Ethics and the Genetic Engineering of Food Animals

Biotechnology applied to traditional foodanimals raises ethical issues in three distinctcategories. First are a series of issues that arise inthe transformation of pigs, sheep, cattle and otherdomesticated farm animals for purposes that deviatesubstantially from food production, including forxenotransplantation or production of pharmaceuticals.Ethical analysis of these issues must draw upon theresources of medical ethics; categorizing them asagricultural biotechnologies is misleading. The secondseries of issues relate to animal welfare. Althoughone can stipulate a number of different philosophicalfoundations for the ethical assessment of welfare,most either converge on Bernard Rollins principle ofwelfare conservation (Rollin, 1995), or devolve intodebates over the ethical significance of animaltelos or species integrity. The principle of welfareconservation prohibits disfunctional geneticengineering of food animals, but would permit alteringanimals biological functions, especially when (as inmaking animals less susceptable to pain or suffering)do so improves an individual animals well being.Objections to precisely this last form of geneticengineering stress telos or species integrity asconstraints on modification of animals, and thisrepresents the third class of ethical issues. Most whohave formulated such arguments have failed to developcoherent positions, but the notion of species being,derived from the 19th century German tradition,presents a promising way to analyze the basis forresisting the transformation of animal natures.     

On the moral acceptability of killing animals

According to a rights view it is acceptable to kill animals if they are innocent threats or shields or are in a lifeboat situation. However, according to advocates of such a view, our practices of killing animals for food or scientific research may be morally unacceptable. In this paper we argue that, even if we grant the basic assumptions of a rights view, a good deal of killing of animals for food and scientific research continues to be morally acceptable.     

Arsenic levels in the marine ecosystem off the Kuwait coast, Arabian Gulf

Arsenic levels in seawater, microplankton (diatoms and dinoflagellates), shrimp (Penaeus semisulcatus), mollusc (Cerithium scabridum) and five types of fish (Maid, Nakroor, Nuwaiby, Suboor and Sheim) in five sampling stations (I–V) off the Kuwait coast were determined during the years 1995 to 1999. The maximum mean concentration of arsenic was observed in the order; the five fish (0.50–0.78 g g^–1)> mollusc (0.26 g g^–1)> shrimp (0.23 g g^–1)> particulate matter (0.03 g g^–1)> water and phytoplankton (0.02 g g^–1) from all the sites of the Kuwait coast. Station II possessed the maximum arsenic levels. In comparison with the arsenic levels in other parts of the globe, low arsenic levels were observed in most of the marine organisms off the Kuwait Coast. However, an increasing trend in arsenic concentrations was anticipated due to rapid local industrialization and on account of recent spills of arsenic compounds.     

Desertification Control and Management of Land Degradation in the Thar Desert of India

India has 2.34 million km² of hot desert called Thar located in the north-western part of Rajasthan between latitudes 23°3 and 30°12 North and longitudes 63°30 and 70°18 East. The Indian desert is spreading annually over 12000 ha of productive land degrading it and slowly advancing towards the national capital New Delhi at the rate of 0.5 km per year. The Indian desert is characterised by huge shifting sand dunes; high wind speed; scarce rainfall; and intense solar radiation. Tremendous efforts have been made since the 1960s to arrest desertification and for ecological restoration of the Thar desert. An Ambitious afforestation programme including stabilisation of shifting sand dunes and creation of micro-climates through tree-screens and shelter-belt plantation was launched by the forest department of Rajasthan. A huge canal, 649 km long was also introduced to the Thar desert for ecological restoration.     

Crisis,argument, and agriculture

Scholarly critics such as Wendell Berry, as well as the popular media, frequently refer to problems associated with agriculture as the agricultural crisis or the farm crisis. Despite the identification of a problem or problems as symptomatic of this crisis, scant attention is paid to why the situation is a social crisis as opposed to a problem, tragedy, trend, or simple change in the structure of agriculture. This paper analyzes the use of social crisis as applied to the state of modern agriculture and, by extension, other crises such as those in legitimation and morality. It concludes that, although important social values associated with farming as a way of life may be in danger of being lost, the crisis we may be facing with respect to agriculture is more properly understood as a sociopolitical crisis that has broader implications than simply the loss of farms or traditional farming values. Indeed, what is in danger of being lost is our ability to affect a secure and sustainable political-economic system.     

A utopian perspective on ecology and development

Summary Effective communication concerning environmental issues can take a variety of forms. The following essay is offered as a metalogue, a piece of writing in which the writing itself illustrates the principles developed in the writing.International readers will be helped if they know that Jack Armstrong and Sergeant Preston are heroes of moralizing (and often jingoistic) radio dramas popular among children in the United States during the War years and that the Tom Mix Holster Set and the A-bomb Ring were premiums offered to children in boxes of cold cereal in the period after the War. These trivia illustrate the kinds of societal messages directed toward the generation of Americans who presumably will be running the country during the 1980s.The authors are a professor of Psychology and Ethology and a graduate student in International Development. Both attended Harvard University in the late 1950s and the University of California, Berkeley, in the early 1960s. Their autobiographical reflections have something to say about the motivation underlying the environmental movement and where these motivations are likely to lead in the near future.     

Biosphere reserves in Germany: A contribution to support sustainable development

Summary Biosphere reserves are protected areas of representative environments internationally recognised for their value for conservation and for their ability to provide the scientific knowledge, skills and human values to support sustainable development. Biosphere reserves — as a part of the UNESCO programme Man and the Biosphere (MAB) — make up a world-wide network sharing research information on ecosystem conservation, management and development. They include strictly protected core-areas — representative examples of natural or minimally disturbed ecosystems. Core areas are surrounded by buffer zones in which research, environmental education and training and recreation can take place. Buffer zones are, in turn, surrounded by transition areas, large open areas where the aim is to ensure rational development of the natural resources of the region. At present, twelve biosphere reserves are designated in Germany, covering in all an area of 11,589 km². The role of biosphere reserves to support sustainable development in Germany and Europe is discussed.Karl-Heinz Erdmann is a geographer and Deputy Secretary General at the Secretariat of the German National Committee for the UNESCO Programme on Man and Biosphere (MAB), Federal Agency for Nature Conservation. He is also a Committee Member of the Society for Man and Environment (GMU).     

Naturalness In Biological Conservation

Conservation scientists are arguing whether naturalness provides a reasonable imperative for conservation. To clarify this debate and the interpretation of the term natural, I analyze three management strategies – ecosystem preservation, ecosystem restoration, and ecosystem engineering – with respect to the naturalness of their outcomes. This analysis consists in two parts. First, the ambiguous term natural is defined in a variety of ways, including (1) naturalness as that which is part of nature, (2) naturalness as a contrast to artifactuality, (3) naturalness as an historical independence from human actions, and (4) naturalness as possession of certain properties. After that, I analyze the different conceptions with respect to their implications for the three management strategies. The main conclusion is that there exists no single conception of naturalness that could distinguish between the outcomes of the three management methods. Therefore, as long as the outcomes of the different methods are regarded as being of a different value in conservation, we should either abandon the idea of naturalness as the guiding concept in conservation or use the term natural only in the ways that take both its historical and feature dependent meanings into consideration.     

Integrating Bioassessment and Ecological Risk Assessment: An Approach to Developing Numerical Water-Quality Criteria

Bioassessment is used worldwide to monitor aquatic health but is infrequently used with risk-assessment objectives, such as supporting the development of defensible, numerical water-quality criteria. To this end, we present a generalized approach for detecting potential ecological thresholds using assemblage-level attributes and a multimetric index (Index of Biological Integrity—IBI) as endpoints in response to numerical changes in water quality. To illustrate the approach, we used existing macroinvertebrate and surface-water total phosphorus (TP) datasets from an observed P gradient and a P-dosing experiment in wetlands of the south Florida coastal plain nutrient ecoregion. Ten assemblage attributes were identified as potential metrics using the observational data, and five were validated in the experiment. These five core metrics were subjected individually and as an aggregated Nutrient–IBI to nonparametric changepoint analysis (nCPA) to estimate cumulative probabilities of a threshold response to TP. Threshold responses were evident for all metrics and the IBI, and were repeatable through time. Results from the observed gradient indicated that a threshold was 50% probable between 12.6 and 19.4 g/L TP for individual metrics and 14.8 g/L TP for the IBI. Results from the P-dosing experiment revealed 50% probability of a response between 11.2 and 13.0 g/L TP for the metrics and 12.3 g/L TP for the IBI. Uncertainty analysis indicated a low (typically 5%) probability that an IBI threshold occurred at 10 g/L TP, while there was 95% certainty that the threshold was 17 g/L TP. The weight-of-evidence produced from these analyses implies that a TP concentration > 12–15 g/L is likely to cause degradation of macroinvertebrate assemblage structure and function, a reflection of biological integrity, in the study area. This finding may assist in the development of a numerical water-quality criterion for TP in this ecoregion, and illustrates the utility of bioassessment to environmental decision-making.     

Risk-taking and environmental perception

This paper investigates the relationship between pupils' environmental perception (in terms of preservation and utilisation of nature) and personality (in terms of risk-taking). 713 secondary school pupils in Switzerland were investigated. Environmental perception was assessed via three factors: Preservation, Utilisation of Nature and Consideration for Conservation. Risk-taking was evaluated via six factors: Positive Risking, Ambivalence, Thrill in Gambling, Ineffective Control, Effective Control, and Anger Reaction. Analysis of the correlation matrix between Risk-taking and Environmental perception revealed three profiles (types): the high scorer on Preservation is the controlled and cautious gambler. The Utiliser (anthropocentric) profile is essentially a mirror image of the first: the Utiliser does not enjoy unpredictable risks, reacts with anger when risks fail and has little control over his/her own risk-taking behaviour. The Consideration for Conservation (ecocentric) profile assumes a position between these two profiles.     

The limits of technological optimism

Summary Technological optimism is the doctrine that a growing number of technological improvements in such areas as food production, environmental quality and energy will sustain life as human population soars. It evolved as a response to the Malthusian study The Limits to Growth (The Club of Rome, 1972). Like population biologist Paul Ehrlich, Professor James Krier of the University of Michigan Law School believes that the technological optimists may be wrong. Krier describes how the marginal costs of pollution control increasingly rise. He faults biologist Barry Commoner for neglecting population growth as the cause of pollution and positing the postwar technological transition as its cause. He argues that population growth forced this transition as science searched for substitutes for dwindling resources. Krier criticises as an article of faith the technological optimists' belief that S-curve patterns of technological advance will always arrive in response to the J-curve of exponential population growth. He thinks that the technological optimists may be deluding humanity by predicting the continual emergence of technological breakthroughs at ever-increasing rates. He favours growth policies that would allow humanity to ease into a steady state of resource use and minimise the maximum cost, which would be a global crash after technological innovation fails. Krier laments that modern technolgy can worsen pollution and invites problems of latency, irreversibility, zero-infinity risk and remoteness. He thinks that approapriate technologies which have failed economically may fail politically because the political process has been captured by opposing interests. Krier urges that the population crisis should be adressed insteadAndrew D. Basiago is a graduate of UCLA and Northwestern School of Law's environmental law programme.

Options and limitations in fisheries management

Conclusion As a final thought, I want to conclude with the cliche that a problem recognized is half solved. Certainly, I cannot be accused of laying out a solution to solving the major fisheries management problems, but it is hoped that the problems managers face are now clearer. The complexity of fisheries assystems to be managed is clear to even the most casual observer. The second point, a broad theory of fisheries management, should provide a framework to categorize all of the disjointed activities that we associate with management of our fisheries resources.     

A proposed formal structure for assessing bear-human encounters

A formal model for the interaction of bear and hiker populations in national parks is developed. A number of alternative interactive scenarios are identified and some specific cases explored in detail. Some examples of the insights to be gained by the use of such a formal structure by park managers charged with the dual mandate of preservation of fauna and provision of safe recreational opportunities are presented. The entire problem is then discussed within the context of the more general tragedy of the commons problem.     

A course in Environmental Planning and Management

Summary This paper describes a 13-weeks, third-year course in Environmental Planning and Management developed and taught by the authors. Initiated in 1969, the course consists of a mix of lectures, seminars, workshop/laboratory sessions and field-based projects. The objectives of the course are for students: to become aware of the need for, and the complexities of, environmental management; to be able to criticise constructively work done by environmental agencies and consultants, managers and decision makers; and to learn and apply some of the methods and techniques used in environmental management.Topics covered by the current syllabus are: concepts of resource and environment; constitutional aspects; international law and the environment; Australian and Canadian environmental legislation and agencies; human manipulation of ecosystems; energy subsidies; modification of biogeochemical cycles; population dynamics and cropping; fisheries; national parks and reserves—policies in different countries; international heritage areas; environmental assessment (including impact assessment, land evaluation, land capability and land suitability assessment); and regional, integrated land-use and environmental planning and management. Techniques taught include: field surveys and interviewing; laboratory analysis of selected water quality, sediment and soil parameters including nutrient concentrations, heavy metal and pesticide residues; and for some students, applications of geographic information systems (GIS) technology following preceding GIS courses.A major problem is selecting the most appropriate mix between the social and natural sciences—appropriate, first in terms of students' heterogeneous skills and backgrounds, and second, in terms of understanding the causes of environmental problems and issues, and devising practicable solutions.     

The object of environmental ethics

Since the term environmental ethics began to be used a generation ago, it has covered many different kinds of environmental notions, problems, ethical systems, and forms of behavior. A variety of cases are presented and examined under two terms,environmental ethics andecological morality, in an effort to illustrate different kinds of ethical objectives. In order to understand the connections between various strands of environmental ethics, personal and social values and subcultural norms of environmental ethics are examined under Christopher Stone's concept of moral pluralism. G. J. Warnock's notion of the general object of morality is proposed to integrate the variegated purposes of environmental ethics.     

Investment in human capital in Africa

Summary The author analyses the problems currently faced by the African continent, recognises six factors which he believes are important in influencing the analysis, and argues that the only secure, renewable asset any country or continent has, is its people. He maintains that people development, rather than the classical economic forms of encouraging development, offers Africa a viable way forward. He then identifies a number of specific issues within such a strategy of investment in human capital.Brian Walker is the President of the International Institute for Environment and Development (IIED), and this address was given at the inaugural meeting of the International Year of Shelter for the Homeless, in London, on 18th April, 1985.

The Colorado,USA, Joint Review Process: an initial evaluation of its success as a permit reform by key participants

Colorado, USA, developed the Joint Review Process (CJRP) in 1978 to coordinate the application and review of permits required for major development projects. Since then, the state has used the process on over 20 projects. This study examined whether the CJRP has achieved its primary goals—enhanced coordination of agencies, enhanced public participation, and strengthened communication between agencies and project sponsors— and several related secondary goals. The success of the process was measured through a survey of 54 key people who had been directly involved with the process. Those surveyed included federal and state agency staff, local agency managers, corporate officers, private consultants, and environmental leaders. All groups, with one exception, agreed that the process achieved its primary goals and that it should be retained. Environmental leaders were neutral about whether the process enhanced public participation and about retaining the process. The report concludes with a review of recommended improvements to and applications of the CJRP.     

Toxicity and uptake of mercurials in a cyanobacterium

Nostoc calcicola cells exposed to mercuric chloride (0.05–0.25 M), methyl mercuric chloride (0.05–0.15 M) and the fungicide ceresan (phenyl mercuric acetate; 0.05–0.20 M) showed sensitivity in the sequence: methyl mercury3) over phenyl mercuric acetate (0.51×10³); inorganic mercury occupied the intermediate position with a bioconcentration factor of 1.32×10³. The data infer that larger molecules of organomercurials may not be taken up by cells at the rate and extent comparable to the smaller species.     

Nature Quality in Organic Farming: A Conceptual Analysis of Considerations and Criteria in A European Context

Nature quality in relation to farming is a complex field. It involves different traditions and interests, different views of what nature is, and different ways of valuing nature. Furthermore there is a general lack of empirical data on many aspects of nature quality in the farmed landscape. In this paper we discuss nature quality from the perspective of organic farming, which has its own values and goals in relation to nature – the Ecologist View of Nature. This is in contrast to the Culturist View characteristic of much conventional agriculture and the Naturalist View characteristic of the traditional biological approach to nature quality. This threefold distinction forms a framework for exploration of nature quality criteria in the farmed landscape. The traditional work on nature quality has mainly focused on biological interests based on a Naturalist View of Nature. In this paper we will explore how criteria for nature quality based on the Ecologist View can be developed and thereby feed into the ongoing discussion of the development of the organic farming practices. We suggest additional criteria for nature quality based on an Ecologist View of Nature: biodiversity, habitat diversity, extent and structure, functional integrity of habitats and agro-ecosystems, landscape integrity, accessibility, and experientiality. The larger set of Naturalist and Ecologist criteria can provide a wider and more balanced basis for developing nature quality indicators that are relevant in the farmed landscapes. This broader approach to nature quality is also expected to benefit the general societal discussions and decisions on farming and nature.
