Ecopsychology studies the relationship between human beings and the natural world through ecological and psychological principles. The field seeks to develop and understand ways of expanding the emotional connection between individuals and the natural world, thereby assisting individuals with developing sustainable lifestyles and remedying alienation from nature. Theodore Roszak is credited with coining the term in his 1992 book, The Voice of the Earth. He later expanded the idea in the 1995 anthology Ecopsychology with co-editors Mary Gomes and Allen Kanner. Two other books were especially formative for the field, Paul Shepard's 1982 volume, "Nature and Madness", which explored the effect that our ever-diminishing engagement with wild nature had upon human psychological development, and philosopher David Abram's The Spell of the Sensuous: Perception and Language in a More-than-Human World, published in 1996. The latter was the first widely-read book to bring phenomenology to bear on ecological and ecopsychological issues, examining in detail the earthly dimensions of sensory experience, and disclosing the historical effect of formal writing systems upon the human experience of nature's agency, voice, and interiority.
A central premise of ecopsychology is that while today the human mind is affected and shaped by the modern social world, its deep structure is inevitably adapted to, and informed by, the more-than-human natural environment in which it evolved. According to the biophilia hypothesis of biologist E.O. Wilson, human beings have an innate instinct to connect emotionally with nature, particularly the aspects of nature that recall what evolutionary psychologists have termed the environment of evolutionary adaptiveness, the natural conditions that the human species evolved to inhabit.
The field of ecopsychology extends beyond the conventional purview of psychology, which had traditionally considered the psyche to be a matter of relevance to humans alone. Ecopsychology examines why people continue environmentally damaging behaviour, and to develop methods of positive motivation for adopting sustainable practices. Evidence suggests that many environmentally damaging behaviours are addictive at some level, and thus are more effectively addressed through positive emotional fulfillment rather than by inflicting shame. Other names used to refer to ecopsychology include depth ecology, Gaia psychology, psychoecology, ecotherapy, environmental psychology, green psychology, transpersonal ecology, global therapy, green therapy, Earth-centered therapy, reearthing, nature-based psychotherapy, shamanic counselling, ecosophy  and sylvan therapy.
Certain researchers propose that an individual's connection to nature can improve their interpersonal relationships and emotional wellbeing. An integral part of this practice is to remove psychotherapy, and the individual, from the interior of office buildings and homes and place them outdoors. According to the precepts of ecopsychology, a walk in the woods or a city park is refreshing because it is what humans evolved to do. Psychologists such as Roger Ulrich, Rachel and Stephen Kaplan, Frances Kuo and others have studied the beneficial effects of inhabiting natural settings and of looking at pictures of landscapes on the human psyche. Richard Louv's Last Child in the Woods: Saving our Children from Nature-Deficit Disorder discusses in detail how the exposure of children to nature can assist in treating mental disorders, including attention deficit disorder.
Another premise of ecopsychology is that steps taken to accept and notice nature can sharpen the senses and help people cultivate new skills. For example, the ability to track and navigate through a wilderness is improved if nature is noticed and accepted rather than feared. Similarly, ecopsychology proposes that sailors who appreciate the sea gain a keen sense for breeze directions.
Reasons to embrace nature
Ecopsychology explores how to develop emotional bonds with nature. It considers this to be worthwhile because when nature is explored and viewed without judgement, it gives the sensations of harmony, balance, timelessness and stability. Ecopsychology largely rejects reductionist views of nature that focus upon rudimentary building blocks such as genes, and that describe nature as selfish and a struggle to survive. Ecopsychology considers that there has been insufficient scientific description and exploration of nature, in terms of wildness, parsimony, spirituality and emotional ties. For example, parsimony is the best way to produce an evolutionary tree of the species (cladistics), suggesting that parsimonious adaptations are selected. Yet today, the brain is often seen as complicated and governed by inherited mind modules, rather than being a simple organ that looks for parsimony within the influences of its surroundings, resulting in the compaction in minds of a great diversity of concepts.
Cultures that embrace nature
In its exploration of how to bond with nature, ecopsychology is interested in the examples provided by a wide variety of ancient and modern cultures that have histories of embracing nature. Examples include aboriginal, pagan, Buddhist, and Hindu cultures, as well as shamanism and the more recent hesychast tradition. Of interest is how identity becomes entwined with nature, so that loss of those sacred places is far more devastating to indigenous people than often understood. Native American stories, in particular, illustrate a socially recognized sense of community between humans and the natural landscape. The Māori philosophy, and practice of kaitiakitanga, or eco-guardianship, and preservation emphasizes a deep connect between humans, and their environment. Eastern Orthodox monks led a contemplative life deeply intertwined with nature. Other lessons include how to live sustainably within an environment and the self-sacrifices made to tolerate natural limits, such as population control or a nomadic existence that allows the environment to regenerate. Moreover, certain indigenous cultures have developed methods of psychotherapy involving the presence of trees, rivers, and astronomical bodies.
Pain and delusions without nature
Ecopsychologists have begun detecting unspoken grief within individuals, an escalation of pain and despair, felt in response to widespread environmental destruction. The field of ecopsychology intends to illustrate how environmental disconnection functions as an aspect of existing pathologies, without creating a new category. The contention is that if a culture is disconnected from nature, then various aspects of an individual's life will be negatively impacted. It also believes that that without the influence of nature, humans are prone to a variety of delusions, and that to some degree life in the wild forms the basis for human sanity and optimal psychological development. The topic is explored in detail Paul Shepard's book Nature and Madness. It is also proposed that separation from outdoor contact causes a loss of sensory and information-processing ability that was developed over the course of human evolution, which was spent in direct reciprocity with the environment.
