The use of genetically modified plants in agriculture (GM crops) is controversially discussed in academic publications. Important issues are whether the release of GM crops is beneficial or harmful for the environment and therefore acceptable, and whether the modification of plants is ethically permissible per se . This study provides a comprehensive overview of the moral reasoning on the use of GM crops expressed in academic publications from 1975 to 2008. Environmental ethical aspects in the publications were investigated. Overall, 113 (...) articles from 15 ecology, environmental ethics, and multidisciplinary science journals were systematically reviewed. Three types of moral concerns were used to structure the normative statements, moral notions, and moral issues found in the articles: concerns addressing consequences of the use of GM crops, concerns addressing the act (the technique itself), and concerns addressing the virtues of an actor. Articles addressing consequences (84%) dealt with general ecological and risk concerns or discussed specific ecological issues about the use of GM crops. Articles addressing the act (57%) dealt with the value of naturalness, the value of biotic entities, and conceptual reductionism, whereas articles addressing the actor (43%) dealt with virtues related to the handling of risks and the application of GM crops. The results of this study may help to structure the academic debate and contribute to a better understanding of moral concerns that are associated with the key aspects of the ethical theories of consequentialism, deontology, and virtue ethics.

Should we continue to support publicly funded research on genetically engineered herbicide resistant crops? In Part One, I discussed the difference between science and ethics, presented a brief history of weed control, and explained three moral principles undergirding my environmentalist perspective. I then argued that unqualified endorsement (E) of the research is unjustified, as is unqualified opposition (O). In Part Two, I argue against qualified endorsement (QE), and for qualified opposition (QO).

Recent advances in molecular genetics, plant physiology, and biochemistry have opened up the new biotechnology of herbicide resistant crops (HRCs). Herbicide resistant crops have been characterized as the solution for many environmental problems associated with modern crop production, being described as powerful tools for farmers that may increase production options. We are concerned that these releases are occurring in the absence of forethought about their impact on agroecosystems, the broader landscape, and the rural and urban economies and cultures. Many of (...) the benefits and risks associated with HRCs are not apparent to either the public, farmers, policy makers, or the scientific community. HRC technology raises moral issues in three areas: our duties toward the natural environment; our political and economic responsibilities to each other; and our communal character as one generation among many. We also need a rational basis on which to make evaluations of this new biotechnology. The technical aspects of their release require a logical guide to the ecological, environmental, and biological effects the release might have in sustainable agroecosystems. The initial step should include an assessment of the intrinsic qualities of the crop, the herbicide, and the resistance mechanisms. The second step should include an assessment of effects associated with population ecology, population genetics, environmental degradation, consumer health, and farm economic viability due to the resistant crop-herbicide pair. Herbicides have been used in crop production for nearly a half a century. There has been a tremendous increase in the use of these chemicals in that time. Society has seen the use of these chemicals not only help to feed many people, but also to bring costs not anticipated before the introduction of the chemicals. We need to draw on that long history of use and learn the lessons it can provide us as we approach the introduction and commercialization of the next generation of weed control technology, herbicide resistant crops. We also need to reflect on the lessons we missed during that half century because we spend more time imagining the possible benefits that would come from the technology than scrutinizing the possible harm.

A noticeable push toward using agricultural crops for ethanol production and for undertaking research to expand the range of possible biofuels began to dominate discussions of agricultural science and policy in the United States around 2005. This paper proposes two complementary philosophical approaches to examining the philosophical questions that should be posed in connection with this turn of events. One stresses a critique of underlying epistemological commitments in the scientific models being developed to determine the feasibility of various biofuels proposals. (...) The second begins with a broader set of questions about the philosophical goals of agriculture, then queries the place that a turn to biofuels might have within the philosophy of agriculture. Both are portrayed as viable and important. The paper itself is a preliminary stage-setting reflection on the need for these two types of philosophical inquiry. (shrink)
