Spiritual ecology is an emerging field in religion, conservation, and academia recognizing that there is a spiritual facet to all issues related to conservation, environmentalism, and earth stewardship. Proponents of Spiritual Ecology assert a need for contemporary conservation work to include spiritual elements and for contemporary religion and spirituality to include awareness of and engagement in ecological issues.
Contributors in the field of Spiritual Ecology contend there are spiritual elements at the root of environmental issues. Those working in the arena of Spiritual Ecology further suggest that there is a critical need to recognize and address the spiritual dynamics at the root of environmental degradation.
The field is largely emerging through three individual streams of formal study and activity: science and academia, religion and spirituality, and ecological sustainability.
Despite the disparate arenas of study and practice, the principles of spiritual ecology are simple: In order to resolve such environmental issues as depletion of species, global warming, and over-consumption, humanity must examine and reassess our underlying attitudes and beliefs about the earth, and our spiritual responsibilities toward the planet. U.S. Advisor on climate change, James Gustave Speth, said: "I used to think that top environmental problems were biodiversity loss, ecosystem collapse and climate change. I thought that thirty years of good science could address these problems. I was wrong. The top environmental problems are selfishness, greed and apathy, and to deal with these we need a cultural and spiritual transformation."
Thus, it is argued, ecological renewal and sustainability necessarily depends upon spiritual awareness and an attitude of responsibility. Spiritual Ecologists concur that this includes both the recognition of creation as sacred and behaviors that honor that sacredness.
Recent written and spoken contributions of Pope Francis, particularly his May 2015 Encyclical, Laudato si', as well as unprecedented involvement of faith leaders at the 2015 United Nations Climate Change Conference in Paris reflect a growing popularity of this emerging view. The UN secretary general, Ban Ki-moon, stated on Dec 4, 2015, that “Faith communities are vital for global efforts to address the climate challenge. They remind us of the moral dimensions of climate change, and of our obligation to care for both the Earth’s fragile environment and our neighbours in need.” 
Spiritual ecology identifies the Scientific Revolution -- beginning the 16th century, and continuing through the Age of Enlightenment to the Industrial Revolution -- as contributing to a critical shift in human understanding with reverberating effects on the environment. The radical expansion of collective consciousness into the era of rational science included a collective change from experiencing nature as a living, spiritual presence to a utilitarian means to an end.
During the modern age, reason became valued over faith, tradition, and revelation. Industrialized society replaced agricultural societies and the old ways of relating to seasons and cycles. Furthermore, it is argued that the growing predominance of a global, mechanized worldview, a collective sense of the sacred was severed and replaced with an insatiable drive for scientific progress and material prosperity without any sense of limits or responsibility.
Some in Spiritual Ecology argue that a pervasive patriarchal world-view, and a monotheistic religious orientation towards a transcendent divinity, is largely responsible for destructive attitudes about the earth, body, and the sacred nature of creation. Thus, many identify the wisdom of indigenous cultures, for whom the physical world is still regarded as sacred, as holding a key to our current ecological predicament.
Spiritual ecology is a response to the values and socio-political structures of recent centuries with their trajectory away from intimacy with the earth and its sacred essence. It has been forming and developing as an intellectual and practice-oriented discipline for nearly a century.
Spiritual ecology includes a vast array of people and practices that intertwine spiritual and environmental experience and understanding. Additionally, within the tradition itself resides a deep, developing spiritual vision of a collective human/earth/divine evolution that is expanding consciousness beyond the dualities of human/earth, heaven/earth, mind/body. This belongs to the contemporary movement that recognizes the unity and interrelationship, or "interbeing," the interconnectedness of all of creation.
Visionaries carrying this thread include Rudolf Steiner (1861-1925) who founded the spiritual movement of anthroposophy, and described a "co-evolution of spirituality and nature" and Pierre Teilhard de Chardin, a French Jesuit and paleontologist (1881-1955) who spoke of a transition in collective awareness toward a consciousness of the divinity within every particle of life, even the most dense mineral. This shift includes the necessary dissolution of divisions between fields of study as mentioned above. "Science, philosophy and religion are bound to converge as they draw nearer to the whole."
Thomas Berry, the American Passionist priest known a 'geologian' (1914-2009), has been one of the most influential figures in this developing movement, with his stress on returning to a sense of wonder and reverence for the natural world. He shared and furthered many of Teillard de Chardin’s views, including the understanding that humanity is not at the center of the universe, but integrated into a divine whole with its own evolutionary path. This view compels a re-thinking of the earth/human relationship: "The present urgency is to begin thinking within the context of the whole planet, the integral earth community with all its human and other-than-human components."
More recently, leaders in the Engaged Buddhism movement, including Thich Nhat Hanh, also identify a need to return to a sense of self which includes the Earth. Joanna Macy describes a collective shift – referred to as the "Great Turning" – taking us into a new consciousness in which the earth is not experienced as separate. Sufi teacher Llewellyn Vaughan-Lee similarly grounds his spiritual ecology work in the context of a collective evolutionary expansion towards oneness, bringing us all toward an experience of earth and humanity – all life – as interdependent. In the vision and experience of oneness, the term "spiritual ecology" becomes, itself, redundant. What is earth-sustaining is spiritual; that which is spiritual honors a sacred earth.
An important element in the work of these contemporary teachers is the call for humanity’s full acceptance of responsibility for what we have done – physically and spiritually – to the earth. Only through accepting responsibility will healing and transformation occur.
Including the need for a spiritual response to the environmental crisis, Charles, Prince of Wales in his 2010 book "Harmony: A New Way of Looking at Our World," writes: "A specifically mechanistic science has only recently assumed a position of such authority in the world... (and) not only has it prevented us from considering the world philosophically any more, our predominantly mechanistic way of looking at the world has also excluded our spiritual relationship with Nature. Any such concerns get short shrift in the main stream debate about what we do to the Earth." Prince Charles, who has promoted environmental awareness since the 1980s, continues: "... by continuing to deny ourselves this profound, ancient, intimate relationship with Nature, I fear we are compounding our subconscious sense of alienation and disintegration, which is mirrored in the fragmentation and disruption of harmony we are bringing about in the world around us. At the moment we are disrupting the teeming diversity of life and the ‘ecosystems’ that sustain it—the forests and prairies, the woodland, moorland and fens, the oceans, rivers and streams. And this all adds up to the degree of ‘disease’ we are causing to the intricate balance that regulates the planet’s climate, on which we so intimately depend."
In May 2015 Pope Francis’s Encyclical, “Laudato Si’: On Care for our Common Home,” endorsed the need for a spiritual and moral response to our environmental crisis, and thus implicitly brings the subject of spiritual ecology to the forefront of our present ecological debate. This encyclical recognizes that “The ecological crisis is essentially a spiritual problem,”  in line with the ideas of this developing field. American environmentalist, author, and journalist Bill McKibben who has written extensively on the impact of global warming, says that Pope Francis has "brought the full weight of the spiritual order to bear on the global threat posed by climate change, and in so doing joined its power with the scientific order."
Scientist, environmentalist, and world leader in sustainable ecology David Suzuki also expresses the importance of including the sacred in addressing the ecological crisis: "The way we see the world shapes the way we treat it. If a mountain is a deity, not a pile of ore; if a river is one of the veins of the land, not potential irrigation water; if a forest is a sacred grove, not timber; if other species are biological kin, not resources; or if the planet is our mother, not an opportunity -- then we will treat each other with greater respect. Thus is the challenge, to look at the world from a different perspective."
Historically we see the development of the foundational ideas and perspective of spiritual ecology in mystical arms of traditional religions and spiritual arms of environmental conservation. These ideas put forth a story of an evolving universe and potential human experience of wholeness in which dualities dissipate—dualities that have marked past eras and contributed to the destruction of the earth as "other" than spirit.
A Catholic nun interviewed by Sarah MacFarland Taylor, author of the 2009 book, “Green Sisters: Spiritual Ecology” (Harvard University Press, 2009), articulates this perspective of unity: “There is no division between planting new fields and prayer.”
Many in the field of spiritual ecology agree that a distinct stream of experience threading throughout history that has at its heart a lived understanding of the principles, values and attitudes of spiritual ecology: indigenous wisdom. The term "indigenous" in this context refers to that which is native, original, and resident to a place, more specifically to societies who share and preserve ways of knowing the world in relationship to the land. For many Native traditions, the earth is the central spiritual context. This principle condition reflects an attitude and way of being in the world that is rooted in land and embedded in place. Spiritual ecology directs us to look to revered holders of these traditions in order to understand the source of our current ecological and spiritual crisis and find guidance to move into a state of balance.
Features of many indigenous teachings include life as a continual act of prayer and thanksgiving, knowledge and symbiotic relationship with an animate nature, and being aware of one’s actions on future generations. Such understanding necessarily implies a mutuality and reciprocity between people, earth and the cosmos.
The above historical trajectory is located predominantly in a Judeo-Christian European context, for it is within this context that humanity experienced the loss of the sacred nature of creation, with its devastating consequences. For example, with colonization, indigenous spiritual ecology was historically replaced by an imposed Western belief that land and the environment are commodities to be used and exploited, with exploitation of natural resources in the name of socio-economic evolution. This perspective "... tended to remove any spiritual value of the land, with regard only given for economic value, and this served to further distance communities from intimate relationships with their environments," often with "devastating consequences for indigenous people and nature around the world." However, the complicity of indigenous peoples in the Quaternary extinction event by overhunting megafauna well before European colonization in North America, South America and Australia casts doubt upon the view of indigenous wisdom promoted by those in the Spiritual Ecology movement.
Along with the basic principles and behaviors advocated by spiritual ecology, some indigenous traditions hold the same evolutionary view articulated by the Western spiritual teachers listed above. The understanding of humanity evolving toward a state of unity and harmony with the earth after a period of discord and suffering is described in a number of prophecies around the globe. These include the White Buffalo prophecy of the Plains Indians, the prophecy of the Eagle and Condor from the people of the Andes, and the Onondaga prophecies held and retold by Oren Lyons.
Spiritual ecology is developing largely in three arenas identified above: Science and Academia, Religion and Spirituality, and Environmental Conservation.
Science and academia
Among scholars contributing to spiritual ecology, five stand out because of their exceptionally high creativity, productivity and impact: Steven C Rockefeller, Mary Evelyn Tucker, John Grim, Bron Taylor and Roger S. Gottlieb.
Mary Evelyn Tucker and John Grim are the dynamic forces behind Yale University’s Forum on Religion and Ecology, an international multi-religious project exploring religious world-views, texts ethics and practices in order to broaden understanding of the complex nature of current environmental concerns.
Steven Clark Rockefeller is an author of numerous books about religion and the environment, and is professor emeritus of religion at Middlebury College. He played a leading role in the drafting of the Earth Charter.
Roger S. Gottlieb is a professor of Philosophy at Worcester Polytechnic Institute is author of over 100 articles and 16 books on environmentalism, religious life, contemporary spirituality, political philosophy, ethics, feminism, and the Holocaust.
Each of the above has cultivated his or her own niche in this emerging field of academic thought and pragmatic action. Taken together they may be best considered as mutually reinforcing in synergy. There is a very substantial qualitative difference in the status of spiritual ecology prior to and since their work.
Other leaders in the field include: Leslie Sponsel at the University of Hawai'i, Sarah McFarland Taylor at Northwestern University, Mitchell Thomashow at Antioch University New England and the Schumacher College Programs.
Within the field of science, spiritual ecology is emerging in arenas including Physics, Biology (see: Ursula Goodenough), Consciousness Studies (see: Brian Swimme; California Institute of Integral Studies), Systems Theory (see: David Loy; Nondual Science Institute), and Gaia Hypothesis, which was first articulated by James Lovelock and Lynn Margulis in the 1970s.
Another example is scientist and author Diana Beresford-Kroeger, world recognized expert on how trees chemically affect the environment, who brings together the fields of ethnobotany, horticulture, ecology, and spirituality in relation to the current ecological crisis and stewardship of the natural world. She says, "... the world, the gift of this world is fantastic and phenomenal. The molecular working of the world is extraordinary, the mathematics of the world is extraordinary... sacred and science go together."
Religion and ecology
Within many faiths, environmentalism is becoming an area of study and advocacy. Pope Francis’s May 2015 encyclical, Laudato si', offered a strong confirmation of spiritual ecology and its principles from within the Catholic Church. Additionally, over 150 leaders from various faiths signed a letter to the UN Climate Summit in Paris 2015, “Statement of Faith and Spiritual Leaders on the upcoming United Nations Climate Change Conference, COP21 in Paris in December 2015”, recognizing the earth as “a gift” from God and calling for climate action. These contemporary events are reflections of enduring themes coming to the fore within many religions.
Christian environmentalists emphasize the ecological responsibilities of all Christians as stewards of God's earth, while contemporary Muslim religious ecology is inspired by Qur'anic themes, such as mankind being khalifa, or trustee of God on earth (2:30). There is also a Jewish ecological perspective based upon the Bible and Torah, for example the laws of bal tashchis (neither to destroy wantonly, nor waste resources unnecessarily). Engaged Buddhism applies Buddhist principles and teachings to social and environmental issues. A collection of Buddhist responses to global warming can be seen at Ecological Buddhism.
In addition to Pope Francis, other world traditions currently seem to include a subset of leaders committed to an ecological perspective. The "Green Patriarch," Bartholomew 1, the Ecumenical Patriarch of the Eastern Orthodox Church, has worked since the late nineties to bring together scientists, environmentalists, religious leaders and policy makers to address the ecological crisis, and says protecting the planet is a "sacred task and a common vocation… Global warming is a moral crisis and a moral challenge.” The Islamic Foundation For Ecology And Environmental Sciences (IFEES) were one of the sponsors of the International Islamic Climate Change Symposium held in Istanbul in August 2015, which resulted in "Islamic Declaration on Global Climate Change"—a declaration endorsed by religious leaders, noted Islamic scholars and teachers from 20 countries. In October, 2015, 425 rabbis signed "A Rabbinic Letter on the Climate Crisis", calling for vigorous action to prevent worsening climate disruption and to seek eco-social justice. Hindu scriptures also allude strongly and often to the connection between humans and nature, and these texts form the foundation of the Hindu Declaration on Climate Change, presented at a 2009 meeting of the Parliament of World Religions. Many world faith and religious leaders, such as the Dalai Lama, were present at the 2015 Climate Change Conference, and shared the view that: "Saving the planet is not just a political duty, but also a moral one." The Karmapa, Ogyen Trinley Dorje, has also stated, "The environmental emergency that we face is not just a scientific issue, nor is it just a political issue—it is also a moral issue.”
These religious approaches to ecology also have a growing interfaith expression, for example in The Interfaith Center for Sustainable Development (ICSD) where world religious leaders speak out on climate change and sustainability. And at their gathering in Fall 2015, the Parliament of World Religions created a declaration for Interfaith Action on Climate Change, and "brought together more than 10,000 activists, professors, clergy, and global leaders from 73 countries and 50 faiths to confront climate change"
Earth-based traditions and earth spirituality
Care for and respect to earth as Sacred—as Mother Earth (Mother Nature)—who provides life and nourishment, is a central point to Earth-based spirituality. PaGaian Cosmology is a tradition within Earth-based spirituality that focuses particularly in Spiritual Ecology and celebrating the sacredness of life. Glenys Livingstone describes it in her book as "an ecospirituality grounded in indigenous Western religious celebration of the Earth-Sun annual cycle. By linking to story of the unfolding universe this practice can be deepened. And a sense of the Triple Goddess—central to the cycle and known in ancient cultures—may be developed as a dynamic innate to all being. The ritual scripts and the process of ritual events presented here, may be a journey into self-knowledge through personal, communal and ecological story: the self to be known is one that is integral with place."
Spirituality and ecology
While religiously-oriented environmentalism is grounded in scripture and theology, there is a more recent environmental movement that articulates the need for an ecological approach founded on spiritual awareness rather than religious belief. The individuals articulating this approach may have a religious background, but their ecological vision comes from their own lived spiritual experience. The difference between this spiritually-oriented ecology and a religious approach to ecology can be seen as analogous to how the Inter-spiritual Movement moves beyond interfaith and interreligious dialogue to focus on the actual experience of spiritual principles and practices. Spiritual ecology similarly explores the importance of this experiential spiritual dimension in relation to our present ecological crisis.
The Engaged Buddhist teacher Thich Nhat Hanh speaks of the importance of mindfulness in taking care of our Mother Earth, and how the highest form of prayer is real communion with the Earth. Sandra Ingerman offers shamanic healing as a way of reversing pollution in Medicine for the Earth. Franciscan monk Richard Rohr emphasizes the need to experience the whole world as a divine incarnation. Sufi mystic Llewellyn Vaughan-Lee directs our attention not just to the suffering of the physical world, but also its interior spiritual self, or anima mundi (world soul). Bill Plotkin and others are involved in the work of finding within nature the reconnection with our soul and the world soul. These are just a few of the many different ways practitioners of spiritual ecology within different spiritual traditions and disciplines bring our awareness back to the sacred nature of creation.
The environmental conservation field has been informed, shaped, and led by individuals who have had profound experiences of nature’s sacredness and have fought to protect it. Recognizing the intimacy of human soul and nature, many have pioneered a new way of thinking about and relating to the earth.
Today many aspects of the environmental conservation movement are empowered by spiritual principles and interdisciplinary cooperation.
Robin Wall Kimmerer, Professor of Environmental and Forest Biology at the State University of New York College of Environmental Science and Forestry, has recently founded the Center for Native Peoples and the Environment which bridges scientific based study of ecology and the environment with traditional ecological knowledge, which includes spirituality. As she writes in this piece from Oxford Journal BioScience: "Traditional ecological knowledge is increasingly being sought by academics, agency scientists, and policymakers as a potential source of ideas for emerging models of ecosystem management, conservation biology, and ecological restoration. It has been recognized as complementary and equivalent to scientific knowledge... Traditional ecological knowledge is not unique to Native American culture but exists all over the world, independent of ethnicity. It is born of long intimacy and attentiveness to a homeland and can arise wherever people are materially and spiritually integrated with their landscape."
In recent years, the World Wildlife Fund (World Wide Fund for Nature) has developed Sacred Earth: Faiths for Conservation, a program to collaborate with spiritual leaders and faith communities from all different spiritual traditions around the world, to face environmental issues including deforestation, pollution, unsustainable extraction, melting glaciers and rising sea levels. The Sacred Earth program works with faith-based leaders and communities, who "best articulate ethical and spiritual ideals around the sacred value of Earth and its diversity, and are committed to protecting it."
One of the conservation projects developed from the WWF Sacred Earth program is Khoryug, based in the Eastern Himalayas, which is an association of several Tibetan Buddhist monasteries that works on environmental protection of the Himalayan region through apply the values of compassion and interdependence towards the Earth and all living beings that dwell here. Organized under the auspices of His Holiness, the 17th Karmapa, Ogyen Trinley Dorje, the Khoryug project resulted in the publication of environmental guidelines for Buddhists and "more than 55 monastery-led projects to address forest degradation, water loss, wildlife trade, waste, pollution and climate change."
Krishna Kant Shukla, a Physicist and musician, is noted for his lectures on "Indian Villages as models of sustainable development" and his work in establishing Saha Astitva a model eco village and organic farm in tribal Maharashtra, India.
One trend to note is the recognition that women—by instinct and nature—have a unique commitment and capacity to protect the earth’s resources. We see this illustrated in the lives of Wangari Maathai, founder of Africa’s Green Belt Movement, which was initially made up of women planting trees; Jane Goodall, innovator of local sustainable programs in Africa, many of which are designed to empower girls and women; and Vandana Shiva, the Indian feminist activist working on a variety of issues including seed saving, protecting small farms in India and protesting agri-business.
Other contemporary inter-disciplinary environmentalists include Wendell Berry, a farmer, poet, and academic living in Kentucky, who fights for small farms and criticizes agri-business; and Satish Kumar, a former Jain monk and founder of Schumacher College, a center for ecological studies.
Although the May 2015 Encyclical from Pope Francis brought the importance of the subject spiritual ecology to the fore of mainstream contemporary culture, it is a point of view that is not widely accepted or included in the work of most environmentalists and ecologists. Academic research on the subject has also generated some criticism.
There has also been criticism of some aspects of ecological spirituality by Ken Wilber, who suggests that “spiritually oriented deep ecologists” fail to acknowledge the transcendent aspect of the divine, or hierarchical cosmologies, and thus exclude an important aspect of spirituality, as well as presenting what Wilber calls a one-dimensional “flat land” ontology in which the sacred in nature is wholly immanent. But Wilber's views are also criticized as not including an in-depth understanding of indigenous spirituality.
