An interdisciplinary book written by Métis scientist and activist Max Liboiron, Pollution is Colonialism shows how doing environmental research and activism is often premised on a colonial worldview even when practitioners are working towards benevolent goals. The book lays out key terms and a framework for understanding scientific research methods as ways of being in the world that can align with or against colonialism. Liboiron models an anti-colonial scientific practice aligned with Indigenous concepts of land, ethics, and relations, all (...) while taking up the project of Western science, dealing with issues of compromise and conflicting ideas of good relations.

Environmental pollution and climate change have been considered the main environmental challenges affecting the world’s ecosystem, including that of South Africa. They cause poverty, land degradation, and health hazards. One of the leading causes and contributing factors of environmental pollution and climate change is carbon emissions into the atmosphere. As a way to curb these emissions, Carbon tax policy has been introduced in various countries, including South Africa. In 2019, a Carbon tax was introduced to assist South Africa (...) in delivering on the commitments made in the Paris Agreement in 2015. If the policy is effectively applied, it will raise revenues while reducing carbon dioxide emissions. Before and after introducing the Carbon tax policy in South Africa, there has been debate and discussion on its impact on the environment, economy, and society. Based on the debate and discussion, it has been observed that more attention is paid to the economic implications and benefits of the tax on South Africa than the ethical implications. Thus, this paper aims to contribute to the ongoing debate and discussion by ethically evaluating the Carbon tax policy in South Africa. (shrink)

Logical inferentialism claims that the meaning of the logical constants should be given, not model-theoretically, but by the rules of inference of a suitable calculus. It has been claimed that certain proof-theoretical systems, most particularly, labelled deductive systems for modal logic, are unsuitable, on the grounds that they are semantically polluted and suffer from an untoward intrusion of semantics into syntax. The charge is shown to be mistaken. It is argued on inferentialist grounds that labelled deductive systems are as syntactically (...) pure as any formal system in which the rules define the meanings of the logical constants. (shrink)

In this paper, I undertake a conceptual analysis of ordinary usages of the concepts of “litter” and “pollution.” If “litter” or “pollution” applies to space debris in its various contexts, then in dealing with space debris as an ethical concern, we may more neatly apply arguments for the wrongness of litter and pollution to these new contexts. After engaging in a conceptual analysis of “litter” and “pollution,” I consider whether these concepts apply to space debris, examining (...) three contexts: (1) surface debris on Moon and Mars, (2) intentionally crashing objects into gas giants, ice giants, and stars, and (3) the pressing issue of orbital space debris. I conclude by finding that neither “litter” nor “pollution” cleanly applies to any of these three contexts. (shrink)

This article compares the material pollution of life's elementary resources, i.e., water, soil, and air, with the semiotic pollution of the elementary resources of sign-processes, i.e., channel, sign-matter, and message; code, signifier, and signified; as well as context, sender, and recipient. It is claimed that semiotic pollution interferes with sign-processes as much as material pollution interferes with the fundamental processes of life; both types of pollution are similar in that they produce stress for human beings (...) in current societies. It is argued that semiotics is able to provide the conceptual tools necessary to develop policies that can reduce semiotic pollution. As is shown, however, additional research is required to operationalize and metricize generalized concepts of semiotic pollutionsuch as "channel-related", "semiosis-related", and "situation-related noise".

Human consumption of pharmaceuticals often leads to environmental release of residues via urine and faeces, creating environmental and public health risks. Policy responses must consider the normative question how responsibilities for managing such risks, and costs and burdens associated with that management, should be distributed between actors. Recently, the Polluter Pays Principle (PPP) has been advanced as rationale for such distribution. While recognizing some advantages of PPP, we highlight important ethical and practical limitations with applying it in this context: PPP (...) gives ambiguous and arbitrary guidance due to difficulties in identifying the salient polluter. Moreover, when PPP does identify responsible actors, these may be unable to avoid or mitigate their contribution to the pollution, only able to avoid/mitigate it at excessive cost to themselves or others, or excusably ignorant of contributing. These limitations motivate a hybrid framework where PPP, which emphasizes holding those causing large-scale problems accountable, is balanced by the Ability to Pay Principle (APP), which emphasizes efficiently managing such problems. In this framework, improving wastewater treatment and distributing associated financial costs across water consumers or taxpayers stand out as promising responses to pharmaceutical pollution from human use. However, sound policy depends on empirical considerations requiring further study. (shrink)

Just because one has the right to vote does not mean just any vote is right. Citizens should not vote badly. This duty to avoid voting badly is grounded in a general duty not to engage in collectively harmful activities when the personal cost of restraint is low. Good governance is a public good.

Many democratic theorists agree that we (...) shouldn’t vote badly, but that’s because they think we should vote well. This demands too much of citizens. (shrink)

After the United States Congress passed the Water Pollution Control Act of 1948, biologists played an increasingly significant role in scientific studies of water pollution. Biologists interacted with other experts, notably engineers, who managed the public agencies devoted to water pollution control. Although biologists were at first marginalized within these agencies, the situation began to change by the early 1960s. Biological data became an integral part of water pollution control. While changing societal values, stimulated by an (...) emerging ecological awareness, may explain broader shifts in expert opinion during the 1960s, this article explores how graphs changed experts’ perceptions of water pollution. Experts communicated with each other via reports, journal articles, and conference speeches. Those sources reveal that biologists began experimenting with new graphical methods to simplify the complex ecological data they collected from the field. Biologists, I argue, followed the engineers’ lead by developing graphical methods that were concise and quantitative. Their need to collaborate with engineers forced them to communicate, negotiate, and overcome conflicts and misunderstandings. By meeting engineers’ expectations and promoting the value of their data through images as much as words, biologists asserted their authority within water pollution control by the early 1960s.

This article traces an emergent tension in an interdisciplinary public health project called Weather Health and Air Pollution. The tension centered on two different kinds of data of air pollution: monitored and modeled data. Starting out with monitoring and modeling practices, the different ways in which they enacted air pollution are detailed. This multiplicity was problematic for the WHAP scientists, who were intent on working across disciplines, an initiative driven primarily by the epidemiologists who imbued the project (...) with meaning and value as the protagonists of “health.” To work collaboratively implies a stable, singular, and shared research object, however: one kind of data, one version of air pollution. In detailing two attempts by researchers to address the inadequacies of modeled and monitored data, this article explores the ways in which difference and multiplicity were negotiated and transformed. In doing so, this article suggests that it is the mobility and instability of data that are particularly fruitful for exploring the facilitation and enactment of new realities, while also making explicit the emergent problematics and partialities which inevitably result.

Focusing on the recent explosion in the use of bottled water, this article—originally written for my NASTS conference presentation—will examine the rhetoric used by the bottled water industry and home purification system providers to affect the public’s idea of clean, pure, dirty, and polluted water. Bottlers argue that the Food and Drug Administration (FDA) provides better regulation of bottled water than the Environmental Protection Agency (EPA) could ever do for tap water, though the EPA and the FDA use basically the (...) same set of guidelines. The EPA and FDA definitions in terms of concentrations of specific substances are very different from the ideas of muddy or “dirty” water. This article will examine the impact of the public’s perception of good drinking water and the perception that if it is off the shelf, it is cleaner and tastier. (shrink)

Air pollution is a current concern of people and government entities. Therefore, in urban scenarios, its monitoring and subsequent analysis is a remarkable and challenging issue due mainly to the variability of polluting-related factors. For this reason, the present work shows the development of a wireless sensor network that, through machine learning techniques, can be classified into three different types of environments: high pollution levels, medium pollution and no noticeable contamination into the Ibarra City. To achieve this (...) goal, signal smoothing stages, prototype selection, feature analysis and a comparison of classification algorithms are performed. As relevant results, there is a classification performance of 95% with a significant noisy data reduction. (shrink)

Dr Stockmann, the principal character in Henrik Ibsen's A Public Enemy, is a classic example of a whistle-blower who, upon detecting and disclosing a serious case of environmental pollution, quickly finds himself transformed from a public benefactor into a political outcast by those in power. If we submit the play to a 'second reading', however, it becomes clear that the ethical intricacies of whistle-blowing are interwoven with epistemological issues. Basically, the play is about the complex task of communicating scientific (...) (notably microbiological) data to lay audiences. This becomes even more apparent when we realise that Stockmann was a contemporary of real 'microbe hunters' such as Pasteur and Koch. The play's basic message is that epoch-making scientists (such as Pasteur and Koch) not only produced convincing and reliable data from a scientific point of view, but also acquired the skills and insights needed to enter into a dialogue with their cultural and societal environment.

This paper provides theoretical support for two historical principles for the allocation of remedial responsibility for paying the costs of pollution caused by humans. These remedial principles are based upon particular forms of backward-looking connection with the pollution in question. The suggestion is that we can have reasons to pay the costs of pollution when we are members of communities which were responsible for the original polluting acts in question and/or which have benefited from the polluting acts. (...) In seeking to provide support for backward-looking remedial duties, the paper aims to bolster understandings of the principle of Common but Differentiated Responsibility (CBDR) which place the primary burden of meeting the costs of pollution upon those communities which caused the pollution in the first place. Thus, in supporting the “beneficiary pays” principle in general, and the “polluter pays” principle in some cases, I challenge interpretations of CBDR which maintain that backward-looking principles are unfair, since they impose duties upon present day generations who were not themselves responsible for the polluting acts in question.

Using a sample of Chinese listed firms in polluting industries for the period of 2008–2010, we empirically investigate whether and how Buddhism, China’s most influential religion, affects corporate environmental responsibility (CER). In this study, we measure Buddhist variables as the number of Buddhist monasteries within a certain radius around Chinese listed firms’ registered addresses. In addition, we hand-collect corporate environmental disclosure scores based on the Global Reporting Initiative (GRI) sustainability reporting guidelines. Using hand-collected Buddhism data and corporate environmental disclosure scores, (...) we provide strong and robust evidence that Buddhism is significantly positively associated with CER. This finding is consistent with the following view: Buddhism can serve as social norms to evoke the consciousness of social responsibility, and thereof strengthen CER. Our findings also reveal that the positive association between Buddhism and CER is attenuated for firms with higher law enforcement index. The results are robust to various measures of Buddhism and a variety of sensitivity tests. (shrink)

This paper determines the acoustic properties of external wall building materials composition. Noise pollution is one of the main pollutants nowadays but it is not considered of great importance in the construction field, despite some studies showing that greater acoustic pollution is produced by buildings under construction. The study consists of analysing two different types of buildings equipped with a different type of external masonry composition in terms of building materials. The buildings are located at “21 Dhjetori” street, (...) Tirana, Albania. Furthermore, the case study area is treated as an area that consistently harvests noise. The impact of noise pollution on the existing building materials is going to be analyzed. Those milestones will provide information regarding the noise levels, a comparison of the actual level of noise production (outdoor and indoor areas), sound transmission, and sound diminution, as well as the implementation of acoustic materials in order to improve the quality of life of the inhabitants. The selected area has the highest norms of acoustic pollution in the city according to the studies implemented by Determination of acoustic properties of building materials is an important task gaining higher importance due to the demand for suitable construction materials, located in places with high levels of noise and places with heavy traffic, such as in urban areas. The aim of this paper is to display a comparative study of the actual noise levels generated by this area. It indicates the acoustic properties of the current building materials followed by a more suitable soundproof insulation. (shrink)

Racial environmental inequities, documented in research over the past ten years, have deep cultural sources in the connections between the concept of social pollution as it has operated in U.S. race relations and the pollution of minority communities, both of which are, in part, the expression of our dominant cultural ethic and project of mastering nature. The project of mastering nature requires thedisciplining of “human nature” in a context of social power in order to dominate “outward” or “external” (...) nature for the purposes of production and consumption. In disciplining human nature, our ethics and practices of work and gender have fostered the repression and projection of sensuality, widely construed, onto African-Americans in particular. This racial “other” has been historically segregated in our society through social pollution taboos. Social pollution practices, in turn, facilitate the disproportionate environmental pollution of minority communities by rendering such pollution, like the communities themselves, less visible and therefore less of a threat to white centers of power. This fit between social and environmental pollution is expressed in the notion of “appropriately polluted space.” Attempts to understand and correct racial environmental inequities will founder unless these deeper cultural connections are recognized and challenged. Moreover, attempts to redefine an environmentally benign “self” in the Americancontext require that the historical “other” of race be confronted and transcended. (shrink)

The Air Quality Index (AQI) shows the state of air pollution in a unique and more understandable way. This work aims to forecast the AQI in Algeciras (Spain) 8 hours in advance. The AQI is calculated indirectly through the predicted concentrations of five pollutants (O3, NO2, CO, SO2 and PM10) to achieve this goal. Artificial neural networks (ANNs), sequence-to-sequence long short-term memory networks (LSTMs) and a newly proposed method combing a rolling window with the latter (LSTMNA) are employed as (...) the forecasting techniques. Besides, two input approaches are evaluated: using only the data from the own time series of the pollutant in the first case or adding exogenous variables in the second one. Several window sizes are employed (24, 28 and 72 hours) with ANNs and LSTMNAs. Additionally, several feature ranking methods are applied in the exogenous approach to select the most relevant lagged variables to feed the models. Results show how the proposed exogenous approach increases the performance of the prediction models. Besides, the newly proposed method LSTMNA provides the best performances in most of the cases evaluated. Hence, it constitutes an exciting alternative to standard LSTMs and ANNs to predict pollutants concentrations and, consequently, the AQI. (shrink)

The polluter pays principle (PPP) has the form of a reparative principle. It holds that since some countries have historically contributed more to global warming than others, these countries have the follow-up responsibility now to do more to address climate change. Yet in the climate justice debate, PPP is often rejected for two reasons. First, so the objection goes, it wrongly burdens present-day individuals because the actions of their predecessors. This is the unfairness objection. The second objection is that early (...) polluters were not aware of the harm that they were doing, and so ought not to be held culpable. This is the objection from excusable ignorance. In this commentary, I defend PPP against these two objections. The aim of this short reflection is not to provide a full justification of PPP, or to respond to all objections that have been made against it. My more limited but, I hope, important goal is to show that PPP is neither immediately unfair (in making innocent parties pay) nor immediately unreasonable (in making excusably ignorant parties pay) as is commonly noted, and is therefore worthy of further consideration as a principle of climate justice.

The article examines the effect of cooking food in kitchens on the health of women, as women and children are at a greater risk to indoor air pollution (IAP). It is important to study the cooking practices and prevalent behaviours among African women to understand the magnitude of the danger they face. The study suggests that a decline in the combustion of solid fuels and the use of clean energy can improve health among women and children, as well as (...) sustainability goals. Proverbs 17:22 says, ‘A joyful heart is the health of the body, but a depressed spirit dries up the bones’. Bible verse Numbers 35:33–34 indicates, ‘You shall not pollute the land in which you live’. The cooking fuel analysis framework among rural women in Africa will guide forward the governments’ sustainability policies for communities to ensure healthy lives and promote well-being of women and children. Contribution: The article conducts a comprehensive analysis of the literature on African cooking practices. A combined search string is made with keywords. Thematic content analysis is conducted with NVivo (produced by QSR International). The article covers two themes, namely improved well-being and suggesting policies to combat climate change and its impacts. Policies and schemes at grassroots levels and better economic conditions in African countries can help to overcome challenges and change health-damaging cooking behaviours. The new advanced sustainability analysis framework has the potential to influence modern kitchen fuels and increase the adoption of new technologies in African villages. (shrink)

Libertarians often emphasize courts’ potential to alleviate pollution problems without the need for legislation and regulation. However, this chapter argues courts cannot completely replace these other tools. Because of the historical conditions in which pollution law develops, we should expect courts in industrial societies to initially develop legal standards that deliver limited protection against many common pollution threats. As societies grow wealthier and citizens begin favoring stricter defenses against pollution, courts honoring longstanding precedents will struggle to (...) keep pace with changing priorities. Because legislators and regulators are authorized to create and alter laws deliberately in a way judges are not, they can perform an essential function by updating legal standards amidst changing circumstances. Libertarianism stands the best chance of addressing the challenges pollution creates by allowing each branch of the liberal division of powers to perform its role, not by substituting the judiciary for all other branches.

There is yet one more proposed solution to the argument from evil which merits attention. Though it does have elements in common with other proposed solutions in that it postulates a justifying end to account for the existence of all evil, it is different in that evil is viewed as nothing more than a polluting by-product of the proper functioning of the laws of nature in their industrious manufacture of the summum bonum. The unimpeded functioning of the laws of nature (...) is seen as necessary for the production and creation of a justifying (indiscernible) end and evil or suffering is merely a foreseen but unfortunate by-product of this natural machinery. The place and function of evil in this solution is what is novel: it is not a greatness-making property, nor is it a punishment or warning from on high, nor is its usefulness an aesthetic or contrasting one, nor is it the result of free will. Evil is admitted as just plain evil; it itself plays no role to serve the valuable end, which is precipitated by the unimpeded operation of natural laws upon the universe. Evil here is seen to play the same role that pollution might: it is a foreseen and unfortunate consequence of the means used to produce the coveted final product. -/- Professor Clement Dore, in his book entitled Theism,[1] introduces this solution in which evil itself plays no role to serve an enormously valuable end, yet is necessitated by this end. However, in order for the theist to be in a position to defend Dore's claim, a viable interpretation of the justifying, indiscernible end, must be proposed. To assess the validity of Dore's schema, four apparently exhaustive interpretations of the justifying end will be presented. It will be argued here that each of these possible interpretations is, in one respect or another, inadequate. The result is that the concept of the justifying, indiscernible end and its relation to Dore's overall schema lacks lucidity. In addition, other problems with this solution will be discussed in order to show that severe flaws exist in the solution as a whole. (shrink)

Air pollution in China has been drawing considerable attention in recent years. The emergence of new energy vehicles provides hope to reduce air pollutant emission. However, consumers' recognition and acceptance of NEVs remain at the early stage. This research aims to explore how consumers' environmental concern influences their NEV purchase intention. Specifically, this research conducted an online survey and an experiment to address the following issues: how consumers' psychological distance toward air pollution influences their purchase intention for NEVs, (...) and does their risk perception of the consequences of air pollution mediate this influence; whether consumers' perceived price level of NEVs plays a moderating role in the relationship between risk perception and purchase intention; and whether the construal level of stimulus can be manipulated to influence consumers' PD toward air pollution to increase their purchase intention for NEVs. The results of study 1, based on a total of 293 valid samples, show that consumers' PD toward air pollution significantly affects their purchase intention for NEVs, and risk perception of the consequences of air pollution plays a considerable mediating role. Meanwhile, consumers' perceived price level of NEVs has a significant negative moderating effect on the relationship between risk perception and purchase intention. The results of study 2, based on an online experiment, show that the construal level of stimulus can influence consumers' PD toward air pollution, which in turn affects their purchase intention for NEVs. The findings of this research have implications for businesses' promotional strategies and governments' policies. For instance, low-construal-level promotional materials can be developed to arouse consumers' environmental concern, thereby facilitating their eco-friendly consumption behavior. Governmental financial assistance and other policies can also increase consumers' willingness to purchase NEVs. (shrink)

To a large extent liability for ICT perils is still a grey area, even though an increasing number of information security researchers adopt economic approaches to highlight market mechanisms and externalities.

What is needed is a better understanding of (...) the consequences of externalities from ICT perils. This would benefit customers and increase trust in ICT products and services which in turn may even increase suppliers' profit margin; customers would be prepared to buy more services and products if contracts and service level agreements would accept more liability.

Lead (Pb) contamination of the environment is an important human health problem. Children are vulnerable to Pb toxicity; it causes damage to the central nervous system and, in some extreme cases, can cause death. Lead is widespread, especially in the urban environment, and is present in the atmosphere, soil, water and food. Pb tends to accumulate in surface soil because of its low solubility, mobility, and relative freedom from microbial degradation of this element in the soil. Lead is present in (...) soil as a result to weathering and other pedogenic processes acting on the soil parent material; or from pollution arising caused by the anthropogenic activities; such as mining, smelting and waste disposal; or through the adoption of the unsafe and unethical agricultural practices such as using of sewage sludge, and waste water in production of vegetable crops or cultivation of vegetables near highways and industry regions. Lead concentrations are generally higher in the leafy vegetables than the other vegetables. Factors affecting lead uptake included its concentration in the soil, soil pH, soil type, organic matter content, plant species, and unsafe agriculture practices. Generally, as Pb concentration increased; dry matter yields of roots, stems and leaves as well as total yield decreased. The mechanism of growth inhibition by lead involve: a decrease in number of dividing cells, a reduction on chlorophyll synthesis, induced water stress to plants, and decreased NO 3 - uptake, reduced nitrate and nitrite reductase activity, a direct effect of lead on protein synthesis, a decrease on the uptake and concentration of nutrients in plants. The strategies to minimize Pb hazard can be represented in: (a) Phytoremediation, through natural plants are able to bio-accumulate Pb in their above–ground parts, which are then harvested for removal such as, using Indian Mustard (Brassica juncea), Ragweed (Ambrosia artemisiifolia), Hemp Dogbane (Apocynum cannabium), or Poplar trees, which sequester lead in its biomass. (b) Good and ethical agricultural practices such as cultivation of vegetables crops as far from busy streets or highways and industry regions as well as nonuse of sewage sludge and waste water in cultivated soils. (c) Increasing the absorptive capacity of the soil by adding organic matter and humic acid. (d) Growing vegetable crops and cultivars with a low potential to accumulate lead, especially in soils exposed to atmospheric pollution. (e) Washing of leafy vegetables by water containing 1 % vinegar or peeling roots, tubers, and some fruits of vegetables before consumption may be an important factor in reducing the lead concentration.

We investigate how state involvement in the ownership of non-listed entrepreneurial firms affects pollution fees levied by national and provincial governments in China. While the national government sets minimum environmental standards, provincial governments can enact requirements that exceed these minimums, and they are largely responsible for enforcing even the national standards, so environmental levies can measure concessions that provinces make to encourage development and employment. Furthermore, state ownership is a good proxy for a firm’s political connections, which can influence (...) the relationship between the firm and the environmental authorities. We find that firms with state ownership pay lower environmental levies, which indicates that concessions are made for political or economic purposes. However, these concessions are conditional on the level of development of the province offering them, with better developed provinces providing fewer concessions. (shrink)

This study examined the constraining effect of economic performance on the relationship between CEO stakeholder orientations and four pollution performance categories. Economic performance was found to moderate the relationship for two of the four categories. Additionally economic performance was found to consistently interact with some CEO stakeholder orientations and not others.

Climate justice demands polluters to take responsibility for both present and future harm caused by past GHG emissions and for future harm caused by future GHG emissions. One problem with this is double climate taxation: people living in historical polluting countries must both shoulder the burden of an effective and inclusive climate transition and repay the climate debt incurred by their predecessors. Although double climate taxation might be defensible on normative grounds, it risks making climate justice politically infeasible. I therefore (...) maintain that global climate justice should focus on future, rather than past, climate harms. The forward-looking polluter pays principle (FL-PPP) can ensure both a cost-effective climate transition and a fair distribution of the climate burden, provided it is applied as follows: i) each country must introduce a carbon price calibrated to the global social cost of carbon; ii) each country must transfer part of carbon revenues collected at the country level to an international fund; iii) global carbon revenues must be redistributed on the basis of the country-level social cost of carbon. The FL-PPP burden can be made more progressive, moreover, if the formula for allocating global carbon revenues is adjusted through two coefficients, one consumption-based and one priority-sensitive.
