Consumer Autonomy and Availability of Genetically Modified Food

The European Union’s policies regarding genetically modified food (GMF hereafter) are based on the precautionary principle and the requirement of respecting consumers’ autonomy. We ask whether the requirement of respecting consumers’ autonomy regarding GMF implies that both GMF and non-GMF products should be available in the market. According to one line of thought, consumers’ choices may be autonomous even when the both types of products are not available. A food market with only GMF or only non-GMF products does not strictly speaking compel people to buy the type of products available, and a possibility to refuse to buy is enough for consumers’ choice to be autonomous. According to another line of thought, the unavailability of GMF or non-GMF products restricts the autonomy of those consumers who are unwilling to use the only type of products (GMF or non-GMF) available in the market. From the point of view of autonomy, a food market with only GMF or only non-GMF products does not offer enough alternatives for consumers. Moreover, the whole point of the European Union’s requirement of respecting consumers’ autonomy is to enable an autonomous choice between GMF and non-GMF—not just to give a possibility to refrain from buying. However, this does not imply that producers, processors, wholesalers, retailers, or public authorities have a moral duty to see that there are both GMF and non-GMF products available in the market. The requirement to respect autonomy is prima facie in nature, and in the context of GMF, other prima facie requirements are often stronger and override it. Not only the consumers’ autonomy of choice but also environmental values, other people’s well-being, and the autonomous choice of farmers, retailers, and other relevant parties should be respected. Thus, according to the both lines of thought, the requirement to respect consumers’ autonomy of choice does not imply that there should be both GMF and non-GMF products available in the market.     

Ethics of Sustainable Development – a Study of Swedish Regulations for Genetically Modified Organisms

In spite of stricter provisions inthe new EU directive on deliberate release ofgenetically modified organisms (GMOs), criticsstill advocate a moratorium on permits forcultivation of GMOs. However, in an attempt tomeet concerns raised by the public, thedirective explicitly gives Member States thepossibility to take into consideration ethicalaspects of GMOs in the decision-making. Thisarticle investigates the potential effects ofsuch formulation by means of an empiricalanalysis of experiences gained the last yearsfrom similar Swedish regulations for GMOs,aiming at promoting sustainable development.The faulty implementation shown in the Swedishcase indicates that legal stipulations forethics as such have limited importance. It issuggested that public participation is animportant factor for successful implementationof the ethics of sustainable development.     

A Precautionary Approach to Genetically Modified Organisms: Challenges and Implications for Policy and Science

The commercial introduction of genetically modified organisms (GMOs) has revealed a broad range of views among scientists and other stakeholders on perspectives of genetic engineering (GE) and if and how GMOs should be regulated. Within this controversy, the precautionary principle has become a contentious issue with high support from skeptical groups but resisted by GMO advocates. How to handle lack of scientific understanding and scientific disagreement are core issues within these debates. This article examines some of the key issues affecting precaution as a legal standard and as an approach to the use of science in decision-making processes. It is pointed out that there is a need for reflection over the level of scientific evidence required for applying the precautionary principle as well as who should have the burden of proof when there are uncertainties. Further, an awareness of the broader scientific uncertainties found in GMO risk assessment implies that a precautionary approach must be elaborated: both for acknowledging uncertainties and for identification of scientific responses. Since precaution is an important issue within the sustainable development framework, it is suggested that sustainability can provide a normative standard that can help to reveal the influence and negotiate the importance of the various forms of uncertainty. Wise management of uncertainties and inclusion of normative aspects in risk assessment and management may help to ensure sustainable and socially robust GMO innovations at present and in the future.     

Ethics in the Societal Debate on Genetically Modified Organisms: A (Re)Quest for Sense and Sensibility

Via a historical reconstruction, this paper primarily demonstrates how the societal debate on genetically modified organisms (GMOs) gradually extended in terms of actors involved and concerns reflected. It is argued that the implementation of recombinant DNA technology out of the laboratory and into civil society entailed a “complex of concerns.” In this complex, distinctions between environmental, agricultural, socio-economic, and ethical issues proved to be blurred. This fueled the confusion between the wider debate on genetic modification and the risk assessment of transgenic crops in the European Union. In this paper, the lasting skeptical and/or ambivalent attitude of Europeans towards agro-food biotechnology is interpreted as signaling an ongoing social request – and even a quest – for an evaluation of biotechnology with Sense and Sensibility. In this (re)quest, a broader-than-scientific dimension is sought for that allows addressing the GMO debate in a more “sensible” way, whilst making “sense” of the different stances taken in it. Here, the restyling of the European regulatory frame on transgenic agro-food products and of science communication models are discussed and taken to be indicative of the (re)quest to move from a merely scientific evaluation and risk-based policy towards a socially more robust evaluation that takes the “non-scientific” concerns at stake in the GMO debate seriously.     

Genetically Modified (GM) Crops: Precautionary Science and Conflicts of Interests

Risk governance of GM plants and GMfood products is presently subject to heatedscientific and public controversies. Scientistsand representatives of the biotechnologyindustry have dominated debates concerningsafety issues. The public is suspicious withregard to the motives of scientists, companies,and political institutions involved. Thedilemmas posed are nested, embracing valuequestions, scientific uncertainty, andcontextual issues. The obvious lack of data andinsufficient information concerning ecologicaleffects call for application of thePrecautionary Principle (PP). There are,however, divergent opinions among scientistsabout the relevance of putative hazards,definition of potential ``adverse effects,' andwhether actions should be taken to preventharm. The reliance on the concept ofsubstantial equivalence in safety evaluation ofGM food is equally controversial. Consequently,value assumptions embedded in a scientificframework may be a barrier for employment ofthe PP. One of our major conclusions is thatprecautionary GMP usage requires riskassessment criteria yet undeveloped, as well asbroader and more long-term conceptions of risk,uncertainty, and ignorance. Conflicts ofinterest and public participation are otherissues that need to be taken intoconsideration. GMP governance regimes that arejustifiable from a precautionary and ethicalpoint of view must transcend traditionalscientific boundaries to include alternativescientific perspectives as well as publicinvolvement.     

Does Autonomy Count in Favor of Labeling Genetically Modified Food?

In this paper I argue that consumerautonomy does not count in favor of thelabeling of genetically modified foods (GMfoods) more than for the labeling of non-GMfoods. Further, reasonable considerationssupport the view that it is non-GM foods ratherthan GM foods that should be labeled.     

沙质滩涂中可溶性油的释放动力学研究

沙质滩涂对石油类污染物的吸附是一种物理吸附过程,在一定的条件下,吸附于沙质滩涂中的石油类污染物又可能释放出来,对滨海环境造成新的污染。在对滨海沙滩（胶州湾）沙质滩涂-水系统石油污染调查的基础上,选择代表性的沙滩进行取样,系统测定不同沙质滩涂对可溶性油的释放动力学过程,并分析了盐度、pH、温度和含沙量对释放作用的影响。结果表明,沙质滩涂对可溶性油的释放动力学曲线符合对数型,即随着时间的延续释放速度逐渐降低,沙质滩涂对可溶性油的释放平衡时间约为10h,沙质滩涂对可溶性油的释放量随盐度和pH的增大而减少,随温度、含沙量和振荡频率的增加而增加。     

Legal and Ethical Apprehensions Regarding Relational Object. The Case of Genetically Modified Fish

This paper is the result of a contribution between ethics and law, which will be used as thought-process tools, to address the complex issue of legal and ethical statuses of GM fish. To find answers, we propose to consider this issue from a wider angle, looking at the relations between the human, animal, and living worlds. We show that it is possible to construct other forms of intellectual logic that, without setting these worlds in opposition, do not lapse into relativism where boundaries are blurred. In this sense, we submit the hypothesis that ordered pluralism should help us to move past a mere Man–Animal relationship to reveal the entire complexity of relationships within mankind and between mankind and other (non-human) worlds alongside it and to which it belongs: the animal and living worlds. With this new logic, “animal ethics” and “animal law” are re-embedded into a set of relationships. This logic emerges from a new consideration: the nature of the contemporary objects we are dealing with. We shall call objects like genetically modified fish “relational objects” in the sense that in order to be apprehended, they utilize a set of relationships of which there are just as many as the dimensions forming them, not as predicates but as primary constituents. Experimentally, in the case of GM fish, we translate this by proposing to typologize legal and ethical considerations induced by multiple relations connected to this object. According to the type of relationship in question, the GM fish will not have the same status; it is a changing object that must be suitably apprehended.     

Ethical Discourse on the Use of Genetically Modified Crops: A Review of Academic Publications in the Fields of Ecology and Environmental Ethics

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.

GMOs and Global Justice: Applying Global Justice Theory to the Case of Genetically Modified Crops and Food

Proponents of using genetically modified (GM) crops and food in the developing world often claim that it is unjust not to use GMOs (genetically modified organisms) to alleviate hunger and malnutrition in developing countries. In reply, the critics of GMOs claim that while GMOs may be useful as a technological means to increase yields and crop quality, stable and efficient institutions are required in order to provide the benefits from GMO technology. In this debate, the GMO proponents tend to rely on a simple utilitarian type of calculus that highlights the benefits of GMOs to the poor, but that overlooks the complex institutional requirements necessary for GMO production. The critics, recognizing the importance of institutional conditions, focus primarily on the negative impacts of institutional deficiencies, thereby overlooking the basically Rawlsian claim that institutions per se may generate claims to justice. This article investigates how GMOs might generate claims to global justice and what type of justice is involved. The paper argues that the debate on GMOs and global justice can be categorized into three views, i.e., the cosmopolitan, the pluralist, and the sceptic. The cosmopolitan holds that GMOs can and should be used for alleviating global hunger, whereas the sceptic rejects this course of action. I will argue here for a moderately cosmopolitan approach, relying on the pluralist view of institutions and the need to exploit the benefits of GMOs. This argument rests on the premise that global cooperation on GMO production provides the relevant basis for assessing the use of GMOs by the standard of global distributive justice.
