"enviropig," a genetically modified porker altered to diminish the
notoriously high phosphorous level of pig manure by 60 percent. Like
nitrogen, phosphorous runoff is a serious pollutant with widespread
downstream consequences. But with the relatively basic insertion of a
gene (from E. coli bacteria) that produces a digestive enzyme called
phytase, scientists have provided farmers with yet another tool for
lessening their heavy impact on the environment.=20

When commercial farmers hear about GM grass, increased nitrogen uptake,
and cleaner pigs, they're excited. And when they hear about other
products in the works-genetically modified sugar beets that require less
water and have higher yields than cane sugar; a dust made from
genetically modified ferns to remove heavy metals from the soil;
genetically modified and edible cotton seeds that require minimal
pesticide use-they're also excited. And they're excited not only because
these products have the potential to streamline production, but also
because GM technology allows them to play a meaningful role in reducing
their carbon footprint.=20

However, with the exception of the modified sugar beets, the GMOs
mentioned in this article are not currently on the market. The
cutting-room floors of research laboratories all over the world, in
fact, are littered with successful examples of genetically engineered
products that have enormous potential to further the goals of
sustainable agriculture. Demand for these products remains high among
farmers-it almost always does-but food producers fear the bad publicity
that might come from anti-GMO invective.=20

Given the potential of these products to reduce the environmental impact
of farming, it's ironic that traditional advocates for sustainable
agriculture have led a successful campaign to blacklist GMOs
irrespective of their applications. At the very least, they might treat
them as legitimate ethical and scientific matters deserving of a fair
public hearing. Such a hearing, I would venture, would not only please
farmers who were truly concerned about sustainability, but it would
provide the rest of us-those of us who do not grow food for the world
but only think about it-a more accurate source of scientific information
than the back of a miso jar.
