Indian farmersí protests against the Monsanto-Mahyco field trials of genetically modified (GM) Bt-cotton during 1998-99 highlighted global controversies surrounding genetic engineering technology in agriculture. These protests drew the support of anti-GM forces across the world, raising questions such as: what do the protesting impoverished, small cotton farmers in southern India have in common with, e.g., the protesters who impeded WTO negotiations in Seattle? Where, if at all, do their interests coincide?
Is
the problem largely technological (according to protesters in USA and Europe),
or
is
it largely societal (according to protesters in India and other parts of
Asia)?
Molecular biological, organismal, and ecological issues surrounding the Bt-cotton project are examined in order to identify the level of organization at which known and potential problems arise and, thereby, to identify the level/s at which such problems are best addressed.
Protests in the two nations apparently were shaped by differing dominant concerns: socio-economic in India, ecological in the USA. However, in both cases, these dominant concerns obscure other important aspects of the issue, and are partly a consequence of distorted perceptions of the underlying technological issues.Some observations
In India, protesters were largely led by small farmers reacting to actual (non-GM) and potential (GM-related: 'terminator' technology, wrongly equated with all GM) agricultural problems related to cotton; another issue was the non transparent regulatory process. The biological questions raised in here and elsewhere4 were not at issue in the protests, even though answers to these questions are critical for a better understanding of the regulatory process.
In the USA, protesters were largely led by organic farmers and environmentalists reacting to potential ecological threats posed by all GM crops. A technological means of safeguarding intellectual property rights (IPR's), terminator technology, was seen as a 'moral' problem; however, a social means of doing the same, via legal measures, was neither widely discussed, nor viewed as a problem. The regulatory process (while it could be improved7) is relatively transparent and addresses several potential biological problems.
Issues surrounding GM technology in the two nations are both technological and societal in nature. However, in public discourse in the US technological issues prevail, while in lndia societal issues do so. This apparent difference between the two nations hides important similarities:Some conclusions
in both nations protests arise from dominant societal concerns that represent the sum of technological and societal forces, some of which are identical. It is misleading to characterize the issues in terms of EITHER technological OR societal. in both nations a distorted understanding of technology played an important role in shaping public perceptions. Scientists have an obvious role in clearly presenting the technological issues while separating them from the societal ones, as well as in keeping the regulatory process transparent. in the prevailing equations in the two nations it is around a societal issue, IPR's, that disparate interests converge. The 'terminator' technology was patented to fulfill a perceived societal need: a commercial interest to protect IPR's. Monsanto, representing this commercial interest, is merely a convenient target.
Bt (Bacillus thuringiensis toxin) technology: general technological features and issues
Molecular biological, organismal and ecological (including agricultural)Bt toxins comprise a large family of proteins produced by the bacterium, Bacillus thuringiensis. The protein, in crystalline form, is deposited on the bacterial cell wall and is toxic to lepidopteran insects (moths, butterflies) on ingestion and digestion. CryIAc is one of these proteins, produced by the cryIAc gene. Bollgard gene is a modified version of the cryIAc gene derived from the strain Btk HD-73. Bt toxins have been used against crop pests (e.g., by organic farmers in the US as bacterial sprays); however, affected insects may be pestilential, benign, or beneficial1.
Resistance to Bt (CryIAc) toxin is likely to evolve under continuous selection pressure in variable populations, in absence of non-Bt plant refuges for susceptible insects and high toxin levels to kill semi-resistant heterozygotes

Loss of an environmentally benign pesticide, Bt, is likely to occur due to evolution of resistance. What are the costs and benefits of this potential loss?
