Thus far, the moral debateconcerning genetically modified foods (GMF) hasfocused on extrinsic consequentialist questionsabout the health effects, environmental impacts,and economic benefits of such foods. Thisextrinsic approach to the morality of GMF isdependent on unsubstantiated empirical claimsand fails to account for the intrinsic moralvalue of food and food choice and theirconnection to the agent's concept of the goodlife. I develop a set of objections to GMFgrounded in the concept of integrity andmaintain that food and food choice can beintimately connected to the agent's personalintegrity. I argue that due to the constitutionof GMF and the manner in which they areproduced, such foods are incompatible with thefundamental values and integrity of certainindividual moral agents or groups. I identifythree types of integrity that are threatened byGMF: religious, consumer, and integrity basedon certain other moral or metaphysical grounds.I maintain that these types of integrity aresufficiently important to provide justificationfor political and societal actions to protectthe interests of those affected. I conclude byproposing specific steps for handling GMFconsistent with the moral principles ofinformed consent, non-maleficence, and respectfor the integrity of all members of society.They include mandatory labeling of GMF, theimplementation of a system for control andregulations concerning such foods, andguaranteed provision of conventional foods. 相似文献

The paper explores the potential political impact of global climate change and, more generally, of natural disaster. Because
the affluent West has largely tamed the natural and the social domains, popular clamor for government to anticipate, prevent,
and redress disaster increases. I delineate several consequences of the new politics of disaster. 相似文献

This paper discusses the relationship of new information and communication technologies (ICTs) and sustainable development. It deconstructs popular myths about a sustainable information society. One myth is that telework has reduced the need to travel and hence environmental pollution. The reality is that teleworkers make up only a small share of the total workforce, telework can generate new social relationships and hence the need for more travelling, work-related travel produces only a small amount of the total carbon dioxide emissions, and that the total distance travelled per employee is constantly rising. Another myth is that information economy is weightless and dematerialized which reduces environmental impacts. The energy and resource intensities of the ICT sector are indeed lower than the one of the total economy. The ICT sector also emits less CO2 than the total economy. But the ICT sector constitutes only a small portion of the total value added and fossil fuel combustion is still the dominant activity of modern industrial economies. Some stakeholders argue that virtual products allow resource, energy, and transport savings. But burning digital music on compact discs and DVDs, printing digital articles and books, etc. results in rebound effects that cause new material and energy impacts, computers have a low life span of 2–3 years, reusable and upgradeable computers and computer equipment are hardly used and might not be as profitable as non-reusable ones, computers are consuming much energy. Alternatives such as energy consumption labels on ICTs and green ICTs that consume less energy contradict dominant economic interests. A sustainable information society is a society that makes use of ICTs and knowledge for fostering a good life for all human beings of current and future generations by strengthening biological diversity, technological usability, economic wealth for all, political participation of all, and cultural wisdom. Achieving a sustainable information society costs, it demands a conscious reduction of profits by not investing in the future of capital, but the future of humans, society, and nature. 相似文献

We need to ensure the sustainable management of advanced materials, such as purified silicon, that contribute to a low-carbon
society. Because a drastic increase in the demand for photovoltaic (PV) systems is tightening the supply of silicon for PV
cells, the sustainability of silicon feedstock needs to be explored. For this purpose, a material flow analysis of silicon
in Japan from 1996 to 2006 is presented in this paper. Our analysis finds that rapid growth in demand for polycrystalline
silicon (pc-silicon) and single crystalline silicon (sc-silicon) has changed the structure of the purified silicon supply.
The strong demand for purified silicon for solar cells is responsible for this change. While off-grade silicon obtained as
a by-product of electronic-grade silicon (EG-Si) covered the demand for solar sells before 2000, pc-silicon is currently produced
independently for solar cells via an energy-intensive process. Analysis of the resource effective-use index (REI), which indicates
how effectively purified silicon is used, shows progress in the effective use of pc- and sc-silicon. REI analysis indicates
that the effective use of pc-silicon is reaching a maximum, while the effective use of sc-silicon is advancing, with a corresponding
increase in price. To ensure a sustainable supply of silicon feedstock, this paper proposes four solutions: (1) production
of solar-grade pc-silicon by a less costly and less energy-consuming method; (2) reduction in the amount of crystalline silicon
per watt in solar cells; (3) acceleration of the development and deployment of other solar cell types; and (4) reuse and recycling
of solar cells in the future. 相似文献
