    M. Katičić Holism in Deep Ecology and Gaia-Theory: A Contribution to Eco-Geological... ISSN 1848-0071 UDC 171+179.3=111 Recieved: 2013-02-25 Accepted: 2013-03-25 Original scientific paper HOLISM IN DEEP ECOLOGY AND GAIA-THEORY: A CONTRIBUTION TO ECO-GEOLOGICAL SCIENCE, A PHILOSOPHY OF LIFE OR A NEW AGE STREAM? MARINA KATINIĆ Faculty of Humanities and Social Sciences, University of Zagreb, Croatia e-mail: [email protected] In the second half of 20th century three approaches to phenomenon of life and environmental crisis relying to a holistic method arose: ecosophy that gave impetus to the deep ecology movement, Gaia-hypothesis that evolved into an acceptable scientific theory and gaianism as one of the New Age spiritual streams. All of this approaches have had different methodologies, but came to analogous conclusions on relation man-ecosystem. The goal of the paper is to introduce the three approaches' theoretical and practical outcomes, compare them and evaluate their potency to stranghten responsibility of man towards Earth ecosystem which is a self-regulating whole which humanity is part of. Key words: holism, ecosophy, deep ecology movement, gaia-theory, new age, responsibility. Holizam u dubinskoj ekologiji i teoriji Geje: doprinos ekogeološkoj znanosti, filozofija života ili struja New agea? U drugoj polovici 20. stoljeća pojavila su se tri pristupa fenomenu života i ekološkoj krizi s osloncem u holističkoj metodi: ekozofija koja je dala poticaj razvoju pokreta dubinske ekologije, hipoteza Geje koja se razvila u prihvatljivu znanstvenu teoriju i gajanizam kao jedna od New Age duhovnih struja. Ova su se tri pristupa služila različitim metodama, no došla su do analognih zaključaka o odnosu čovjek-ekosustav.

  • Earth Science Education As a Key Component of Education for Sustainability
    sustainability Review Earth Science Education as a Key Component of Education for Sustainability Clara Vasconcelos 1,* and Nir Orion 2,* 1 Interdisciplinary Centre of Marine and Environmental Research (CIIMAR), Science Teaching Unit (UEC) & Department of Geosciences, Environment and Spatial Planning (DGAOT), Faculty of Sciences (FCUP), University of Porto, 4169-007 Porto, Portugal 2 Science Teaching Department, Weizmann Institute of Science, Rehovot 7610001, Israel * Correspondence: [email protected] (C.V.); [email protected] (N.O.); Tel.: +97-289-344-043 (C.V.); +220-402-462 (N.O.) Abstract: Environmental insight has emerged as a new scientific concept which incorporates the understanding that the Earth is made up of interworking subsystems and the acceptance that humans must act in harmony with the Earth’s dynamic balanced cycle. This Earth system competency represents the highest level of knowing and understanding in the geosciences community. Humans have an important role as participative beings in the Earth’s subsystems, and they must therefore acknowledge that life on Earth depends on a geoethically responsible management of the Earth system. Yet, the world is far from achieving sustainable development, making the role of the Earth science education in promoting education for sustainability even more relevant. The Earth system approach to education is designed to be an effective learning tool for the development of the innovative concept of environmental insight. Through a holistic view of planet Earth, students realize that humans have the ability to enjoy a sustainable life on our planet while minimising detrimental environmental impacts. There is growing evidence that citizens value science and need to be informed about Earth system problems such as climate change, resource efficiency, pandemics, sustainable use of water resources, and how to protect bio-geodiversity.

Time to act: Understanding earth system governance and the crisis of modernity. Earth System Governance Working Paper No. 19. Lund and Amsterdam: Earth System Governance Project. All rights remain with the authors. Authors' Contact: Roberto Pereira Guimarães, [email protected] Working Paper Series Editor Ruben Zondervan Executive Director Earth System Governance Project ([email protected]) Abstract Despite the frequent calls for action, decisions and agreements made at successive international conferences, the levels of socio-environmental unsustainability have increased considerably over the past decades. The changes in the global environment have reached a point at which they seriously threaten human security and the ecological and social pillars of modern civilization. In short, the globalization of the environmental crisis compels us to acknowledge that the history of humankind is in fact inexorably entwined with the history of its relationships with nature. We, therefore, analyzed the human dimensions associated with global environmental change in order to propose a new paradigm for the current society. We also demonstrate the main factors described by Jared Diamond (2006) that the past societies used to overcome the negative tendencies and threats that had put these communities’ very survival at risk. After this, we associate them with the new ethical- political challenges that the financial crisis in the first decade of the 21st century has brought to the international agenda and its relationship with the institutions’ inability to act regarding global environmental change.

  • Alexander Von Humboldt's Legacy in Earth System Science
    EGU21-16439 https://doi.org/10.5194/egusphere-egu21-16439 EGU General Assembly 2021 © Author(s) 2021. This work is distributed under the Creative Commons Attribution 4.0 License. Alexander von Humboldt’s legacy in Earth System Science Manfred R. Strecker University of Potsdam, Structural Geology, Potsdam, Germany ([email protected]) In this lecture I will first review some of Alexander von Humboldt’s studies on the importance of vertical and latitudinal temperature gradients and surface processes in the context of mountain building and thereby highlight his seminal contributions to Earth System Science. In a second step I will briefly comment on his influence beyond science, including public outreach and the general public’s Earth science literacy – in the face of fake news and distrust in scientific method and discourse, an issue more timely than ever. The past decades have witnessed a radical shift in human perception of Earth and nature; climate change and increased competition for natural resources combined with human vulnerability to natural hazards have moved environmentalism from the fringes of public awareness to governmental policies. This shift in awareness was presaged by paradigmatic shifts in Earth Science leading to the modern view of Earth as a dynamic system of interactive physical, chemical and biological processes, and ultimately to establishment of the integrative field of Earth System Science. To a certain extent, this point of view and the realization that research across disciplinary boundaries is important and necessary to understand geoprocesses at a variety of time and length scales and in the context of linkages between the different spheres was already the fundament of Humboldt’s thinking and research philosophy during the first half of the 19th century: "The principal impulse by which I was directed was the earnest endeavor to comprehend the phenomena of physical objects in their general connection, and to represent nature as one great whole."

James Lovelock’s Gaia hypothesis: "A New Look at Life on Earth" ... for the Life and the Earth sciences. Sébastien Dutreuil James Lovelock (b. 1919) was described by the curators of an exhibition at London’s Science Museum in 2014 as a "scientist, inventor and maverick."1 He was clearly an eclectic inventor from the very beginning of his career as a research engineer in the 1940’s. He was an accomplished scientist before formulating the Gaia hypothesis in the 1970’s, with pioneering work in analytical chemistry, biochemistry and cryobiology. He was perhaps a maverick, when he quit academia in 1964, at age 45 to settle as an "independent scientist." But the Gaia hypothesis, his major accomplishment, is that of a dreamer.
