enthusiastically taken up for purely commercial reasons. Thus we find computers carrying crippleware which effectively disables programs, and ‘terminator technology applied to seed production. A closer look at the latter will show just how far commerce can deviate from common sense in its blinkered pursuit of profit. (In so doing, I shall draw heavily on a case study by Thomas Petersen and Bryony Bonning of Iowa State University in its Bioethics Journal). The so-called ‘trait protection system’ (which is covered by US patent no: 5723, 765) ensures the non-viability, or sterility, of the offspring seed of plants grown from parent seed which has been genetically engineered specifically to produce this outcome. Consequently, farmers who purchase this seed from agribusiness companies – primarily because it has been genetically engineered to produce a much higher yield – are prevented from harvesting the offspring seed for growing the next crop, and obliged to purchase more seed for this purpose. Alarmingly, the process of ensuring non-viability also entails chemically treating the parent seed. The implications of this technology are multifarious and often undesirable, notwithstanding the fact that it is likely to result in significantly higher yields: for one thing, a loss of biodiversity is likely to ensue, both on account of native seed being replaced by genetically modified seed, and the fact that not many varieties of any crop are suitable for genetic engineering. It also has to be said that this new technology poses the risk of killer genes being transmitted to related species of plants in the locality via pollen, and potentially wiping them out. This new technology may also do away with the role farmers have traditionally fulfilled of
