[Sustainable age(ing) in the context of climate change: state of research and conceptional considerations]. / Nachhaltiges Alter(n) im Kontext des Klimawandels: Stand der Forschung und konzeptioneller Ausblick.

BACKGROUND: Research on age and ageing is starting to consider challenges related to climate change; however, most work focuses on reaction needs rather than action possibilities of older people. MATERIAL AND METHODS: Based on a scoping review of 39 papers from the scientific literature the construction of age(ing) in the context of climate change and sustainability were analyzed and constrictions were revealed. Following these considerations, a model of "sustainable age(ing) in times of climate change" is proposed, which enables successful, active and sustainable ageing to be reconciled. RESULTS: The scoping review shows that older people are often considered as a homogeneous, vulnerable group and more or less helpless in the face of climate change. In the context of sustainability, they are attributed the role of a central cause or as part of the solution for environmental crises. The focus is broadened and contradictions and ambivalences are reconciled in this model of sustainable age(ing). DISCUSSION: Climate change can only be dealt with together. Research on age and ageing can support this on the basis of the model of sustainable age(ing) by providing important contributions to handling climate change and (re)actions regarding environmental crises.

Enhancing risk communication and environmental crisis management through satellite imagery and AI for air quality index estimation.

Due to climate change, the air pollution problem has become more and more prominent [23]. Air pollution has impacts on people globally, and is considered one of the leading risk factors for premature death worldwide; it was ranked as number 4 according to the website [24]. A study, 'The Global Burden of Disease,' reported 4,506,193 deaths were caused by outdoor air pollution in 2019 [22,25]. The air pollution problem is become even more apparent when it comes to developing countries [22], including Thailand, which is considered one of the developing countries [26]. In this research, we focus and analyze the air pollution in Thailand, which has the annual average PM2.5 (particulate matter 2.5) concentration falls in between 15 and 25, classified as the interim target 2 by 2021's WHO AQG (World Health Organization's Air Quality Guidelines) [27]. (The interim targets refer to areas where the air pollutants concentration is high, with 1 being the highest concentration and decreasing down to 4 [27,28]). However, the methodology proposed here can also be adopted in other areas as well. During the winter in Thailand, Bangkok and its surrounding metroplex have been facing the issue of air pollution (e.g., PM2.5) every year. Currently, air quality measurement is done by simply implementing physical air quality measurement devices at designated-but limited number of locations. In this work, we propose a method that allows us to estimate the Air Quality Index (AQI) on a larger scale by utilizing Landsat 8 images with machine learning techniques. We propose and compare hybrid models with pure regression models to enhance AQI prediction based on satellite images. Our hybrid model consists of two parts as follows:•The classification part and the estimation part, whereas the pure regressor model consists of only one part, which is a pure regression model for AQI estimation.•The two parts of the hybrid model work hand in hand such that the classification part classifies data points into each class of air quality standard, which is then passed to the estimation part to estimate the final AQI. From our experiments, after considering all factors and comparing their performances, we conclude that the hybrid model has a slightly better performance than the pure regressor model, although both models can achieve a generally minimum R2 (R2 > 0.7). We also introduced and tested an additional factor, DOY (day of year), and incorporated it into our model. Additional experiments with similar approaches are also performed and compared. And, the results also show that our hybrid model outperform them. Keywords: climate change, air pollution, air quality assessment, air quality index, AQI, machine learning, AI, Landsat 8, satellite imagery analysis, environmental data analysis, natural disaster monitoring and management, crisis and disaster management and communication.

Time to treat the climate and nature crisis as one indivisible global health emergency.

Over 200 health journals call on the United Nations, political leaders, and health professionals to recognise that climate change and biodiversity loss are one indivisible crisis and must be tackled together to preserve health and avoid catastrophe. This overall environmental crisis is now so severe as to be a global health emergency.

Anxiety in response to the climate and environmental crises: validation of the Hogg Eco-Anxiety Scale in Germany.

Background: As the climate and environmental crises unfold, eco-anxiety, defined as anxiety about the crises' devastating consequences for life on earth, affects mental health worldwide. Despite its importance, research on eco-anxiety is currently limited by a lack of validated assessment instruments available in different languages. Recently, Hogg and colleagues proposed a multidimensional approach to assess eco-anxiety. Here, we aim to translate the original English Hogg Eco-Anxiety Scale (HEAS) into German and to assess its reliability and validity in a German sample. Methods: Following the TRAPD (translation, review, adjudication, pre-test, documentation) approach, we translated the original English scale into German. In total, 486 participants completed the German HEAS. We used Bayesian confirmatory factor analysis (CFA) to assess whether the four-factorial model of the original English version could be replicated in the German sample. Furthermore, associations with a variety of emotional reactions towards the climate crisis, general depression, anxiety, and stress were investigated. Results: The German HEAS was internally consistent (Cronbach's alphas 0.71-0.86) and the Bayesian CFA showed that model fit was best for the four-factorial model, comparable to the factorial structure of the original English scale (affective symptoms, rumination, behavioral symptoms, anxiety about personal impact). Weak to moderate associations were found with negative emotional reactions towards the climate crisis and with general depression, anxiety, and stress. Discussion: Our results support the original four-factorial model of the scale and indicate that the German HEAS is a reliable and valid scale to assess eco-anxiety in German speaking populations.

Implications of Extractivism and Environmental Pollution in Mapuche Territories of the Araucania Region.

Chile is facing an environmental crisis and the territory of the Mapuche people is no exception. This is largely due to extractivism, which refers to the massive extraction and exploitation of natural resources in an indiscriminate manner. The objective of this study was to reveal the implications of extractivism and environmental pollution in Mapuche territories in the Araucanía region. The methodology used was qualitative, based on constructivist grounded theory. In-depth interviews and participant observation were used to collect data. The participants were 46 kimeltuchefes. The main results revealed extensive monocultures of non-native trees: pine and eucalyptus, which consume large amounts of water. They also revealed environmental pollution and indiscriminate forestry extractivism related to these trees, which generate soil degradation and water pollution. These consequences reduce biodiversity and disturb the ngenh (spiritual beings and protectors of nature). They also affect the Mapuche's agricultural activities and, in turn, their health and subsistence. In addition, non-native tree monocultures, environmental pollution and forestry extractivism transgress the az mapu (Mapuche code of ethics and behaviour), which disturbs the ethical, moral and spiritual relationship between the Mapuche and nature. They also have negative implications for the küme mogen (good living of the Mapuche), since they violate the balance and harmony between the Mapuche and all living beings, elements and spiritual beings that are part of nature. This also violates the reciprocity between the Mapuche and nature. It was concluded that there have been violations of the human rights of the Mapuche people, given that they are exposed to harmful environmental conditions that put their health and subsistence at considerable risk. In this sense, the Mapuche are experiencing a spiritual, physical, cognitive, attitudinal, affective and material imbalance. Ultimately, the state of Chile must generate intercultural environmental public and educational policies aimed at generating environmental awareness and creating actions to solve environmental problems in order to protect Mapuche and non-Mapuche territories.

AI explainability framework for environmental management research.

Deep learning networks powered by AI are essential predictive tools relying on image data availability and processing hardware advancements. However, little attention has been paid to explainable AI (XAI) in application fields, including environmental management. This study develops an explainability framework with a triadic structure to focus on input, AI model and output. The framework provides three main contributions. (1) A context-based augmentation of input data to maximize generalizability and minimize overfitting. (2) A direct monitoring of AI model layers and parameters to use leaner (lighter) networks suitable for edge device deployment, (3) An output explanation procedure focusing on interpretability and robustness of predictive decisions by AI networks. These contributions significantly advance state of the art in XAI for environmental management research, offering implications for improved understanding and utilization of AI networks in this field.

Global face mask pollution: threats to the environment and wildlife, and potential solutions.

Face masks are an indispensable low-cost public healthcare necessity for containing viral transmission. After the coronavirus disease (COVID-19) became a pandemic, there was an unprecedented demand for, and subsequent increase in face mask production and use, leading to global ecological challenges, including excessive resource consumption and significant environmental pollution. Here, we review the global demand volume for face masks and the associated energy consumption and pollution potential throughout their life cycle. First, the production and distribution processes consume petroleum-based raw materials and other energy sources and release greenhouse gases. Second, most methods of mask waste disposal result in secondary microplastic pollution and the release of toxic gases and organic substances. Third, face masks discarded in outdoor environments represent a new plastic pollutant and pose significant challenges to the environment and wildlife in various ecosystems. Therefore, the long-term impacts on environmental and wildlife health aspects related to the production, use, and disposal of face masks should be considered and urgently investigated. Here, we propose five reasonable countermeasures to alleviate these global-scale ecological crises induced by mask use during and following the COVID-19 pandemic era: increasing public awareness; improving mask waste management; innovating waste disposal methods; developing biodegradable masks; and formulating relevant policies and regulations. Implementation of these measures will help address the pollution caused by face masks.

COP27 Climate Change Conference: Urgent Action Needed for Africa and the World.

Wealthy nations must step up support for Africa and vulnerable countries in addressing past, present and future impacts of climate change.

The environmental crisis and the film First Reformed: Paths to paralysis and change.

The natural world has always been integral to our existence; currently, we are compelled to reckon with our assumptions about this connection with mounting urgency. Individual reactions to the environment are influenced not only by the sociocultural surround, but also by one's internal world, particularly whether one's internal objects are felt to have been irreparably damaged or are potentially salvageable. Excessive guilt about destructive impulses can limit one's ability to recognize individual responsibility for the current situation without catastrophizing the weight of one's ecological footprint. Delusional solutions may be adopted, valorizing extreme forms of engagement. The film First Reformed illustrates what appear to be divergent approaches to the planet: ruthless exploitation by an industrialist versus an impassioned objection to destruction of the environment for economic gain. In this narrative, both are underpinned by a paranoid-schizoid mindset. We investigate the dynamics of this psychic state, which results in a constricted perception and an absence of constructive agency with respect to the environmental crisis. We present an alternative conceptualization of the natural world's place within a person's psychic equilibrium. We emphasize that a more integrated relationship with the environment can facilitate concerned, preservative action on behalf of the natural world and ourselves.

On the syndemic nature of crises: A Freeman perspective.

In this paper we draw a parallel between the insights developed within the framework of the current COVID-19 health crisis and the views and insights developed with respect to the long term environmental crisis, the implications for science, technology and innovation (STI) policy, Christopher Freeman analyzed already in the early 90's. With at the time of writing, the COVID-19 pandemic entering in many countries a third wave with a very differentiated implementation path of vaccination across rich and poor countries, drawing such a parallel remains of course a relatively speculative exercise. Nevertheless, based on the available evidence of the first wave of the pandemic, we feel confident that some lessons from the current health crisis and its parallels with the long-term environmental crisis can be drawn. The COVID-19 pandemic has also been described as a " syndemic ": a term popular in medical anthropology which marries the concept of 'synergy' with 'epidemic' and provides conceptually an interesting background for these posthumous Freeman reflections on crises. The COVID-19 crisis affects citizens in very different and disproportionate ways. It results not only in rising structural inequalities among social groups and classes, but also among generations. In the paper, we focus on the growing inequality within two particular groups: youngsters and the impact of COVID-19 on learning and the organization of education; and as mirror picture, the elderly many of whom witnessed despite strict confinement in long-term care facilities, high mortality following the COVID-19 outbreak. From a Freeman perspective, these inequality consequences of the current COVID-19 health crisis call for new social STI policies: for a new "corona version" of inclusion versus exclusion.

Experiences of citizenship in precarization: An ethnography from northern Colombia in the time of COVID-19.

This article is the result of qualitative research on current ways of being a citizen in northern Colombia during the era of COVID-19. In a region characterized by impoverished communities, the study area becomes a privileged place in which to understand how communities in so-called "developing countries" face a pandemic with their local resources. To place the reader, we discuss the history of this place, the town of Taganga, located in the city of Santa Marta in northern Colombia. Likewise, its culture and social structure are described, as well as the current situation related to access to electricity, water, garbage collection, and food. The article shows how, through local means, today's communities seek to establish settlements with essential services, such as water and electricity, without any relationship with the state.

Technoscientific control of nature: The ultimate paradox.

The current interlinked environmental and socioeconomic global crises constitute the gravest threat to humanity's well-being, indeed survival, today. Studies of the historical roots and contemporary manifestations of the various elements of these crises-including accelerating environmental degradation, unfettered capitalist technoscientific/industrial expansion, overpopulation, and overconsumption-are plentiful. Also well-known is the influence of Francis Bacon's writings, particularly The Advancement of Learning (1605), Novum Organon (1620), and the utopian New Atlantis (1627), on the development of empiricism and the modern scientific method as well as the reform and organization of scientific research. Bacon's significance for the founding of the Royal Society of London (1660) and for the plan and structure of the Encyclopedie (1751-1772), coupled with his oft-cited aphoristic injunctions to study nature to control/dominate it, are staples in the lore and justification of technoscience. I argue that the enduring appeal of so-called Baconianism derives, in part, from a fundamental misappropriation of certain of Bacon's original ideas. Specifically, the complex ethical and religious framework within which Bacon situated his vision of scientific and technological development was discarded (or ignored) so that, by the early decades of the 18th century, Baconianism had come to be understood almost exclusively for its utilitarian role in society. This deracinated version became the familiar trope of technoscience's unlimited potential to transform nature (including human nature and behavior) in the service of an ideology of industrial/consumerist expansion since then. Linkage between the history of science/technology and addictive consumerism, apparent by the close of the 19th century, has been insufficiently examined. Such addictive consumerist behavior and continued virtually unregulated industrialization and production, were effectively removed from ethical scrutiny and a high degree of material acquisition and personal/societal rapaciousness became the norm rather than the exception in most countries. I suggest that further historical deconstruction of this denuded Baconianism will yield important insights in the search for viable solutions to the present global socioenvironmental crises.

Artisanal mollusc fisheries co-management in Brazil and Italy: Institutional innovations to address environmental crisis.

Initiatives of artisanal fisheries co-management and the construction of differentiated markets for seafood products have been emerging in different parts of the world, as an institutionalized way of coping with a global fishery crisis. This paper analyses some institutionalization processes of artisanal mollusc fisheries, considering the role of co-management in two Brazilian and Italian protected areas (Resex Pirajubaé and Conero Regional Park). Within a theoretical framework aiming at moving beyond the dualism between nature and society, the methodology of multiple-case-study has been used to carry on research about mollusc artisanal fisheries co-management networks in their constitution and development. The paper analyses how these networks are organised in the two contexts and the relations social actors have been developing for a sustainable fishery as a possible way to influence and increase their capacity to address environmental crisis. In the artisanal mollusc fishery co-management experiences, fishers' participation may favour institutional innovations and the co-management networks stability may be generated by the institutions legitimacy. Furthermore, the case studies offer complementary insights to better understand the linkage between artisanal fishery institutionalization processes, common natural resources co-management and value aggregation for traditional seafood. Artisanal mollusc fishery co-management experiences should be stimulated and investigated since they can help in diagnosing early climate and environmental changes in the oceans.

Invertendo o enfoque das "crises migratórias" para as "migrações de crise": uma revisão conceitual no campo das migrações / From "migration crisis" to "crisis migration": a conceptual review within the migration studies field / De "crisis migratoria" a "migraciones de crisis": una revisión conceptual en el campo de estudios de las migraciones

O presente artigo se propõe a debater um novo conceito no campo de estudos migratórios - as migrações de crise -, o qual traz à luz os processos, motivos e fatores vivenciados por populações afetadas por crises e que podem contribuir para processos migratórios de indivíduos, famílias e comunidades como um todo. Introduzindo diversas categorias correlatas - como a eventualidade, a imobilidade (ou enclausuramento) e a não escolha -, adota-se um direcionamento metodológico e conceitual que aponta para as crises como propulsoras das migrações. Dessa maneira, busca-se tensionar a ideia de que as migrações geram crises aos Estados-nação receptores de movimentos significativos de pessoas - a qual notavelmente se consolida pela disseminação do termo "crise migratória", em especial, nos discursos políticos e midiáticos correntes. A delimitação do novo conceito proposto e da sua metodologia de estudo pautou-se pela revisão bibliográfica da literatura especializada na área, com foco em pesquisas recentes sobre as migrações de crise e suas implicações tanto na esfera local como na internacional. Ao final do texto, levantamos os desafios e as contribuições de tal conceito, envolvendo debates centrais no campo das migrações, inobstante questões teórico-metodológicas

This article aims to debate a new concept within the migration studies field which is named "crisis migration", shedding light on the processes, motives and factors that influence the movement of populations affected by crisis. Introducing other interrelated categories - such as eventuality, immobility and non-choice - , the article is guided by a methodological and conceptual perspective that understands crisis as a driver to migration. Therefore it seeks to defy the idea that migrations generate crisis to nation-states receiving large contingents of people. This idea has been consolidated by the term "migration crisis" especially disseminated in the midia and political discourses. Our discussion of the new concept was based on bibliographic review, focusing on recent researchs in respect to crisis migration and its unfoldings not only in the local but also in the international scenario. Finally, we bring about the challenges as well as the contributions of this concept, which involve unsolved central debates within the migration field.

Este artículo tiene como objetivo discutir un nuevo concepto en el campo de los estudios migratorios, las migraciones de crisis, que saca a la luz los procesos, los motivos y los factores experimentados por las poblaciones afectadas por las crisis y que pueden contribuir a los procesos migratorios de las personas, las familias y comunidades en su conjunto. Al introducir varias categorías relacionadas, como eventualidad, inmovilidad (o confinamiento) y no elección, se adopta una dirección metodológica y conceptual que apunta a las crisis como motores de la migración. De esta manera, buscamos tensionar la idea de que la migración genera crisis en los Estados-nación que reciben movimientos significativos de personas, lo que se consolida notablemente por la difusión del término crisis migratoria, especialmente en los discursos políticos y mediáticos actuales. La delimitación del nuevo concepto propuesto y su metodología de estudio fue guiada por la revisión bibliográfica de la literatura especializada en el área, con un enfoque en investigaciones recientes sobre migraciones de crisis y sus implicaciones tanto a nivel local como internacional. Al final del texto, planteamos los desafíos y las contribuciones de dicho concepto, involucrando debates centrales en el campo de las migraciones, a pesar de los problemas teóricos y metodológicos que aún no se han superado suficientemente dentro de este.

Reaching Up, Down, In, and Around: Couple and Family Coping During the Coronavirus Pandemic.

The worldwide coronavirus (COVID-19) has had profound effects on all aspects of life: physical health, the ability to travel locally or to more distant destinations, material and financial resources, and psychosocial wellbeing. Couples, families, and communities and individual persons in those relationships have struggled to cope with emerging depression, anxiety, and trauma, and the rise of relational conflict. In this article, we suggest that the existential nature of the pandemic's challenges requires more than just the usual psychosocial interventions. We propose a taxonomy of responses to foster coping and resilience-"Reaching Up, Down, In, and Around." "Reaching Up" includes accessing spiritual, religious, and ethical values. "Reaching Down" includes ideas and practices that foster a revised relationship with the Earth and its resources, and that engage families to participate in activities that aid the Earth's recovery from decades of human-caused damage. "Reaching In" represents a turn towards experiences available in the mind and in shared minds in relationships that provide pleasure, excitement, joy, and peace, given that external sources of these emotions are of limited availability due to quarantine. "Reaching Around" involves reframing the mandate for "social distancing" as fostering social connection and support while maintaining physical distancing. The challenges for family therapists, whose practices are confined largely to online therapy, and who are struggling with the same fears and constraints as those persons they are attempting to help, are also discussed.

El coronavirus (la COVID-19) mundial ha tenido efectos profundos en todos los aspectos de la vida: en la salud física, en la posibilidad de viajar a nivel local o a destinos más distantes, en los recursos materiales y económicos y en el bienestar psicosocial. Las parejas, las familias, las comunidades y las personas individuales de esas relaciones se han esforzado para hacer frente a la depresión, la ansiedad y el trauma emergentes, y al aumento del conflicto relacional. En este artículo, sugerimos que la índole existencial de las dificultades de la pandemia necesita más que solo las intervenciones psicosociales habituales. Proponemos una taxonomía de respuestas para fomentar el afrontamiento y la resiliencia: "Llegar arriba, abajo, adentro y alrededor". "Llegar arriba" implica acceder a valores espirituales, religiosos y éticos. "Llegar abajo" implica ideas y prácticas que fomenten una relación revisada con la Tierra y sus recursos, y que capten la atención de las familias para participar en actividades que ayuden a la recuperación de la Tierra de décadas de daño causado por los humanos. "Llegar adentro" representa un giro hacia experiencias que hay en la mente y entre mentes por relaciones que brindan placer, entusiasmo, alegría y paz, dado que la disponibilidad de las fuentes externas de estas emociones es limitada debido a la cuarentena. "Llegar alrededor" implica replantear la orden de "distanciamiento social" como fomento de la conexión social y el apoyo mientras se mantiene la distancia física. También se explican las dificultades para los terapeutas familiares, cuyas prácticas están limitadas en gran medida a la terapia en línea, y quienes están luchando contra los mismos miedos y limitaciones que esas personas a quienes intentan ayudar.

La naturaleza en la Constitución: visiones indígenas y propuestas ante la crisis / Nature and the Constitution: indigenous perspectives and proposals for the crisis / A natureza na Constituição: visões indígenas e propostas diante da crise

Este trabajo analiza la forma en que el derecho y la Constitución del 80 tratan a la naturaleza. Esta visión se contrapone con los enfoques de las filosofías de los pueblos indígenas andinos y mapuche, las cuales apuntan a la interrelación, interdependencia y reciprocidad en las relaciones entre sociedad y naturaleza. A partir de los problemas ambientales que la ciencia ha sistematizado y que afectan al mundo y al país, este trabajo elabora propuestas para una nueva configuración de lo ambiental y la naturaleza en la Constitución.

This paper assesses how the law and the 1980 Constitution deal with nature. This view contrasts with the perspective of the philosophies of the indigenous Andean and Mapuche peoples which consider the interrelation, interdependence and reciprocity in the relationships between society and nature. From the standpoint of the environmental problems that science has systematized and that affect the world and the country, this paper puts forward proposals for a new configuration for issues concerning the environment and nature in the Constitution.

Afterword: Lives Interrupted, Trends Continued?

The COVID-19 pandemic is nowhere near over. Some things, however, seem relatively clear. So far, the agendas of the world's most powerful actors seem unchanged-or, indeed, accelerated. Partly as a result, disease mortality and economic losses have fallen largely on poorer people, though deaths so far have been concentrated among poorer people in rich countries. Consequently, the pandemic's implications look very different at the local, subnational, and international levels-although at all levels, they thus far reflect accelerations of preexisting trends more than new departures. Many developments reflect remarkable gains in human capacity to cope with disasters-a point highlighted by comparisons to the 1919 flu and other historical events pandemics made by the authors in this forum. Those gains are particularly evident in Asia, though they look more precarious in South Asia and Southeast Asia than in East Asia; this has contributed to a marked shift in rhetoric about global "sickness" and health and seems consistent with prophecies of a coming "Asian century." However, COVID-19 may not be a singular event like 1919 but may portend a wave of environmental emergencies; in that scenario, no world region has exhibited as much resilience as it would need.

Hacia una fundamentación de la bioética ambiental desde la visión de Fritz Jahr, Aldo Leopold y Van Rensselaer Potter / Towards the Foundations of Environmental Bioethics from the View of Fritz Jahr, Aldo Leopold, and Van Rensselaer Potter / Em direção a uma fundamentação da bioética ambiental a partir da visão de Fritz Jahr, Aldo Leopold e Van Rensselaer Potter

Propósito/Contexto. Este artículo hace una reflexión acerca de los planteamientos ecológicos inherentes al cuerpo teórico de la bioética, en la búsqueda de una delimitación de la bioética ambiental, a partir de los planteamientos de Fritz Jahr, Aldo Leopold, Van Rensselaer Potter y de autores latinoamericanos que promueven un cambio de paradigma en la relación del ser humano con los ecosistemas. Metodología/Enfoque. Se hace una investigación cualitativa, apoyada en un análisis hermenéutico de los estudios bioéticos consultados, correspondientes al periodo de 1970 a 2018. Se usan programas especializados para establecer relaciones de coocurrencia y la visualización de las comunidades semánticas. Resultados/Hallazgos. La dimensión ambiental de la bioética se estructuró a partir de las ideas fundantes de Jahr, Leopold y Potter, que marcan una línea conceptual que establece un abandono de la ética antropocéntrica, para avanzar hacia un modelo ecocéntrico. Por tanto, la bioética ambiental asume un rol integrativo entre el ser humano y las comunidades ecosistémicas. Discusión/Conclusiones/Contribuciones. Se consolidan, como ejes estructurantes de la bioética ambiental, la defensa de la vida, la creación de relaciones armónicas entre las personas y los seres no humanos. También se amplían los límites de la moral humana para incluir a los animales, las plantas y el territorio en nuevos escenarios de convivencia; así mismo, se establece la naturaleza como sujeto de derechos.

Purpose/Context. This article reflects on the ecological approaches to the body of bioethics theories to delimit environmental bioethics based on Fritz Jahr, Aldo Leopold, Van Rensselaer Potter, and Latin American authors who promote a paradigm shift in the human being-ecosystem relationship. Method/Approach. This qualitative research is supported by a hermeneutical analysis of bioethical studies between 1970 and 2018. It uses specialized programs to establish cooccurrence relationships and view semantic communities. Results/Findings. The environmental dimension of bioethics was structured from the founding ideas of Jahr, Leopold, and Potter, who established a conceptual line that abandons anthropocentric ethics to move towards an ecocentric model. Therefore, environmental bioethics assumes an integrating role between humans and ecosystem communities. Discussion/Conclusions/Contributions. The defense of life and the creation of harmonious relationships between people and non-human beings are con-solidated as structuring lines of environmental bioethics. The limits of human morality are also expanded to include animals, plants, and territory in new coexistence settings, and nature is established as a subject of rights.
