Age dependency of high-affinity ouabain receptors and their magnetosensitivity

Age dependency of [³H]-ouabain binding, ⁴⁵Ca²⁺ eflux and its magnetosensitivity in rats’ brain cortex and heart muscle tissues were studied. Curves of dose-dependent [³H]-ouabain binding consisted of three components with different affinities (10⁻⁷–10⁻⁴ M (α₁); 10⁻⁹–10⁻⁷ M (α₂); and 10⁻¹¹–10⁻⁹ M (α₃)). These curves were also characterized by different dose-dependent kinetics. [³H]-ouabain binding with α₃ receptors in brain cortex and heart muscle tissues of young and adult animals had a dose-dependent character, while that in old ones had a dose-independent character. A 0.2 T static magnetic field (SMF) exposure had modulation effect on ouabain binding with α₁, α₂ and α₃ receptors in young rats, while in adult ones, only α₃ receptors were magnetosensitive. In old animals, SMF exposure had no significant effect on ouabain binding with α₃ receptors in brain cortex, while in heart muscle, it had inhibitory effect on it. Age-dependent effect of ouabain impact on ⁴⁵Ca²⁺ efflux showed that all concentrations of ouabain lead to inhibitory effect in young animals’ brain cortex and heart muscle (with the exception of 10⁻¹⁰ and 10⁻⁶ M), while in old ones, it had activation effect as compared with data received without ouabain. SMF exposure in young animals had activation effect on ⁴⁵Ca²⁺ efflux from brain cortex and heart muscle in data without ouabain, and in old rats, ⁴⁵Ca²⁺ efflux from brain cortex was magnetic insensitive. In old animals, SMF increased ⁴⁵Ca²⁺ efflux even after extra low concentration of ouabain. It is suggested that α₃ receptors having a crucial role in the regulation of Na⁺/Ca²⁺ exchange serve as age-dependent magnetosensors of excitable cells.     

A Pluralist–Expressivist Critique of the Pet Trade

Elizabeth Anderson’s “pluralist–expressivist” value theory, an alternative to the understanding of value and rationality underlying the “rational actor” model of human behavior, provides rich resources for addressing questions of environmental and animal ethics. It is particularly well-suited to help us think about the ethics of commodification, as I demonstrate in this critique of the pet trade. I argue that Anderson’s approach identifies the proper grounds for criticizing the commodification of animals, and directs our attention to the importance of maintaining social practices and institutions that respect the social meanings of animals. Her theory alone, however, does not adequately address the role of the state in this project. Drawing on social contract theory to fill this gap, I conclude that the state’s role in regulating the pet trade should be limited to ensuring the welfare of animals in the stream of commerce, not prohibiting their mass marketing altogether.     

Exponential Growth, Animal Welfare, Environmental and Food Safety Impact: The Case of China’s Livestock Production

Developmental states are criticized for rapid “industrialization without enlightenment.” In the last 30 years, China’s breathtaking growth has been achieved at a high environmental and food safety cost. This article, utilizing a recent survey of China’s livestock industry, illustrates the initiating role of China’s developmental state in the exponential expansion of the country’s livestock production. The enthusiastic response of the livestock industry to the many state policy incentives has made China the world’s biggest animal farming nation. Shortage of meat and dairy supply is history. Yet, the Chinese government is facing new challenges of no less a threat to political stability. Production intensification has created a welfare crisis impacting the world’s biggest number of farm animals. The resulting food safety incidents are affecting consumer confidence and health. Untreated waste contributes to the nation’s environmental degradation. Developmental states may have a proud record of growth in the initial stage of industrialization. Their prospects for sustained development have long been questioned. China has come to an important juncture to march towards a sustained development.     

Deep Ethology, Animal Rights, and the Great Ape/Animal Project: Resisting Speciesism and Expanding the Community of Equals

In this essay I argue that the evolutionary and comparative study of nonhuman animal (hereafter animal) cognition in a wide range of taxa by cognitive ethologists can readily inform discussions about animal protection and animal rights. However, while it is clear that there is a link between animal cognitive abilities and animal pain and suffering, I agree with Jeremy Bentham who claimed long ago the real question does not deal with whether individuals can think or reason but rather with whether or not individuals can suffer. One of my major goals will be to make the case that the time has come to expand. The Great Ape Project (GAP) to The Great Ape/Animal Project (GA/AP) and to take seriously the moral status and rights of all animals by presupposing that all individuals should be admitted into the Community of Equals. I also argue that individuals count and that it is essential to avoid being speciesist cognitivists; it really doesn't matter whether ‘dogs ape’ or whether ‘apes dog’ when taking into account the worlds of different individual animals. Narrow-minded primatocentrism and speciesism must be resisted in our studies of animal cognition and animal protection and rights. Line-drawing into ‘lower’ and ‘higher’ species is a misleading speciesist practice that should be vigorously resisted because not only is line-drawing bad biology but also because it can have disastrous consequences for how animals are viewed and treated. Speciesist line-drawing also ignores within species individual differences. This revised version was published online in July 2006 with corrections to the Cover Date.     

Historical Analysis of SO<Subscript>2</Subscript> Pollution Control Policies in China

Coal is not only an important energy source in China but also a major source of air pollution. Because of this, China’s national sulfur dioxide (SO₂) emissions have been the highest in the world for many years, and since the 1990s, the territory of China’s south and southwest has become the third largest acid-rain-prone region in the world. In order to control SO₂ emissions, the Chinese government has formulated and promulgated a series of policies and regulations, but it faces great difficulties in putting them into practice. In this retrospective look at the history of SO₂ control in China, we found that Chinese SO₂ control policies have become increasingly strict and rigid. We also found that the environmental policies and regulations are more effective when central officials consistently give environmental protection top priority. Achieving China’s environmental goals, however, has been made difficult by China’s economic growth. Part of this is due to the practice of environmental protection appearing in the form of an ideological “campaign” or “storm” that lacks effective economic measures. More recently, better enforcement of environmental laws and regulations has been achieved by adding environmental quality to the performance assessment metrics for leaders at all levels. To continue making advances, China needs to reinforce the economic and environmental assessments for pollution control projects and work harder to integrate economic measures into environmental protection. Nonetheless, China has a long way to go before economic growth and environmental protection are balanced.     

Inspiring Respect for Animals Through the Law? Current Development in the Norwegian Animal Welfare Legislation

Over the last years, Norway has revised its animal welfare legislation. As of January 1, 2010, the Animal Protection Act of 1974 was replaced by a new Animal Welfare Act. This paper describes the developments in the normative structures from the old to the new act, as well as the main traits of the corresponding implementation and governance system. In the Animal Protection Act, the basic animal ethics principles were to avoid suffering, treat animals well, and consider their natural needs and instincts. In addition, a principle for balancing our duties towards animals with the needs and interests of humans was expressed by the formulation “unnecessary suffering.” These principles (only with slightly different formulations) are retained in the new act. The novelty of the new act is shown by its explicit intention to promote respect for animals and its recognition of animals’ intrinsic value. Whereas intrinsic value is only given a symbolic function, the notion of respect is intended to have practical consequences. One interpretation of respect for animals is taking the animal’s integrity—and not only welfare—into account. Another is to see the introduction of respect as a call to animal keepers to provide animals with welfare exceeding the minimum requirements. In several respects, the legal system now seems to leave more responsibility to the individual animal keeper—and to citizens in general. I argue that if the authorities really do want to promote respect for animals, they must at the same time initiate activities to achieve this. In my perspective the challenge is to provide adequate measures to achieve in practice the intended respect for animals expressed in the new act.     

Sewage treatment by vermifiltration with synchronous treatment of sludge by earthworms: a low-cost sustainable technology over conventional systems with potential for decentralization

Earthworms’ body works as a ‘biofilter’ and they have been found to remove the 5 days’ BOD (BOD₅) by over 90%, COD by 80–90%, total dissolved solids (TDS) by 90–92%, and the total suspended solids (TSS) by 90–95% from wastewater by the general mechanism of ‘ingestion’ and biodegradation of organic wastes, heavy metals, and solids from wastewater and also by their ‘absorption’ through body walls. Earthworms increase the hydraulic conductivity and natural aeration by granulating the clay particles. They also grind the silt and sand particles, increasing the total specific surface area, which enhances the ability to ‘adsorb’ the organics and inorganic from the wastewater. Intensification of soil processes and aeration by the earthworms enable the soil stabilization and filtration system to become effective and smaller in size. Suspended solids are trapped on top of the vermifilter and processed by earthworms and fed to the soil microbes immobilized in the vermifilter. There is no sludge formation in the process which requires additional expenditure on landfill disposal. This is also an odor-free process and the resulting vermifiltered water is clean and disinfected enough to be reused for farm irrigation and in parks and gardens G.

Overview of Contemporary Issues of Forest Research and Management in China

With 207 million ha of forest covering 22% of its land area, China ranks fifth in the world in forest area. Rapid economic growth, climate change, and forest disturbances pose new, complex challenges for forest research and management. Progress in meeting these challenges is relevant beyond China, because China’s forests represent 34% of Asia’s forests and 5% of the worlds’ forests. To provide a broader understanding of these management challenges and of research and policies that address them, we organized this special issue on contemporary forest research and management issues in China. At the national level, papers review major forest types and the evolution of sustainable forestry, the development of China’s forest-certification efforts, the establishment of a forest inventory system, and achievements and challenges in insect pest control in China. Papers focused on Northern China address historical, social, and political factors that have shaped the region’s forests; the use of forest landscape models to assess how forest management can achieve multiple objectives; and analysis and modeling of fuels and fire behavior. Papers addressing Central and South China describe the “Grain for Green” program, which converts low productivity cropland to grassland and woodland to address erosion and soil carbon sequestration; the potential effects of climate change on CO₂ efflux and soil respiration; and relationships between climate and net primary productivity. China shares many forest management and research issues with other countries, but in other cases China’s capacity to respond to forest management challenges is unique and bears watching by the rest of the world.     

Impact of industrial air pollutants on some biochemical parameters and yield in wheat and mustard plants

The present study was carried out to determine the impacts of SO₂, NO _x , SPM and RSPM, the most common air pollutants, generated mainly due to industries and vehicles, on some biochemical parameters and yield in wheat and mustard plants during 2006. The concentration of SO₂, NO _x , SPM and RSPM was determined at the polluted sites across the seasons, which ranged between 14.29–18.10, 20.81–22.43, 483.65–500.85 and 160.67–171.18 μg m⁻³, respectively. The wheat and mustard plants grown at polluted sites showed significant reduction in chlorophyll ‘a’, chlorophyll ‘b’, total chlorophyll, carotenoid, ascorbic acid, pH, relative water content and yield. The data were further analyzed using a two way ANOVA. It is concluded that the ambient air pollutants have a potential adverse impact on biochemical parameters, which further leads to a reduction in the yield of wheat and mustard crops.     

An assessment of agricultural sustainability indicators in Bangladesh: review and synthesis

The term ‘indicator’ is often vague and heterogeneous, and its dynamic characteristics make it highly variable over time and space. Based on reviews and synthesis, this study visualizes phenomena and highlights the trend of indicator selection criteria, development methods, validation evaluation strategies for improvement. In contextualization of the intensification of agriculture and climate change, we proposed a set of indicators for assessing agricultural sustainability in Bangladesh based on theoretically proposed and practically applied indicators by researchers. Also, this article raises several issues of indicator system development and presents a summary after due consideration. Finally, we underline multi-stakeholders’ participation in agricultural sustainability assessment.     

Genetic engineering and the dignity of creatures

The Swiss expert report suggests that the inherent dignity of a living being be identified with its inherent value. But the phrase “inherent value of a living being” seems to connote two concepts of inherent value. One has a morally obligating character but is counterintuitive because of its egalitarianism. The other is one of non-moral value. It is more compatible with considered intuitions but insufficient for substantiating the expert report’s claim that human beings have moral duties towards animals and plants. The paper discusses these concepts. Consideration is then given to the problem of how discursive support can be generated for the expert report’s claim that human beings have the moral duty to abstain from impairing those functions and abilities of a non-human being that members of its species as a rule can practice.     

A Simple Value-Distinction Approach Aids Transparency in Farm Animal Welfare Debate

Public debate on acceptable farm animal husbandry suffers from a confusion of tongues. To clarify positions of various stakeholder groups in their joint search for acceptable solutions, the concept of animal welfare was split up into three notions: no suffering, respect for intrinsic value, and non-appalling appearance of animals. This strategy was based on the hypothesis that multi-stakeholder solutions should be based on shared values rather than on compromises. The usefulness of such an artificial value distinction strategy was tested in a small series of experiments. The results demonstrate that the chosen concept to distinguish between values is effective in a stakeholder context. Farmers’ views on doing good to animals appeared to be largely based on their value to prevent suffering and predominantly focused on the provision of regular care. Their priority for this value is clearly shared with other stakeholders, providing a basis for joint solutions. The concept of intrinsic value does not play a discernable role in farmers’ considerations. Based on the varying views on welfare, it can be inferred that there is a gradual rather than a principal difference between government legislation and farmers’ values, whereas public perception and acceptance of farm practices remains complicated. Distinction between value groups and focusing on a selected notion (such as no suffering) proved to be effective in bringing representatives of stakeholder groups together, but is unlikely to bridge the emotional gap between commercial farm practices and public ideals.     

The Relationship Between Workers and Animals in the Pork Industry: A Shared Suffering

Animal production, especially pork production, is facing growing international criticism. The greatest concerns relate to the environment, the animals’ living conditions, and the occupational diseases. But human and animal conditions are rarely considered together. Yet the living conditions at work and the emotional bond that inevitably forms bring the farm workers and the animals to live very close, which leads to shared suffering. Suffering does spread from animals to human beings and can cause workers physical, mental, and also moral suffering, which is all the more harmful due to the fact that it is concealed. The conceptual tools used to conceal suffering (“animal welfare,” stress, pain) suggest that the industrial system can be improved, whereas for farmers it is by definition incompatible with animal husbandry.     

The ethics and politics of the caged layer hen debate in New Zealand

Changes in attitudes toward animal welfare, with a greater emphasis on the importance of allowing animals to express normal patterns of behavior has led to an examination of the practice of keeping hens in battery cages. There is widespread scientific consensus that the conditions of confinement and the barren nature of battery cages severely restrict hens’ behavioral repertoire, and are thus detrimental to their welfare. The New Zealand Animal Welfare Act 1999, stipulates that animals must have “the opportunity to display normal patterns of behaviour.” In spite of this provision, the New Zealand government has not acted in phasing out battery cages, arguing instead that there is insufficient evidence that welfare will be improved by a phase-out. There is evidence of strong industry pressure on the government, and the use of tactics common in policy considerations where changes are resisted by powerful interests. It is important that policy processes are better managed so that welfare changes are based on both public preferences and scientific knowledge, and ways of doing this are discussed.     

A Defense of Animal Rights

I argue that animals have rights in the sense of having valid claims, which might turn out to be actual rights as society advances and new scientific-technological developments facilitate finding alternative ways of satisfying our vital interests without using animals. Animals have a right to life, to liberty in the sense of freedom of movement and communication, to subsistence, to relief from suffering, and to security against attacks on their physical existence. Animals’ interest in living, freedom, subsistence, and security are of vital importance to them, and they do not belong to us; they are not the things we have already possessed by virtue of our own nature.     

Converting wasteland into wonderland by earthworms—a low-cost nature’s technology for soil remediation: a case study of vermiremediation of PAHs contaminated soil

Earthworms in general are tolerant to many chemical contaminants including heavy metals and organic pollutants in soil and can bio-accumulate them in their tissues. Earthworms species like Eisenia fetida, Eisenia tetraedra, Lumbricus terrestris, Lumbricus rubellus and Allobophora chlorotica have been found to remove heavy metals (Cd, Pb, Cu, Hg, etc.) pesticides and lipophilic organic micropollutants like the polycyclic aromatic hydrocarbons (PAH) from the soil. They ‘absorb’ the dissolved chemicals through the moist ‘body wall’ in the interstitial water and also ‘ingest’ by mouth while the soil passes through the gut. They either ‘bio-transform’ or ‘biodegrade’ the chemical contaminants rendering them harmless in their bodies. Meanwhile the quality of the soil is improved significantly in terms of physical, chemical and biological properties as the worms thoroughly upturn and disperse the soil, ingest large volumes of soil and excrete nutritive materials (NKP and micronutrients) in the form of ‘vermicasts’ along with millions of beneficial soil microbes including nitrogen fixers.     

Phytocapping: An alternative technique to reduce leachate and methane generation from municipal landfills

Avoiding percolation of water into refuse is the key function of landfill covers. ‘Phytocapping’ has been considered as an effective, economical and environment-friendly technique for landfill remediation. In this technique, trees are established on a layer of soil cap placed over the refuse. Soil cover acts as a ‘storage’ and trees act as ‘bio-pump and filters’. For effective functioning of this technique, it is critical that an ‘optimum’ depth of soil is placed over the refuse, and ‘suitable’ plant species are used as plant cover. Preliminary results of a phytocapping trial (using 21 tree species and two depths of soil layers) show that the established trees can remove more water than that received via rainfall and rainfall interception can reduce up to 20% of the rain reaching the soil in a 1.5 year old plantation. The study is also trialling an US numeric model ‘STOMP’ (Subsurface Transport over Multiple Phases), to calculate daily water balance, to identify suitable plant species and to optimise thickness of the soil cover to be used in phytocapping.     

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.     

Harm to Others: The Social Cost of Antibiotics in Agriculture

It has become increasingly clear that the use of antibiotics in conventionally raised livestock contributes to the emergence of antibiotic-resistant bacteria. In this paper, I argue that the harm principle of classical liberalism should guide agricultural policy in general, and the regulation of antibiotics in livestock in particular. After developing an interpretation of the harm principle, and framing the choice to produce and consume animals treated with antibiotics as a classic prisoner’s dilemma, I consider some policy responses to the problem, including a ban on the non-therapeutic use of antibiotics.     

Revolution or inch-by-inch? Campaign approaches on climate change by environmental groups

Climate change is a significant environmental, social and environmental problem that has been identified by scientists in consensus internationally. The Australian Government’s response is considered by environmental non-government organisations (NGOs) to be inadequate. NGOs are ‘change agents’ of society, and in this role they are agitating to influence political decision-making on climate change response. This paper outlines the campaign strategies being used by Australian NGOs to attract public and political attention to the issue of climate change. Using seven NGOs as case studies, the archival materials of these organisations were accessed and analysed. Current academic and other literature also was used to reflect on their effectiveness. Four campaign themes and, within these, fifteen activities were identified. The results indicate that the notion of whether NGOs are undertaking an ‘revolutionary’ or ‘incremental’ approach, or any other narrow strategic approach put forward by various scholars is too simple for analysing campaigns: none of the NGOs appear to intentionally favour one type of strategy. The question raised by this finding is whether the NGOs’ current ‘multi-strategic’ approach is effective. This research contributes to filling the information gap with regard to NGO campaign strategies on environmental issues, and highlights the need for further research.
