Recent studies challenge the classical view that the origin of animal life was primarily controlled by atmospheric oxygen levels. For example, some modern sponges, representing early‐branching animals, can live under 200 times less oxygen than currently present in the atmosphere – levels commonly thought to have been maintained prior to their origination. Furthermore, it is increasingly argued that the earliest animals, which likely lived in low oxygen environments, played an active role in constructing the well‐oxygenated conditions (...) typical of the modern oceans. Therefore, while oxygen is still relevant to understanding early animal evolution, the relationships between the two might be less straightforward than previously thought. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Living with Blindness and Fibromyalgia while Occupying AgingKatherine SchneiderI’m blind from birth and in middle age developed fibromyalgia. I’ve retired from a thirty year career as a clinical psychologist and am working on my third book tentatively titled “Occupying Aging: Delights, Disabilities and Daily Life.” My relationship with medical professionals includes gratitude (without good care I would not be alive) and also frustration for assumptions often made about my (...) abilities. I write from the perspectives of an impatient patient, woman living in the United States, former provider of mental health services, person with both invisible and visible disabilities, and boomer moving into the world of the aged. My stories are mine of course, but when I swap medical stories with blind friends, similar happenings abound.When my mom fell down the stairs at a friend’s house, five months pregnant with me, she was told to go to bed for the next four months to save the pregnancy. Thus began the impact of health care professionals on me. I was born a month premature and spent my first month in an incubator. In 1949 it wasn’t known that the enriched oxygen atmosphere in an incubator would cause blindness. At least one lawsuit was filed against physicians and a hospital by a person blinded in this way. A large out–of–court settlement was received. The way I look at it, the health care community did the best they knew and without enough oxygen, I would have died.Early in my life, my parents took me to several ophthalmologists to see what could be done for my vision. Family folklore has it that I could smell a hospital as we entered and would begin howling. These early traumatic experiences may have led to my current healthy lifestyle so I don’t have to go to doctors much now. By about age five, it was clear that nothing could be done about my vision. For the next twenty years my forays into the health care system were for tonsillitis, sprains, and the usual childhood ills.In my early twenties, I developed acute glaucoma in one eye—caused, I’m convinced, by birth control pills. In seeking treatment for this condition, I encountered the first truly insensitive physician I’d met, who said, “Your eyes aren’t doing you any good; let’s take them out.” I was horrified! They were my eyes. I was attached to them, psychologically as well as physically. It turned out that a simple operation relieved the pressure and allowed me to keep my eyes. True, they are not the best looking big brown eyes around, but they did come with the package.Life with blindness seemed quite straightforward until my early forties, when I developed extreme fatigue and pain all over. I was worried. I knew a blind woman who had developed multiple sclerosis and I admired her, but I did not want to walk in her brave footsteps. Then a college student came to see me with the same symptoms and said that she had recently been diagnosed with fibromyalgia. I am often very empathetic with people’s concerns, but this time she complimented me by saying, “You’re great! You seem to know just how I feel.” I sagely counseled her about portioning out her energy carefully, prioritizing, using short cuts, and taking elevators when possible. Being an adult [End Page 216] student used to overachieving, she did not like what I was saying, but said she’d try to follow my advice because she could no longer do it all.What finally broke through my own denial was the day coiling up a hose and dragging it to the basement for the winter took me an hour. It left me totally exhausted and I figured that even being middle aged couldn’t account for feeling that awful.After a thorough physical and plenty of blood work to rule out Lyme disease and multiple sclerosis, I was diagnosed with fibromyalgia and placed on low doses of antidepressants to help me sleep through the night. The medication worked and I began to feel like myself again. My battle to accept that... (shrink)

RubisCO is Earth's main enzyme responsible for CO2 fixation via carboxylation of ribulose-1,5-bisphosphate into organic matter. Besides the carboxylation reaction, RubisCO also catalyzes the oxygenation of RuBP by O2, which is probably as old as its carboxylation properties. Based on molecular phylogeny, the occurrence of the reactive oxygen species -removing system and kinetic properties of different RubisCO forms, we postulated that RubisCO oxygenase activity appeared in local microoxic areas, yet before the appearance of oxygenic photosynthesis. Here, in reviewing the (...) literature, we present a novel hypothesis: the RubisCO early oxygenase activity hypothesis. This hypothesis may be compared with the exaptation hypothesis, according to which latent RubisCO oxygenase properties emerged later during the oxygenation of the Earth's atmosphere. The reconstruction of ancestral RubisCO forms using ancestral sequence reconstruction techniques, as a promising way for testing of RubisCO early oxygenase activity hypothesis, is presented. RubisCO catalyzes carboxylation and oxygenation of ribulose-1,5-bisphosphate. Carboxylating properties of RubisCO are an ancient way for CO2 fixation into organic matter. However, an evolutionary importance of oxygenase activity of RubisCO remains enigmatic. Here, we formulated RubisCO early oxygenase activity hypothesis. According to this hypothesis, RubisCO oxygenase activity appeared yet before the appearance of oxygenic photosynthesis. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Cry of the CaregiverLeilani RoseberryMy story is about the work-related grief I've experienced while working as a certified nurse assistant (CNA). I'll begin with my first days as a newly hired CNA. It was day two of my first week, and while I walked down the hallway I noticed something unusual lying on the floor near the opposite side of building. The hall of the retirement community was quite (...) long and it wasn't until I was halfway down the hall before I realized it was a resident lying on the floor. I ran the rest of the way, only to discover the person was dead. I was very shaken.I hadn't received proper orientation in regards to this facility and I didn't know whom I should contact. It didn't help that I wasn't carrying a cell phone (I had been taught that we shouldn't keep our cell phones with us while on duty). There were no emergency phones and no pull cords available in the halls. I was very shaky and nervous. I admit that I was scared. There was no one around but the body and myself. It was after hours and the staff at the reception desk had already clocked out, so I thought. I had no resort but to knock on the door of a nearby resident and ask to use the phone. This created a commotion in the hall and drew a crowd of residents from their apartments and the atmosphere then became extremely sorrowful. [End Page 151]It was only then that I learned that a night staff person was on duty and how I could contact them. I had to learn this from a resident who was not my client. The person on staff that night provided me with a thorough tour and orientation of the building. I believe that my agency should have been the one to provide such an orientation. It took me a few weeks or more before I could close my eyes at night without seeing the body lying in the hallway. I wasn't offered any support from the agency; the next day was business as usual.About two weeks later, another resident I cared for passed away. Then another, and another, and so on, but I wasn't actually present when the deaths occurred. They passed away while I was off work. It bothered me just the same to know they were gone. I cared about my clients, but for the agency the clients meant money and I had to remain focused and keep on working.At this retirement community the residents were not cared for in a one-to-one fashion by the agency I worked for, but were visited during intervals throughout the course of my shift. I was on call for emergencies and other needs as well. Again, I cared for all those in my run, but I never became as close to any client as when I changed agencies and accepted the following assignment.The new homecare agency I worked for provided one-to-one care. It was shift work, eight hours, one-to-one with one client or a married couple. One day, just after I began my morning shift, my client suffered respiratory distress, his pulse raced while his oxygen level dropped, despite the O2 he used. My client died while gasping for air. This was the first time I had been present and witnessed the fear in a dying person's eyes or experienced losing a client like this, but my emotions had to be set aside. I had work to do. I assisted the hospice team with the post-mortem care and other tasks, plus cared for the spouse.After the post-mortem care was completed, I took a step back as the family gathered into the little room and surrounded my client. The room was silent except for the sighs, the sobs, and the wailing. It was heartbreaking to stay in the room. I bit my lip and tried to hold back tears. Not to mention the weak-in-the-knees floating feeling I experienced. I felt like... (shrink)

Ferritins (FTs) are iron storage proteins that are involved in managing iron‐oxygen balance. In our work, we present a hypothesis on the putative effect of geological changes that have affected the evolution and radiation of ferritin proteins. Based on sequence analysis and phylogeny reconstruction, we hypothesize that two significant factors have been involved in the evolution of ferritin proteins: fluctuations of atmospheric oxygen concentrations, altering redox potential, and changing availability of water rich in bioavailable ferric ions.Fish, ancient amphibians, (...) reptiles, and placental mammals developed the broadest repertoire of singular FTs, attributable to embryonic growth in aquatic environments containing low oxygen levels and abundant forms of soluble iron. In contrast, oviparous land vertebrates, like reptiles and birds, that have developed in high oxygen levels and limited levels of environmental Fe2+ exhibit a lower diversity of singular FTs, but display a broad repertoire of subfamilies, particularly notable in early reptiles.

In lieu of an abstract, here is a brief excerpt of the content:Darwin Meets Literary TheoryEllen DissanayakeEvolution and Literary Theory, by Joseph Carroll; xi & 518 pp. Columbia: University of Missouri Press, 1995, $44.95.In my experience, most literary theorists, even those who participate in conferences called “Literature and Science,” know little about evolution, and don’t want to know. For them, “science” means information theory, chaos or catastrophe theory, fractals, pataphysics, “autopoeisis” or self-organization, emergence, cyborgs, hypertext, virtual signs and other aspects (...) of sci-fi, or techno-politics. (I encountered these subjects at a comparative literature conference I attended in March 1995.) These “scientific” positions are used as trendy metaphors for talking about chance, uncertainty, accident, ideology, and multidimensionality in literary works or in the aims of their authors. In other words, the buzzwords of contemporary science become one more angle from which to view or project another facet onto the glassy, self-reflective edifice of contemporary literary theory, rather than a means from which to shatter it and build again from scratch with more earthy, substantial materials. Joseph Carroll’s book provides the view and the means for this genuinely new and constructive (if initially destructive) possibility.It is ironic that in the present critical climate the very virtues of the book might be seen by some as faults—e.g., the lucid, elegant writing and the erudition and interdisciplinarity of the work as a whole. Carroll [End Page 229] writes clearly, authoritatively, without jargon, and with frequent, delicious wit. His values, aims, explanations, evidence, and criticisms are concisely and plainly stated. This is in marked contrast to the enigmatic and idiosyncratic nature of much recent criticism, and might have the initially disorienting effect of returning to earth and breathing pure oxygen after one has become accustomed to the thin and rarefied atmosphere of remote, icy peaks.Carroll offers wide-ranging and illuminating discussions of standard literary and critical works from both the European and Anglo-American tradition over the past several centuries, and refers to dozens of writers from diverse periods and nationalities. Additionally he enlists, and criticizes where appropriate, ideas from such diverse nonliterary figures as Darwin himself and writers about Darwin, T. H. Huxley, Konrad Lorenz, John Bowlby, Sir John Eccles, the prominent sociobiologists and evolutionary psychologists, S. J. Gould, Richard Lewontin, Derek Bickerton, Piaget, Karl Popper, Thomas Kuhn, Clifford Geertz, H. J. Eysenck, Cardinal Newman, Thorstein Veblen, Trotsky, Raymond Williams, and Richard Rorty, among others.One can be forgiven for wishing to forego an exploration of this demanding array of knowledge argued from the unfamiliar perspective of evolutionary biology. For in order seriously to consider Carroll’s new way of looking at human endeavor (including literature) one must also look critically at what was laboriously mastered during all those years of graduate school and tenure-driven writing for publication. No one wants to be persuaded to give up a view of the world that has been mastered with painstaking diligence. Still less does anyone want to spend time with something that according to conventional academic wisdom is downright wrong-headed. This is really the challenge of Carroll’s book—because such minor matters as the plain unfashionable title, clear writing, impressive erudition, and dated or forgotten thinkers can be overcome if the stakes are high enough.I wish to suggest that the stakes are high enough and that the time is right for this inevitable change of viewpoint. Along with others in diverse fields such as cognitive and developmental psychology, personality theory, neurology, medicine, sociology, political science, epistemology, cultural anthropology, ethics, and linguistics, I find the Darwinian perspective to offer the most comprehensive and viable possibility for an understanding of human behavior and culture, including the arts. Joseph Carroll admirably articulates this position and applies it to literary theory. I invite scholars who think that evolutionary explanations [End Page 230] are erroneous, dangerous, reductionist, simplistic, or irrelevant to read Carroll and deal seriously with his arguments. His book should be the central text for theory classes and seminars, as well as the subject of conferences. Those who would dismiss it should have the courage and curiosity to lay aside their misgivings and have a look. Especially those who are dissatisfied with the surfeit... (shrink)

By analysing three works of fiction set in Havana, Fresa y Chocolate by Tomas Gutiérrez Alea and Juan Carlos Tabi, Retour à Ithaque by Laurent Cantet and Viva by Paddy Breathnach, we propose to study the Cuban capital as a sick body, as an architecturally, economically, politically and socially dilapidated organism. Its citizens struggle to survive, lacking basic necessities and trapped under a claustrophobic political and social surveillance, which the film directors convey through the use of a variety of aesthetic (...) devices. There is a form of symbiosis between Havana and its inhabitants. The characters are confined in a labyrinth of alleys, stairs and narrow corridors, enveloped in a nocturnal atmosphere. The constricted arteries through which they move show that the body of Havana lacks oxygen. Its inhabitants need to find spaces to breathe and to express their authentic selves, to regenerate. This space is to be found behind Havana’s façades, behind its closed doors and even on a roof-top terrace. These private spaces reveal the dual nature of the city and its people, and constitute pockets of liberty as well as places of catharsis. The external façade presents a socially acceptable figure while covering and protecting the authentic self. The private spaces provide the physical and mental oxygen that the soul of Havana needs to survive. It is here that individual liberties flourish, allowing rights to be asserted, and art to be both preserved and created. The premise of a spiritual transformation begins to take form. (shrink)

We barely talk about them and seldom know their names. Philosophy has always overlooked them; even biology considers them as mere decoration on the tree of life. And yet plants give life to the Earth: they produce the atmosphere that surrounds us and they are the origin of the oxygen that animates us. Plants embody the most direct, elementary connection that life can establish with the world. In this book, philosopher Emanuele Coccia argues that, as the very creator (...) of atmosphere, plants occupy the fundamental position from which we should analyze all elements of life. From this standpoint, we can no longer perceive the world as a simple collection of objects or a universal space containing all things, but as the site of a veritable metaphysical mixture. One implication of Coccia’s claim is that since the atmosphere of life is rendered possible through plants alone, life only perpetuates itself through the very circle of consumption undertaken by plants. In other words, life exists only insofar as it consumes other life, removing any moral or ethical considerations from the equation. In contrast to trends of thought which discuss nature and the cosmos in general terms, Coccia’s account brings the infinitely small together with the infinitely big, offering a radical redefinition of the place of humanity within the realm of life. Faced as we are with ever more complex and urgent ecological questions, this path-breaking account of the life of plants will appeal not only to students and scholars of philosophy but to a wide range of readers interested in our relation to the natural world.

In lieu of an abstract, here is a brief excerpt of the content:Why Gaia?Massimo Pigliucci (bio)The Gaia Hypothesis: Science on a Pagan Planet, Michael Ruse, Chicago: University of Chicago Press, 2013. 272 pages.“The Gaia Hypothesis: Science on a Pagan Planet tells a story that comes out of the 1960s, a story that reflects all of the beliefs and enthusiasms and tensions of that decade.” So begins Michael Ruse’s fascinating, if at times puzzling, exploration of James Lovelock’s famous idea that our (...) planet is, in a serious scientific sense, a living organism with a tendency of taking care of (her)self. But why tell this particular story, especially considering that Gaia hardly makes an appearance in today’s scientific or philosophical publications, and doesn’t even seem quite that popular with the lay public as it used to be? Because, as Ruse tells us near the end of the book, at the onset of chapter seven: “the paradox that set us on our path [is] why the scientific community reacted so negatively to the Gaia hypothesis, whereas the public reaction was so positive.”As it turns out, there is a good answer to that conundrum, one that Ruse himself lays out clearly in the last chapter of the book, and which makes the reader wonder why this should count a paradox at all. But we will get there in due time. First, the basics: the so-called Gaia hypothesis is the brainchild of iconoclastic inventor-turned-independent-scientist James Lovelock, who later got significant help in elaborating (and promoting) his ideas from another iconoclast, biologist Lynn Margulis. By the time you get to the end of Ruse’s engaging book, however, you won’t have gained a particularly good understanding of what the hypothesis actually consists. But that’s not Ruse’s fault, it is Lovelock’s (and Margulis’). At times it sounds like the entirely uncontroversial claim that the Earth’s [End Page 117] biosphere is a somewhat homeostatic system—i.e., a biophysical system that is resistant to major changes, at the least within a certain range (the planet’s atmosphere, after all, did change dramatically early on, increasing its oxygen content as a result of the evolution of photosynthetic organisms—the anaerobic life forms that had up to that point been dominant did not appreciate the novelty). At other times the claim is downright preposterous: the Earth literally is a living organism (according to Lovelock) (Chapter 7),1 a finding that allegedly puts in question the whole Darwinian view of biological evolution (according to Margulis) (Chapter 7), a position that can only be characterized as nonsense on stilts. At yet other moments, Gaia is presented as just a metaphor to help us wrap our minds around the complexities (and homeostatic properties) of the world’s ecosystems (Chapter 8). It is this never-ending oscillation between the trivial and the bizarre that has led the majority of scientists to write off Gaia, to the chagrin of Lovelock, Margulis, and a large number of New Age tree huggers from the 1960s.Indeed, the scientific reaction to Gaia was swift and ranging from the condescending to the unforgiving. Evolutionary biologist John Maynard Smith—never one to mince words—called it “an evil religion” (Chapter 2). Another evolutionary biologist, Stephen Jay Gould (whose own disagreements with Maynard Smith became legendary) said that “Gaia strikes me as a metaphor, not a mechanism” (Chapter 2). Ecologist Robert May, who eventually became president of the Royal Society, called Lovelock “a holy fool” (Chapter 2). The highly respected theoretical biologist W.D. Hamilton said that in order for the hypothesis to work, it would require “treaties between Neptune and Zeus, a Gaian Interpol, conventions about bills of lading for chemical transport by air and water, and so on” (Chapter 7). Finally, Richard Dawkins accused Lovelock of committing the fallacy of “the BBC theorem,” assuming (or wishfully thinking) that the world is a harmonious place, just like in naive BBC nature documentaries (Chapter 2).You get the gist: pretty much from the beginning, and with very few exceptions, the scientific establishment rejected Gaia on the grounds that it is not a scientific hypothesis at all, and that its main tenets actually go against pretty...

In lieu of an abstract, here is a brief excerpt of the content:Witnessing Trauma:Emotional Challenges in Medical InterpretationMaja Milkowska-ShibataHaving a background in public health but no clinical experience, I never expected to be given the opportunity to work directly with patients. This changed when I became involved in medical interpretation. During my first year of service, I mostly assisted with primary care appointments until I was assigned to my first appointment in a cancer treatment center. The moment I stepped into (...) the distinctive atmosphere of that place, the gravity of the patients' circumstances became strikingly apparent. Each individual was [End Page E8] suffering from a life-threatening condition, which was unlike anything I was used to witnessing.The staff seemed to know each and every patient. I noticed a patient in a wheelchair accompanied by a relative carrying an oxygen tank. Someone brought gifts for the receptionists. A Christmas tree sat in the corner of the waiting area, ready for the holidays. The facility clearly conveyed an effort to resemble a home-like environment. "They must be regulars," I thought grimly.After completing a routine appointment with an elderly patient who was feeling weak, the patient requested an IV drip. My official assignment was over, and I could have gone home at that point, but something compelled me to stay. As I interpreted the nurse's instructions for setting up the drip, I could not help but notice the vulnerability of the patient, who had a thin and frail physique. The patient seemed grateful for my presence, so I settled into a chair in the corner and waited patiently.Soon, the patient drifted off to sleep, and I checked on them every now and again to make sure they were fine. The room became quiet, and I hoped the patient would not be disturbed by the sound of an ambulance or another patient seeking treatment. Although they were in capable hands, I found myself standing guard, metaphorically speaking. During the two hours it took for the drip to finish, I reflected on the emotions growing within me.It suddenly dawned on me: I had not been there for my own father during his battle with cancer. I felt obligated to stay by the patient's side as if fulfilling a debt owed for my absence at that important time. Offering companionship to the patient was the very least I could do.Working as medical interpreters and interacting with patients in varied life and health circumstances will expose us to a wide range of emotions. As we gain experience, helping patients teaches us humility and cultivates a stronger sense of empathy. Although not explicitly outlined in the standards of practice, we have the choice to utilize the powerful virtues of compassion and kindness to positively impact the life of a struggling patient. However, we also run the risk of becoming emotionally detached and losing the ability to act with compassion over time.Alongside my on-site commitments, I also work remotely for an organization managing a high volume of calls in numerous languages. In this role, medical consultations occur via phone or video. This environment can make you feel somewhat isolated, reminiscent of working in a call center where strict protocols dictate the ways calls begin and end. In this setting, I am exposed to slightly different emotional challenges. Shielded by a screen and physical distance, I often feel disconnected when interpreting, even for highly emotional situations.Yet, some interactions are hard to forget. I vividly remember a recent call during which I had to interpret for a victim of sexual assault. I felt deeply moved by their distraught voice and frightening details. For me, as an interpreter, the challenge became even more difficult as it was unreasonable to request the other party articulate their thoughts in short segments for effective communication. To keep up with the speaker, I had to jump into simultaneous interpreting, which many interpreters, including myself, find difficult. At the same time, I was slowed down by the police officer taking meticulous notes. I sympathized with the speaker but was also becoming impatient and angry with myself for experiencing these conflicting emotions. I wanted this call to end as soon as possible because it was...

In lieu of an abstract, here is a brief excerpt of the content:A THOMISTIC ANALYSIS OF THE GAIA HYPOTHESIS: HOW NEW IS THIS NEW LOOK AT LIFE ON EARTH? LAURA LANDEN, 0.P. Providence College Providence, Rhode Island W:HAT IS THE Gaia hypothesis? A recent article in Time magazine mentions the first major scientific conerence on Gaia, sponsored by the American Geophysical Union in 1988.1 The scientists ended their meeting by giving James Lovelock an exuberant standing ovation. Lovelock 's book Gaia: (...) A New Look at Life on Earth, first published in 1979, is now in its second edition.2 James E. Lovelock, British atmospheric chemist, introduced the Gaia hypothesis in 1975. This hypothesis emerged from his comparison of the chemical composition of Earth's atmosphere with the atmospheres of Venus and Mars. He found the contrast striking: Earth's atmosphere, hospitable to life, is markedly unlike the atmospheres of her two closest neighbors, Venus and Mars, both considered lifeless. Unsatisfied with mere chance as an explanation of this difference, Lovelock attributed a kind of active influence on the atmosphere by the whole of living organisms (called the biosphere) to effect conditions favorable for life. The following is taken from Lovelock's initial article on Gaia in 1975 : 1 Eugene Linden, "How the Earth Maintains Life," Time, November 13, 1989, p. 114. 2 See James E. Lovelock, Gaia: A New Look at Life on Earth (New York: Oxford University Press, 1987). Lovelock has published more recent work on Gaia. See James E. Lovelock, The Ages of Gaia: A Biography of Our Living Earth (New York: Bantam Books, 1990). 1 2 LAURA LANDEN, O.P. It appeared to us that the Earth's biosphere is able to control at least the temperature of the Earth's surface and the composition of the atmosphere. Prima facie, the atmosphere looked like a contrivance put together co-operatively by the totality of living systems to carry out certain necessary control functions. This led to the formulation of the proposition that living matter, the air, the oceans, the land surface were parts of a giant system which was able to control temperature, the composition of the air and sea, the pH of the soil and so on as to be optimum for survival of the biosphere. The system seemed to exhibit the behaviour of a single organism, even a living creature. One having such formidable powers deserved a name to match it; William Golding, the novelist, suggested Gaia-the name given by the ancient Greeks to their Earth goddess.• In this paper I present some of the factual evidence for the Gaia hypothesis and identify the underlying concepts of this position. Next, I note some reasons the hypothesis has encountered objections within the scientific community. Finally, I look to Aristotle and to Thomas Aquinas, as commentator, for insight as to how these apparent contrasts might find resolution. The factual evidence for Lovelock's claim lies in known measurements about the atmospheres of Venus, Earth, and Mars. In addition, he was able to construct a mathematical model of an abiological Earth. The following comparisons are of interest : GASES. PLANETS Lifeless Actual Venus Earth Mars Earth Carbon Dioxide 96.5% 98% 95% 0.03% Nitrogen 3.5% 1.9% 2.7% 79% Oxygen trace 0.0% 0.13% 21% Surface Temp °C 459 240to -53 13 340 aJames E.

Nitrogen and oxygen, both highly reactive gases, are essential to life as we know it. When he first proposed the Gaia hypothesis, Lovelock himself may not have been aware of the ancient roots of the concept of earth, even the universe, as a living organism. J. Donald Hughes has traced this ancient view among the Greeks and Romans, noting the following progression : First, the Earth is the oldest goddess, supporter and nurturer of her children, human and non-human, and therefore entitled to respect and worship.... Second, the Earth is a living being of whom humans are only part. Right relationship with the Earth means that the total organism is... (shrink)

Oxygen is a key regulator of both development and homeostasis and a promising candidate to bridge the influence of the environment and the evolution of new traits. To clarify the various ways in which oxygen may modulate embryogenesis, its effects are reviewed at distinct organizational levels. First, the role of pathways that sense dioxygen levels and reactive oxygen species are reviewed. Then, the effects of microenvironmental oxygen on metabolism, stemness, and differentiation throughout embryogenesis are discussed. Last, (...) the interplay between ecology and development are reexamined with a focus on the evolution of tetrapods, including during the emergence of a novel mechanism that shapes amniote limbs—interdigital cell death. Both genetic and environmental components work together during the formation of organisms, highlighting the importance of a multidisciplinary approach for understanding the evolution of new traits.

Reactive oxygen species (ROS) are highly reactive molecules produced in cells. So far, they have mostly been connected to diseases and pathological conditions. More recent results revealed a somewhat unexpected role of ROS in control of developmental processes. In this review, we elaborate on ROS in development, focussing on their connection to epithelial tissue morphogenesis. After briefly summarising unique characteristics of epithelial cells, we present some characteristic features of ROS species, their production and targets, with a focus on proteins (...) important for epithelial development and function. Finally, we provide examples of regulation of epithelial morphogenesis by ROS, and also of developmental genes that regulate the overall redox status. We conclude by discussing future avenues of research that will further elucidate ROS regulation in epithelial development. (shrink)

Reactive oxygen species (ROS) are known as toxic metabolic products in plants and other aerobic organisms. An elaborate and highly redundant plant ROS network, composed of antioxidant enzymes, antioxidants and ROS-producing enzymes, is responsible for maintaining ROS levels under tight control. This allows ROS to serve as signaling molecules that coordinate an astonishing range of diverse plant processes. The specificity of the biological response to ROS depends on the chemical identity of ROS, intensity of the signal, sites of production, (...) plant developmental stage, previous stresses encountered and interactions with other signaling molecules such as nitric oxide, lipid messengers and plant hormones. Although many components of the ROS signaling network have recently been identified, the challenge remains to understand how ROS-derived signals are integrated to eventually regulate such biological processes as plant growth, development, stress adaptation and programmed cell death.

The phenomenology of atmospheres is recently gaining attention in debates on situated affectivity. Atmospheres are defined as holistic affective qualities of situations that integrate disparate affective forces into an identifiable and unitary gestalt. They point to a blurred, pathic, relational, and pre-individual form of experience which has been described in terms of ecological affordances. Despite its relevance in diverse areas of research such as architecture, phenomenological psychiatry and aesthetics, a thorough analysis of the phenomena of affective atmospheres from an enactive-ecological (...) perspective is missing in the literature. This article aims at clarifying how and to what extent affective atmospheres can be accommodated into ecological-enactive understandings of the environment in terms of affordances. To do so, I review four perspectives on ecological affordances – the gibsonian account, the relational account, affective affordances, and the Skill Intentionality Framework (SIF) – and contrast them with the ontological and epistemológical principles that ground the phenomenology of atmospheres. I argue that only the field perspective developed in SIF is compatible with the phenomenology of atmospheres. From this perspective, affective atmospheres can be understood as phenomenological counterparts of context sensitivity, that is, as the holistic and pathic background feelings that make certain affordances more salient than others. As a conclusion, the analysis in this article shows the potential of the phenomenology of atmospheres to enrich the ecological-enactive cognition framework. It also highlights the opportunity to construct a situated understanding of affectivity that is informed by phenomenological perspectives. (shrink)

The respiration of oxygen, while essential to aerobic organisms for the generation of energy, leads to the formation of reactive oxygen intermediates (ROIs) as harmful byproducts. ROIs damage nucleic acids, lipids and proteins. Therefore, protective mechanisms against elevated intracellular ROI levels, referred to as oxidative stress, have evolved. These include the activation of transcription factors which elevate the expression of protective enzymes. Eukaryotic cells have also evolved the ability to specifically generate ROIs are used as second messengers to (...) activate gene expression. Here we will discuss both prokaryotic and eukaryotic transcription factors that respond to ROIs. In addition, transcription factors will be described that are activated by either exposure to antioxidants, which reduce the intracellular ROI concentration, or by hypoxia, the absence of oxygen.

The influence of sediment oxygen heterogeneity, due to bioturbation, on diffusive oxygen flux was investigated. Laboratory experiments were carried out with 3 macrobenthic species presenting different bioturbation behaviour patterns: the polychaetes Nereis diversicolor and Nereis virens, both constructing ventilated galleries in the sediment column, and the gastropod Cyclope neritea, a burrowing species which does not build any structure. Oxygen two-dimensional distribution in sediments was quantified by means of the optical planar optode technique. Diffusive oxygen fluxes and (...) a variability index were calculated on the captured oxygen images. All species increased sediment oxygen heterogeneity compared to the controls without animals. This was particularly noticeable with the polychaetes because of the construction of more or less complex burrows. Integrated diffusive oxygen flux increased with oxygen heterogeneity due to the production of interface available for solute exchanges between overlying water and sediments. This work shows that sediment heterogeneity is an important feature of the control of oxygen exchanges at the sediment–water interface. (shrink)

Although the generation of reactive oxygen species is an activity normally associated with phagocytic leucocytes, mammalian spermatozoa were, in fact, the first cell type in which this activity was described. In recent years it has become apparent that spermatozoa are not the only nonphagocytic cells to exhibit a capacity for reactive oxygen species production, because this activity has been detected in a wide variety of different cells including fibroblasts, mesangial cells, oocytes, Leyding cells endothelial cells, thryroid cells, adipocytes, (...) tumour cell and platelets. Since the capacity to generate reactive oxygen species is apparently so widespread, the risk‐benefit equation for these potentially pernicious molecules becomes a matter of intese interest. In the case of human spermatozoa, the risk of manufacturing reactive oxygen metabolites is considerable because these cells are particularly vulnerable to lipid peroxidation. Indeed, there is now good evidence to indicate that oxygen radicals are involved in the initiation of peroxidative damage to the sperm plasma membrane, seen in many cases of male infertility. This risk is off‐set by recent data suggesting that superoxide anions and hydrogen peroxide also participate in the induction of key biological events such as hyperactiavated motility and the acrosome reaction. Thus, human spermatozoa appear to use reactive oxygen species for a physiological purpose and have the difficult task of ensuring the balanced generation of these potentially harmful, but biologically important, modulators of cellular function.

Dans cet article ici en traduction inédite, dont la première version allemande date de 2011, Hermann Schmitz s’interroge sur les éléments qui, se déployant dans l’interaction entre les édifices et la vie sensible et affective des habitants, constituent l’atmosphère d’une ville. Dans cette perspective, il met à contribution plusieurs grands concepts de sa philosophie (la « Nouvelle Phénoménologie » développée dès les années 1960), destinée à élucider l’expérience vécue involontaire : dynamique du corps de chair (Leib), suggestions de mouvements, caractères (...) synesthésiques.

Unusual atmospheric phenomena (UAPs) were observed in daylight by multiple observers on board two civil aircraft in widely separated locations. We summarise results of an investigation based on radio communications reporting events in real time to Air Traffic Control (ATC), ATC radar and weather radar recordings, Civil Aviation Authority (CAA) documents, witness interviews and statements, and other sources. We describe attempts to explain the phenomena with the help of expert specialist advisers and professional resources in the fields of meteorology, atmospheric (...) optics, oceanography and geophysics. We are able to show that widespread media stories describing enormous phenomena up to a mile wide and detected by radar were based on speculation and misunderstandings. Many news reports were grossly exaggerated and inaccurate. However, we are unable to conclusively identify the UAPs observed. It proves possible to eliminate a number of theories with a fairly high level of confidence, leaving us with two types of phenomena—a rare atmospheric-optical effect or an earthquake precursor—both of which have the potential to explain at least some, although not all, features of the reports. We highlight certain features that appear to leave open the possibility of unusual physical processes. Keywords: UAP—atmospheric optics—anomaly—mirage—earthquake lights—EQL. (shrink)

The new phenomenological and aesthetic paradigm of atmospheres, conceived as feelings spread out in the external space and not as private moods, is tested here from different points of view and different disciplines in the context of a full valorization of the so-called "affective turn" in Humanities.

Introduction of O2 to Earth's early biosphere stimulated remarkable evolutionary adaptations, and a wide range of electron acceptors allowed diverse, energy-yielding metabolic pathways. Enzymatic reduction of O2 yielded a several-fold increase in energy production, enabling evolution of multi-cellular animal life. However, utilization of O2 also presented major challenges as O2 and many of its derived reactive oxygen species are highly toxic, possibly impeding multicellular evolution after the Great Oxidation Event. Remarkably, ROS, and especially hydrogen peroxide, seem to play a (...) major part in early diversification and further development of cellular respiration and other oxygenic pathways, thus becoming an intricate part of evolution of complex life. Hence, although harnessing of chemical and thermo-dynamic properties of O2 for aerobic metabolism is generally considered to be an evolutionary milestone, the ability to use ROS for cell signaling and regulation may have been the first true breakthrough in development of complex life. The importance of Earth's oxygen cycle and reactive oxygen species produced on the evolution of complex life. The ability to detoxify oxygen species is not a trait that emerged as a response to increased O2 levels but rather crucial adaptation to the early Earth's weakly oxic microenvironments. (shrink)

When the policies and activities of one country or generation harm both other nations and later generations, they constitute serious injustices. Recognizing the broad threat posed by anthropogenic climate change, advocates for an international climate policy development process have expressly aimed to mitigate this pressing contemporary environmental threat in a manner that promotes justice. Yet, while making justice a primary objective of global climate policy has been the movement's noblest aspiration, it remains an onerous challenge for policymakers. -/- Atmospheric Justice (...) is the first single-authored work of political theory that addresses this pressing challenge via the conceptual frameworks of justice, equality, and responsibility. Throughout this incisive study, Steve Vanderheiden points toward ways to achieve environmental justice by exploring how climate change raises issues of both international and intergenerational justice. In addition, he considers how the design of a global climate regime might take these aims into account. Engaging with the principles of renowned political philosopher John Rawls, he expands on them by factoring in the needs of future generations. Vanderheiden also demonstrates how political theory can contribute to reaching a better understanding of the proper human response to climate change. By showing how climate policy offers insights into resolving contemporary controversies within political theory, he illustrates the ways in which applying normative theory to policy allows us to better understand both. -/- Thoroughly researched and persuasively argued, Atmospheric Justice makes an important step toward providing us with a set of carefully elaborated first principles for achieving environmental justice.

In forming the international regime on climate change, commodification of the atmosphere has become the primary mechanism around which policy formulation is being organized. This has been an outcome of the dominance of anthropocentric and ethnocentric values in the discourse represented by the negotiations around the Framework Convention on Climate Change. Environmentalism offers an alternative value system from which a critique of the emerging global climate change management regime can be undertaken. This critique makes clear both the inadequacy of (...) economic approaches based on commodification of the atmosphere to protect the global environment and the need to include a variety of actors, values, and approaches in the climate change policy debate.

The atmosphere is critical to climate change. It can amplify shifts in the climate system, and also mitigate them. Giving readers an overview of key atmospheric processes, the author of this book looks at how our climate system receives energy from the sun and sheds it by emitting infrared radiation back into space. The atmosphere regulates these radiative energy flows and transports energy through weather systems such as thunderstorms, monsoons, hurricanes, and winter storms. The author explains how these (...) processes work, and also how precipitation, cloud formation, and other phase changes of water strongly influence weather and climate. He discusses how atmospheric feedbacks affect climate change, how the large-scale atmospheric circulation works, how predicting the weather and the climate are fundamentally different challenges, and much more.

This chapter traces the genealogy of the term atmosphere in the German language, identifies historical semantic shifts, and points to its grammatical specifics. The state of research on atmospheres is briefly summarized and an overview is offered of the various definitions of the term in different disciplines. Drawing on Timothy Morton’s theory of ambient poetics, and on Hermann Schmitz’s “new phenomenology,” four key characteristics of atmospheres are discussed and elaborated: their mereological constitution, their modal structure, their intensification at affective (...) thresholds, and their affective efficacy through suggestions of movement.

In 1983, the British police adopted their first public order policing manual, laying the foundations of a secretive archive. The manuals and training materials produced in the intervening years provide an untapped repository of affective thought. This article reads the 1983 and 2016 training materials for their atmospheric insights. It develops the term police ‘atmotechnics’ to describe interventions that are specifically designed to affect the crowded atmosphere of protest or other disorder. The manuals reveal a gradual shift from interventions (...) designed to evince fear and awe, to ones that seek to calm crowds. But more importantly, they underline a shift from a linear understanding of atmotechnics (as a prelude to ‘the use of force’), to an affective feedback loop where specialised officers are deployed to ‘sense’ mood changes among crowds, allowing senior strategic and tactical decisions to take account of atmospheric conditions.

There is fast-growing awareness of the role atmospheres play in architecture. Of equal interest to contemporary architectural practice as it is to aesthetic theory, this 'atmospheric turn' owes much to the work of the German philosopher Gernot Böhme. Atmospheric Architectures: The Aesthetics of Felt Spaces brings together Böhme's most seminal writings on the subject, through chapters selected from his classic books and articles, many of which have hitherto only been available in German. This is the only translated version authorised by (...) Böhme himself, and is the first coherent collection deploying a consistent terminology. It is a work which will provide rich references and a theoretical framework for ongoing discussions about atmospheres and their relations to architectural and urban spaces. Combining philosophy with architecture, design, landscape design, scenography, music, art criticism, and visual arts, the essays together provide a key to the concepts that motivate the work of some of the best contemporary architects, artists, and theorists: from Peter Zumthor, Herzog & de Meuron and Juhani Pallasmaa to Olafur Eliasson and James Turrell. With a foreword by Professor Mark Dorrian and an afterword by Professor David Leatherbarrow,, the volume also includes a general introduction to the topic, including coverage of it history, development, areas of application and conceptual apparatus.

Two recent lines of inquiry that have emerged in educational philosophy and research are the turn to affect theory and the call for decolonising education. Although there have been some efforts to bring these two lines of inquiry together and inform educational philosophy and research, there is still important conceptual work to be done, especially in the context of peace education, our focus in this paper. To initiate this work, we consider the concepts of affective atmospheres and atmospheric attunements that (...) have been discussed within the context of affect theory. Drawing on these two concepts, we argue that fundamental to any attempts to decolonising peace education is elucidating the coloniality of affects. This is a necessary step towards dismantling the colonial affects that permeate peace education praxis and are maintained through perceptions of peace and conflict embedded within a Western, Eurocentric frame. The paper analyses the theoretical insights emerging from bringing these concepts together to bear on the decolonisation of peace education and discusses some political possibilities that are also enabled.

Through an atmospherological approach, primarily inspired by the Aisthetik and the New Phenomenology, the paper investigates the relationship between atmosphere and lived space, defines what kind of perception the atmospheric one is and examines the space we experience in the lifeworld and to which plane geometry turns out to be completely blind. Sketching briefly the history of lived space, we assume that atmospheres function as affordances that permeate the lived space, i.e. as ecological invites or meanings that are ontologically (...) rooted in things and quasi-things.

Initially conceived as an interview with the hybrid media artist Brian Goeltzenleuchter, this text gradually took the form of a conversation on various issues regarding olfactory art and the aesthetic significance of smell. Framing the artistic uses of odours in the context of contemporary art, the paper discloses some of its foundational traits, variations, and underlying impulses. By commenting on Goeltzenleuchter’s olfactory artworks through a philosophical perspective, this contribution covers a number of subjects including the notion of atmosphere, the (...) socio-cultural values and narratives conveyed by scents, the suggestive relationship between spaces and aromas, and the phenomenology of smells as compared to the experience of sounds. Consistent with how smell perception unfolds, the dialogue flows in a form that is not rigidly structured but airy, ephemeral, and fluid, developing a sequence of insights whose aim is, rather than scrutinising a specific topic, to evoke the essence of olfactory poetics as a whole.

A growing number of lay Buddhist practitioners have sought out alternative ways to incorporate Buddhist teachings in their daily practices and make positive changes in society by “doing good” for others. Sometimes recognized as part of “humanistic Buddhism,” this approach emphasizes general morality and focuses on people who need help as a way to fulfill Buddhist teachings in this world. Some Chinese Buddhist practitioners who follow the Tibetan Buddhist tradition also carry out similar humanistic engagements but use more subtle space-making (...) processes and often “brand” these as Buddhist practices. Drawing on the ethnographic observations of lay Buddhist practitioners in urban China, this article examines how urban practitioners promote (middle-class) morality and well-being lifestyles through what I call “atmospheric Buddhism.” Ultimately, the article argues that an alternative mode of Buddhist practice is emerging in Chinese urban environments in order to cope with politically constrained environments.

In 1934, Karl N. Llewellyn published a lively essay trumpeting the dawn of legal realism, "On Philosophy in American Law." The charm of his defective little piece is its style and audacity. A philosopher might be seduced into reading Llewellyn’s essay by its title; but one soon learns that by "philosophy" Llewellyn only meant "atmosphere". His concerns were the "general approaches" taken by practitioners, who may not even be aware of having general approaches. Llewellyn paired an anemic concept of (...) philosophy with a pumped-up conception of law. Llewellyn’s "law" included anything that reflects the "ways of the law guild at large" - judges, legislators, regulators, and enforcers. Llewellyn argued that the legal philosophies implicit in American legal practice had been natural law, positivism and realism, each adopted in response to felt needs of a time. We must reckon with many other implicit "philosophies" to understand the workings of the law guild, not the least of which has been racism. Others, maternalism and paternalism, my foci here, persist in American law, despite women’s progress toward equality. Both maternalism and paternalism were strikingly present in a recent decision of the U.S. Supreme Court, Gonzales v. Carhart, upholding the federal Partial-Birth Abortion Ban Act. (shrink)

Paintings can exert a strong effect on their viewers by creating atmospheres. But how is it possible for a painting to create an atmosphere? My goal in this paper is to provide a partial answer to this question by focusing on the depiction of light. I argue that paintings can elicit experiences of atmospheres in part because they can depict pictorial space as filled with ambient light that has a distinctive phenomenal character. It is in virtue of this distinctive (...) phenomenal character that the depicted ambient light can make a significant contribution to the overall phenomenal character of the experienced atmosphere.

This book provides a presentation of the concept of “atmosphere” in the realm of aesthetics. An “atmosphere” is meant to be an emotional space. Such idea of “atmosphere” has been more and more subsumed by human and social sciences in the last twenty years, thereby becoming a technical notion. In many fields of the Humanities, affective life has been reassessed as a proper tool to understand the human being, and is now considered crucial. In this context, the (...) link between atmospheres and aesthetics becomes decisive. Nowadays, aesthetics is no longer only a theory of art, but has recovered its original vocation: to be a general theory of perception conceived of as an ordinary experience of pre-logical character. In its four parts, this volume discusses whether atmospheres could take the prominent and paradigmatic position previously held by art in order to make sense of such sensible experience of the world.

L’atmosphère« Atmosphère » est un terme employé communément par des auteurs dans le domaine de l’esthétique que dans celui de la météorologie. Ils le comprennent pourtant de manière assez différente, chacun prétendant que leur emploi est la plus fondamentale et que l’autre est seulement métaphorique. Pour les esthéticiens, l’atmosphère réelle est une aura qui émane des choses et qui affecte nos humeurs et nos motivations; pour les météorologistes, il s’agit de l’enveloppe gazeuse qui entoure la planète. Je montre que les (...) deux sens excluent l’air ou le réduisent à un éther immatériel. D’une part, pour la science météorologique, tout se passe comme l’air était enfermé à l’intérieur et considéré comme un ensemble d’effets mesurables et calculables. D’autre part,l’esthétique de l’affect a relié l’atmosphère aux formes solides des artéfacts et des paysages. En ramenant le medium aérien, je cherche une signification de l’atmosphère qui transcende l’opposition entre l’affectif et le météorologique. Je le fais en suivant Merleau-Ponty, qui traite l’atmosphère comme un espace d’inspiration et d’expiration. En tant que tel, il correspond étroitement à ce que Merleau-Ponty lui-même appelle la « chair ». Ce concept pourrait aussi être traduit par « meshwork » (réseau/filet/grillage), référant à ces faisceaux de lignes et de chemins par lesquels chaque être humain est cousu à la fabrique du monde. Pour Merleau-Ponty, la portée de la notion de chair réside dans l’affirmation que la perception est fondamentalement réversible. On ne peut être sentant que dans un monde sentant; c’est pourquoi, comme il le soutient, notre perception des choses dans l’environnement répond à la perception par l’environnementde notre soi. Cependant, je soutiens au contraire que ces deux mouvements d’inspiration et d’expiration ne sont pas le contraire exact l’un de l’autre. Comme le mouvement de la brasse en nataion, le premier est un mouvement de rassemblement et le second de propulsion. Nous inhalons l’atmosphère, mais nous exhalons selon les lignes du réseau. Bref, réseau et atmosphère sont deux côtés de la chair, et c’est dans leur alternance rythmique que nous trouvons la relation entre les lignes et le temps météorologique, qui est, comme je le soutiens, fondamental à la vie.L’atmosfera‘Atmosfera’ è una parola usata comunemente tanto da chi scrive di estetica come dai metereologi. Ciononostante, essi intendono con ciò delle cose piuttosto differenti, ognuno ritenendo che il proprio e il senso più fondamentale mentre l’altrui è meramente metaforico. Per chi si occupa di estetica, l’atmosfera reale è un’aura che emana dalle cose e affetta il nostro umore e le nostre motivazioni; per i metereologi è l’involucro gassoso che circonda il pianeta. Mostro come entrambi i sensi trascurano l’aria, o la riducono a un etere immateriale. Da una parte, per la scienza metereologica, è come se l’aria fosse stata portata al chiuso e presentata come una serie di effetti misurabili e calcolati. Dall’altra, l’estetica dell’affetto ha legato l’atmosfera alle forme solide degli artefatti e dei paesaggi.Nel reintrodurre l’ambiente aereo, intendo trovare un significato di atmosfera che trascenda l’opposizione tra i sensi affettivo e meteorologico. Faccio questo, seguendo Merleau-Ponty, trattando l’atmosfera come uno spazio di inalazione e esalazione. Come tale, corrisponde da vicino a ciò che Merleau-Ponty stesso chiama “la carne”. Ma questo concetto potrebbe anche essere tradotto come ‘reticolo’ (meshwork), riferendosi a quei grovigli di linee e percorsi lungo i quali ogni essere vivente è cucito al tessuto del mondo. Per Merleau-Ponty, il significato della carne risiede nella sua affermazione secondo la quale la percezione è fondamentalmente reversibile. Si può essere senzienti soltanto in un mondo senziente; quindi, ritiene il filosofo, la nostra percezione delle cose nell’ambienteè ricambiata dalla percezione che quest’ultimo ha di noi. Io mostro, al contrario, che questi due movimenti, corrispondenti all’inalazione e all’esalazione, non sono l’esatto rovescio l’uno dell’altro. Come nella bracciata a stile libero nel nuoto, il primo è un movimento di raccolta, il secondo un movimento di propulsione. Ovverossia, inaliamo l’atmosfera, ma esaliamo secondo le linee del reticolo. In breve, il reticolo e l’atmosfera sono due facce della carne, e troviamo nella loro alternanza ritmica la relazione tra le linee e il tempo che, come sostengo, è fondamentale alla vita. (shrink)

As a contemporary form of aesthetics of nature, Eco-aesthetics is dedicated to an aesthetic revision of the split between humans and nature in the process of modernization. Starting from the criticism that the current eco-aesthetic research is usually limited to a taste evaluation of natural beauty and that many studies pay little attention to practically reconstructing a new harmony between humans and nature under contemporary conditions, the article focuses on the following issue: a) To what extent can the approach of (...) Eco-aesthetics be theoretically re-formulated so that the perspective of traditional aesthetics of judgment, predominantly fixed on the experience and reflection of natural beauty, can be avoided? b) How can this reformulation contribute to recultivating and renaturing an environment in a widely urbanized world? Here the concept of ‘atmosphere’ which has been primarily developed by contemporary German philosophers emphasizes the interaction between bodily perception and the qualities of the surrounding environment is of particular significance for solving these issues. It is demonstrated that in atmospheric experiences the body embeds man, together with his multifarious ways of perception and sense experiences, into nature so that man and nature are interrelated with each other and merged into a unified whole. The eco-aesthetic meaning here transcends the framework of the beauty of nature and is characterized by an infinite range of perceptual possibilities towards the integration of the human situation and the environmental conditions. At the same time, the investigation of the conditions and forms of atmospheric creation will contribute to further extending the eco-aesthetic vision to the practical area. And it is not least this practical dimension that distinguishes the Eco-aesthetics from traditional aesthetic approaches to nature. (shrink)
