We're just at the tip of the iceberg of an enormous number of things that will
be technically possible to do with plants. Some folks are talking about how
they are going to change the qualities of plants so that they'll be able to do
bio-remediation and clean up toxic sites. To some extent, that is a viable
technology and it's a sustainable way of dealing with complex issues. ...
We're going to find more examples where [it's going to be much easier to]
switch off a gene or an enzyme in a plant, or add some new component. [For
instance], if we can just cut down the amount of lignin in the poplar trees
that we're growing for paper pulp to make newspapers, [we'll get] less lignin
contamination in streams and waterways. That makes a lot of sense. ... [Over
time], the power of genetics--[which can provide] a sustainable modification of
a biological resource--is going to be the much-preferred avenue over using
cost-intensive industrial processes to do the same thing.

... If we use high-yield technology, which we have done beautifully in the last
50 years, to increase the food that we need, we leave undisturbed vast tracts
of marginal land which, if we opened to cultivation because of lack of rainfall
or topography, would erode badly. They would become unproductive in a few
years. Instead, [using] high-yield [agricultural practices] on the land [that
is] best suited, you leave undisturbed many of these areas for wildlife
habitat, for outdoor recreation, and for forestry. ...
There are many other things. Stop to think what would happen to corn production
if you could put a gene into it that will withstand 3 or 4 degrees of frost.
Corn is one of the most sensitive--it and beans--to light frost. Then you
could plant earlier in the spring, when moisture is more plentiful. ... It will
increase yield. It will shift corn production to earlier planting. We are
just seeing some of the first things that have been useful.

[Why use the BT gene to modify crops?] ...
Farmers are incredibly productive, but it does come at a price. There is a lot
of contamination of soils and groundwater with the excess use of chemicals that
are used to control weeds and insects and pests. So this was an obvious area
that biotech could very quickly address issues of interest to the farming
community. ... At that point in time, the biotech companies weren't thinking
specifically of the consumer. They really were thinking of the farmer. ...
Last year, 55 percent of all soybeans were genetically engineered for another
type of resistance gene, and this was herbicide tolerance. What this herbicide
tolerance gene does is allow a far more environmentally compatible
herbicide--glyphosate--to be used to control weeds. ... A recent report from
the U.S. National Food and Ag Council in Washington has shown that using
herbicide-tolerant soybeans, there was a savings of $280 million by farmers in
1998. This allowed them to use just a single herbicide. They only had to
spray if the weeds emerged. They didn't have to use multiple sprayings or
pre-sprayings. Likewise, they didn't have to use complex cocktails of really
pretty nasty herbicides. ...
Take corn and cotton. What kind of pathogens attack these crops?
The main pathogen, especially for corn, is European corn borer. That
particular pathogen comes up through the stalk of the plant itself, and it's
very difficult to get at because it's literally inside the stalk, and you
really oftentimes don't realize you have a problem until the ears fall off.
That's not very good for farmers, and there's no really good way of being able
to control them right now, even using traditional chemical pesticides.
With the BT gene in the corn itself, when the larvae eat [it], they are
immediately affected. If you look at the two plants--the control plant and the
engineered plant--it's like night and day. The control plant is just
completely infected with the European corn borer. The BT plant is completely
clean.

Charles Margulis
Farmers have been among the first beneficiaries [of BT crops]. A cotton
farmer uses less pesticides and grows better cotton. He's saving his
environment. How do you answer him?
I would say that he's the exception rather than the rule. ... Even the biotech
industry's own study on BT crops showed, at best, cotton farmers are seeing
about a 12 percent decrease in chemical applications. ... Once those [insects
that are resistant to BT] evolve, you're going to be stuck going back to that
biotech company, either for more toxic chemicals or for the next generation of
genetically engineered crops. They're going to be more and more costly, and
keep you more and more dependent.
It's the same kind of treadmill that farmers have seen from the pesticide
industry for 50 years. The average life span of an agri-chemical is about 3 to
5 years. Then nature evolves, the chemical doesn't work anymore, and farmers
have to go back to the company for the next greatest thing. ...

Jeremy Rifkin
I visited a farmer in the Midwest, and they just used two applications of
Roundup Ready, one at the beginning of the season and one halfway through.
Much less than they've ever used before. ...
I know quite a few farmers all over the United States who have tried this and
have said the opposite, that they have to use more herbicides, not less. The
same holds true with BT. Monsanto says, "We're going to introduce a little
gene into the plant that codes for a pesticide." Every cell of the plant is
producing that pesticide, so the insect tries to eat the plant and dies when it
tries to digest the material. Monsanto says, "This is a leap forward. We're
ending pesticides, groundwater contamination."
Well, yes and no. Yes, they're ending the use of pesticides. But now they're
introducing more toxin than they ever introduced with pesticides. When you
spray a pesticide, it's infrequent, it's periodic. When you are putting the
same toxin in the form of a gene into the plant, that plant is producing that
toxin 24/7, perpetually over millions of acres. ... A major study just came out
in Science or Nature this year showing that when you
introduce the gene for toxicity, it is going into the ground soil. ...

[With genetic engineering], we can put things like vitamin A into a rice plant.
... It's going to solve major problems in the developing world, as to [the]
availability of food materials for good nutrition.
[I know] a standard response is, "Well, they should just be eating more green
leafy vegetables." I've been to India. I've stayed in a very nice hotel in
[the] center [of] New Delhi. Families [are] living on the sidewalk on an old
patch of blanket. ... They no longer have a little garden plot to grow their
materials. They're stuck in a concrete jungle someplace [where] they don't
have access to green leafy vegetables and they're living on a handful of rice
every day. The Rockefeller Foundation and others [are] recognizing this, and
they have focused on issues like [changing] the quality of that food that they
do have available. ...

Some environmental groups argue for a return to another way of life. "We
have enough food. We just need to distribute it." They're not moved by your
environmental arguments, and they're trying to escape from your Third World
developing country arguments.
It would be wonderful if we could all live in a bucolic Turner chocolate-box
environment, where we all are back working on the earth, looking like a scene
from American Gothic. But that's not a reality. ... The reality is, if you're
going to look at the productivity that you could achieve by going back to
zero-input agriculture, versus what you can achieve using biotech means, they
just do not balance up. The costs would literally skyrocket. You can even see
that today, with the cost of organic produce. ...
Poor farmers in developing countries are organic farmers, and they don't
want to be. [They'd rather have access to the new agricultural
technologies.]
It's very difficult for them. I always like to quote a researcher from Kenya.
Florence Wambugu has said, "The real advantage of biotech is, it's package
technology in the seed." You don't have to teach these farmers new culture
practices. You don't have to get them to completely change the way they do
farming. You just give them a seed, and that increases productivity in that
seed itself. She said [that] for years people have tried to change cultural
practices of these farmers, and it just hasn't worked. It has been a complete
failure, because you have to modify infrastructure, you have to re-educate them
as to how to modify their farming practices themselves. But with biotech, the
technology is in a seed. All you have to do is give them the seed.
At this stage, about 40 different countries are capable of producing these
biotech products. They don't have to depend on the U.S. or First World countries
to provide them with this technology.

Jane Rissler, Ph.D.
Some say the greatest beneficiaries of this technology will be people in the
developing world. What do you make of these arguments?
I think it's a ploy. It's a ploy to convince relatively well-to-do people in
the industrialized world to approve of this technology. It's playing on the
guilt of relatively well-off people, that somehow if they don't approve of this
technology by agreeing to buy the products, the result will be people dying of
starvation in the developing world.
You don't believe this technology can help people in the developing
world?
The biggest problem behind hungry people is lack of money. It's not
technology. There's plenty of food right now, and there're people starving.
Putting vitamin A in rice, making high-protein corn, perhaps they have some
value. But the better approach would be that people could buy food that would
give a well balanced diet, instead of having to pile all the nutrients into one
type of food or two types of food. So I don't think we ought to be deluded.
Technology is not the obstacle to feeding people. It's poverty. ...
How about the idea of edible vaccines? Do you not see any benefit?
These are ideas that people have, and I think they have noble purposes. I
think that the problems are more complicated. ... I don't mean to be
disparaging of all these scientists who have really noble goals. But I do see
people perhaps overlooking more practical but less sensational solutions to
very important problems. ... It seems the sexy thing to do, to apply
biotechnology to a range of problems, without really considering that there may
be simple, practical, feasible alternatives.

Charles Margulis
Some people in the developing world, scientists, [support the development of
genetically modified foods]. It's not a fringe view [and Greenpeace will] have
to deal with this constituency, which is more sympathetic than Monsanto.
Monsanto and the biotech industry have used this as a public relations tool.
There are certainly voices from everywhere in the world who will be supportive
of biotechnology. But by and large, when it came down to their governments'
representatives, the developing world was united in saying, "We want the right
to say no to this technology." ...
We live in a world today where 800 million people a year are going hungry, in a
world that produces enough food for almost 9 billion people. Yet we only have
6 billion people on the planet. Why isn't that food being distributed more
equitably? It's because people who can't afford to buy food simply aren't
being given it. ...
But people in these countries don't want to be just fed food. They want to
grow their own.
In almost every country in the world, there is enough productive growth right
now to feed the population of that country. But many countries where people
are going hungry are exporting food. That's because food gets sold for a
profit. It doesn't get given away. And if people in that country can't afford
to buy it, it's going to be grown and exported.
