enough to use biotechnology to increase<br />
the number or types of cattle, for<br />
instance, if this reduces local genetic<br />
diversity or ownership, the ability to<br />

unexceptional at best and possibly counter-productive at worst. To the degree that it might<br />
offer benefits, these are disputed and either the industry or regulators, or both, have not<br />
risen to the challenge of closing the research uncertainties. The scientific risks are both<br />
plausible and demonstrated if not always conclusive outside of the laboratory or field test.<br />
The legal risks have been amply demonstrated.<br />
Until recently, it was thought that “there are fewer options available than previously to<br />
address current problems through traditional breeding techniques” and that genetic<br />
modification technologies would largely replace classical breeding. The science of plant<br />
breeding is still waking up from this transgenic dream. Although genetic modification<br />
technologies have proven to be very powerful for introducing single gene traits (for example,<br />
resistances to insects and herbicides), the success rate for more complex traits, determined<br />
by numerous interacting genes, is much lower (Zamir, 2008, p. 270).<br />
The authors of the Assessment were not depressed by Zamir’s prognosis. They<br />
believed that there was reason to be optimistic that agriculture could be sustainable and<br />
more productive either with or without modern biotechnology (Tilman et al., 2002).<br />
Traditional breeding technologies have been immensely successful, and indeed are largely<br />
responsible for the high yields associated with contemporary agriculture. These technologies<br />
should not be considered passé or out of date…This is because selective breeding operates<br />
on whole organisms – complete sets of coordinated genes – while genetic engineering is<br />
restricted to three or four gene transfers with little control over where the new genes are<br />
inserted. For the most important agronomic traits, traditional breeding remains the technology<br />
of choice (Varzakas et al., 2007, p. 336).<br />
Like all visions, the Assessment’s will be incomplete or wrong in some details, but it<br />
is a vision that arises from the largest single research effort on this topic in all of human<br />
history. It is the most authoritative statement on current knowledge.<br />
The Assessment found that the drive to use the private sector for such an enormous<br />
proportion of agriculture research innovation fails to be relevant to the circumstances and<br />
needs of poor and subsistence farmers (Tilman et al., 2002).<br />
There is a vast difference between what happens in the fields of a farmer growing just one or<br />
two different crops on 500 hectares in Iowa and another growing many more different crops<br />
