Just beyond the defunct Koloa Sugar Mill on the Hawaiian island of Kauai's
south shore are acres of cornfields that have sprouted over the past decade
in a state made famous by its pineapples, bananas and sugarcane crops.
Slightly out of place in the Aloha State, they otherwise look quite
conventional, although in fact they are not: The crop is among a bounty of
others in the state that are grown from seeds that have been genetically
engineered or modified (GM) to produce sturdier plants able to withstand
weather and disease as well as thrive in the face of insects and chemicals
sprayed on them to kill destructive weeds.


In front of one plot of corn stalks is a red and white sign warning,
"Danger: pesticides. Keep out." Tacked to it is a list containing 15
chemicals that may have been applied to the crop. In this case, the
chemicals circled are the herbicides pendimethalin (brand name: Prowl),
dicamba (Banvel) and atrazine, the latter of which is banned in the European
Union (E.U.) because of its link to birth defects in frogs that live in
groundwater contaminated with it.

I pass these corn fields every day when I go to the beach to go swimming,"
says Marty Kuala, 68, a 36-year resident of the town Koloa who worked in a
plant nursery (that grew native plants such as naupaka, a?ali?i, and naio)
in 2005. "It's kind of a new thing that we're starting to see these fields
[of genetically modified or engineered crops] all over the place. GMOs
[genetically modified organisms] are growing in the Mahaulepu area on
Kauai's south shore and even in the large populated areas of Lihue, our
biggest town."

This year, only 1.67 million tons of raw sugar were produced, nearly one
million tons less than just a decade earlier; only 13,900 acres (5,625
hectares) in the state were set aside for pineapples in 2006 [the latest
year for which pineapple stats are available) compared with a whopping
76,700 acres (31,039 hectares) in 1991.

The other crops vying for state land: flowers and nursery plants, macademia
nuts, coffee, milk, algae, tomatoes, bananas and papaya.

Genetically modified food has been a source of debate since hitting the
market in 1994. The E.U. had banned the imports of GM crops for 20 years,
however in 2006 the World Trade Organization (WTO) ruled that the ban
violated international trade rules. The U.S. Food and Drug Administration
(FDA) has deemed it safe and has so far declined to limit or block the
burgeoning industry.

The extraordinary biodiversity (and, so, native plants competing for space
and nutrients), along with the intractable problem of invasive species would
seem to make Hawaii the least likely place to grow controversial crops,
risking their uncontrollable spread. But scientists seed companies and some
scientists believe say the benefits outweigh the risks of damage to the
fragile ecosystem, most notably Hawaii's crop-friendly moderate year-round
climate?an average of 75 degrees Fahrenheit (24 degrees Celsius)?and its
open acreage. And over the past 10 years, Hawaii has become the locus for
genetically modified crop field trials and a microcosm for the controversies
over the safety of growing and eating transgenic food.

To date, Hawaii's fertile soil has nourished more than 2,230 field trials of
genetically modified (GM) crops, including corn, soybeans, cotton, potatoes,
wheat, alfalfa, beets, rice, safflower, and sorghum?more than any other
state. A total of 4,800 acres (1,940 hectares) of such crops now grow
throughout the state, some 3,500 (1,415) of which are corn and soybeans,
1,000 acres (405 hectares) of which yield genetically engineered papaya, and
the remaining 10 percent are field trials for new potential GM crops.
"Hawaii is ideally suited for field trials and seed production, because of
the climate and the ability to grow corn and soybeans 52 weeks a year," says
Cindy Goldstein, a spokesperson for Johnston, Ia.?based Pioneer Hi-Bred
International (a subsidiary of DuPont) in Waimea, Kauai. Her company has
been producing GM corn and soybeans in Hawaii since the mid-1990's, when the
FDA approved the crops for commercial sale.

Goldstein says that seed companies can harvest three to four yields of corn
per year in Hawaii compared with only a single yield in the continental U.S.
thanks to its temperate tropical climate. Other parts of the world with
similar climates may also be well suited for corn and soybean seed
production. But Goldstein notes that Hawaii has the added advantage of
extensive amounts of available land due to the downturn in sugar and
pineapple over the past decade, a victim of skyrocketing production costs
compared with lower rates in developing countries.

As a result, many U.S. seed companies, including Pioneer Hi-Bred, Monsanto
and Syngenta, have turned the Islands into a sprawling living nursery for GM
corn seed. Genetically engineered corn seed is now the top crop in Hawaii,
comprising 92 percent of the state's GM seed industry valued at $97.6
million for the 2006 to 2007 season.

"Genetically engineered crops can actually help our environment, help our
economy, and secure jobs for our agricultural workers," says Ching Yuan Hu,
associate dean of research at the University of Hawaii at Manoa's College of
Tropical Agriculture and Human Resources. Hu is quick to point out, however,
that he only supports the development of GM crops in which cross-pollination
with non-GM crops can be prevented to ensure that engineered traits will not
dilute the gene pool of conventional crops, thereby causing target species
to develop resistance.

The university is currently engineering seeds for disease-resistant bananas,
a new variety of papaya, and Spanish lime?plants that Hu deems safe. Hu
notes that it generally takes from seven to nine years to bring a new GM
seed to market.

But not everyone is on the GM bandwagon. Critics worry that the pests
genetically engineered crops were originally created to withstand will
eventually build resistance to the crop, and that the engineered traits will
spread virulently via the wind, birds and bees.

"One of the biggest concerns with growing crops like Bt [Bacillus
thuringiensis] corn [engineered to produce the pest killer, Bt, which has
been used for decades by organic farmers to control crop-eating insects] is
that you're putting insects under the greatest selection pressure to become
resistant to Bt, a natural insecticide," says Bill Freese of the Center For
Food Safety, an environmental advocacy group in Washington, D.C., that
promotes alternatives to unsustainable food technologies. He adds that if
insects become resistant to this natural pesticide, organic farmers may lose
one of their best and safest antipest weapons.

"The broader implications of growing GM crops is that it will create
unwanted genetic material and traits in a wider and wider swath of major
crops," such as spreading herbicide tolerance or pest resistance into wild
relatives and then outward from there, Freese adds.

Conventional Hawaiian papayas have already come under scrutiny by organic
farmers and environmental organizations in Hawaii for "genetic drift"?crops
grown from non-GM seeds that test positive for being GM. In response, South
Korea stopped buying papayas from the island of Hawaii, and Hawaiian papaya
farmers who ship to Japan now have to test their trees for contamination and
certify that they're "clean". In other words, these countries don't trust
the genetic integrity of Hawaii's "non-GM papayas," which in turn has
economically harmed many of the islands organic papaya farmers, and can lead
to them losing their organic certification.

There have also been questions about the safety of genetically engineered
foods. In Europe, the European Food Safety Authority determines whether new
GM products are safe for consumers and the environment. That view is then
considered by the 27 member states, which make the final decision. It
requires all genetically modified foods to be labeled, and, currently, only
one genetically modified crop?Bt corn?has been approved to grow in the E.U.
(mainly in Spain, but also in Germany, the Czech Republic and Portugal).

The FDA does not require GM foods to be labeled as such, insisting that
studies have shown it to be as safe as foods produced using conventional
breeding techniques. It is the seed companies that conduct the safety tests
for new GM food products, passing the safety and nutritional information to
the FDA for the agency's scientific evaluation.

"I haven't seen sufficient data from a legitimate organization without a
conflict of interest to show that the stuff is healthy or safe," says Lorrin
Pang, a public health specialist in Maui, and a consultant to the World
Health Organization on tropical diseases, "I haven't seen data that says it
isn't, either?but I'm from a drug and vaccine background that operates on
the precautionary principle: You don't give something to the public until
it's proven safe."

Pioneer Hi-Bred's Goldstein insists that foods made with genetically
modified ingredients are safe, noting that they have been in the U.S.
marketplace since 1996 and that "over a trillion meals containing biotech
ingredients have been consumed in the U.S. with no documented negative
health impacts."

The genetically modified seed biz may be booming in the 50th state, but not
everyone is pleased about it. The Hawaii County Council (county legislature)
last month voted to ban the growth of genetically modified taro (a tropical
plant whose potato-like root is a staple of the Hawaiian diet) and coffee on
the Big Island (Hawaii). The reason: pollen from GM crops could contaminate
the non-gm varieties and destroy farmers' livelihoods. The concern seems to
be greater with these products, because they?re specialty crops commonly
grown on the Islands, as opposed to corn, raising the possibility of
cross-pollination.

There is also an emotional element to banning GM taro. According to legend,
the taro plant originated when a child of the gods was born lifeless. From
the child?s grave sprouted the first taro plant, forever casting it as a
sacred subsistence food and an ancestor to native Hawaiians.

Despite the hoopla, Carol Okada, manager for the Plant Quarantine Branch of
Hawaii's Department of Agriculture, says the business is here to stay and
will still be booming in Hawaii 10 years down the road. "Even though it's
controversial here," she says, "the [GM] seed industry is now the No. 1
industry for us and it is very important in terms of the economy, dealing
with invasive species, and giving farmers choices."

The bottom line: Hawaii may be the GM crop test capital of the world, but
the debate over biotech foods is far from over.
