Naturism

From Wikipedia, the free encyclopedia

Naturism, or nudism, is a cultural and political movement practising, advocating, and defending personal and social nudity, most but not all of which takes place on private property. The term may also refer to a lifestyle based on personal, family, or social nudism. Naturism may take a number of forms. It may be practiced individually, within a family, socially, or in public. Additionally, there is also militant naturism, including campaigning, and extreme naturism is sometimes considered a separate category.

Definition and lexicology

The XIV Congress of the International Naturist Federation (Agde, France, 1974) defined naturism as:
a way of life in harmony with nature characterised by the practice of communal nudity with the intention of encouraging self-respect, respect for others and for the environment.
Several other terms ("social nudity", "public nudity", "skinny dipping", "sunning", and "clothes-free") have been proposed as alternative terms for naturism, but none has found the same widespread public acceptance as the older terms "naturism" and (in much of the United States) "nudism".

People interested in social nudity can attend clothes-free beaches and other types of ad-hoc nudist events. At these venues, participants generally need not belong to a nudist club.

Many contemporary naturists and naturist organisations feel that the practice of social nudity should be asexual. For various social, cultural, and historical reasons the lay public, the media, and many contemporary naturists and their organisations often oversimplify the relationship between naturism and sexuality. Current research has begun to explore this complex relationship.

The International Naturist Federation explains:
"Each country has its own kind of naturism, and even each club has its own special character, for we too, human beings, have each our own character which is reflected in our surroundings."
The usage and definition of these terms varies geographically and historically. Though in the United States, naturism and nudism have the same meaning, in Britain there is a clear distinction.

Nudism is the act of being naked, while naturism is a lifestyle which at various times embraced nature, environment, respect for others, self-respect, crafts, healthy eating, vegetarianism, teetotalism, non-smoking, yoga, physical exercise and pacifism as well as nudity.

In naturist parlance, textile or textilist is a non-naturist person, non-naturist behaviour or non-naturist facilities. e.g. the textile beach starts at the flag, they are a mixed couple – he is naturist, she is textile. Textile is the predominant term used in the UK ('textilist' is unknown in British naturist magazines including H&E naturist), although some naturists avoid it due to perceived negative or derogatory connotations. Textilist is said to be used interchangeably, but no dictionary definition to this effect exists, nor are there any equivalent examples of use in mainstream literature such as those for textile. Clothing optional and nude optional (US specific) describe a policy or a venue that allows or encourages nudity but tolerates the wearing of clothes. The opposite is clothing compulsory; that is, prohibiting nudity. Adjectival phrases clothes free and clothing free prescribe where naturism is permitted in an otherwise textile environment, or define the preferred state of a naturist.

The social nudity movement includes a large range of variants including "naturism", "nudism", "Freikörperkultur (FKK)", the "free beach movement" as well as generalized "public lands/public nudity" advocacy. There is a large amount of shared history and common themes, issues and philosophy, but differences between these separate movements remain contentious.

Personal and family nudity

Many people are often nude in the privacy of their home or garden, either alone or with members of the family; naturists normally refer to them as at-home-nudists or closet-nudists. This may be occasional nudity or as a naturist lifestyle. There are differences of opinion as to whether, and if so to what extent, parents should appear naked in front of their children, and whether children should be nude within the home in the view of their family as well as visitors. This has attracted a great deal of academic study.

A United States study by Alfred Kinsey (1948–1953) found that 75% of the participants stated that there was never nudity in the home when they were growing up, 5% of the participants said that there was "seldom" nudity in the home, 3% said "often", and 17% said that it was "usual". The study found that there was no significant difference between what was reported by men and by women with respect to frequency of nudity in the home.

Gordon and Schroeder in 1995 reported that parental nudity varies considerably from family to family. They say that "there is nothing inherently wrong with bathing with children or otherwise appearing naked in front of them", noting that doing so may provide an opportunity for parents to provide important information. They note that by ages 5 to 6 children begin to develop a sense of modesty, and recommend to parents who wish to be sensitive to their children's wishes that they limit such activities from that age onwards.

Barbara Bonner in 1999 cautioned against nudity in the home if children exhibit sexual play of a type that is considered problematic.

In a 1995 review of the literature, Paul Okami concluded that there was no reliable evidence linking exposure to parental nudity to any negative effect. Three years later, his team finished an 18-year longitudinal study that showed that, if anything, such exposure was associated with slight beneficial effects, particularly for boys.

Smith and Sparks in their study on the effects of social nudity on children conclude that "the viewing of the unclothed body, far from being destructive to the psyche, seems to be either benign and totally harmless or to actually provide positive benefits to the individuals involved.

Social nudism

The rhetoric of the nudism and anti-nudism movements emphasizes freedom from many of the normal constraints which regulate human interaction in nudist settings, although for different reasons. Using data from French and German beaches, this hypothesis was tested using five different indicators. Little significant variation between nudists and non-nudists within French and German settings is found in their patterns of interactional spacing, while more significant main effects for differences of cultures are found regardless of nudity status. As a subculture, nudists would appear to differ from nonnudists only in their propensity to like to sunbathe in the nude. Their nude status would appear to have none of the de-inhibiting effects often attributed to nudism. By contrast, clear cultural differences between German and French cultures are shown consistent with Hall's high-low context distinction and the Francoeur's hot-cool sexuality continuum.

Naturist facilities

At naturist organised events or venues clothing is usually optional, except by swimming pools or sunbathing lawns where complete nudity is expected, weather permitting. This rule is sometimes a source of controversy among some naturists. Staff at a naturist facility are usually required to be clothed due to health and safety regulations.

Facilities for naturists are classified in various ways. A landed or members' naturist club is one that owns its own facilities, while non-landed (or travel) clubs meet at various locations, such as private residences, swimming pools, hot springs, landed clubs and resorts, and rented facilities. Landed clubs can be run by members on democratic lines or by one or more owners who make the rules. In either case, they can determine membership criteria and the obligations of members. This usually involves sharing work necessary to maintain or develop the site.

Some clubs have stricter entrance requirements than some traditional 'country clubs', including the requirement to supply references, a sponsoring member, a trial membership, committee approval or, criminal background checks. UK clubs are now required to have child-protection policies in place, and designated child-protection officers. Many clubs promote frequent social activities.

The international naturist organizations were mainly composed of representatives of landed clubs. Nudist colony is no longer a favored term, but it is used by naturists as a term of derision for landed clubs that have rigid non-inclusive membership criteria, and in meta-data on naturist websites.

A holiday centre is a facility that specializes in providing apartments, chalets and camping pitches for visiting holidaymakers. The center is run commercially, and visitors are not members and have no say in the management. Most holiday centers expect visitors to hold an INF card, that is, be a member of their national organization, but some have relaxed this restriction, relying on the carrying of a trade card. Holiday centers can be quite small, just a couple of hectares or large occupying over 300 hectares. In a large holiday centre there will be swimming pools, sports pitches, an entertainment program, kids' clubs, restaurants and supermarkets. Some holiday centres allow regular visitors to purchase their own chalets, and generations of the same families will visit each year. Holiday centres are more tolerant of clothing than members-only clubs; total nudity is usually compulsory in the swimming pools and may be expected on the beaches, while on the football pitches, or in the restaurants in the evening, it is rare.

A naturist resort is, to a European, an essentially urban development where naturism is the norm. Cap d'Agde in France, naturist village Charco del Palo on Lanzarote, Canary Islands, Vera Playa in Spain and Vritomartis in Greece are examples. Some residents use these resorts as a year-round home.

In US usage, a naturist resort can mean a holiday centre.

Freikörperkultur (FKK) literally translated as 'free body culture' is the name for the general movement in Germany. The abbreviation is widely recognised all over Europe and often found on informal signs indicating the direction to a remote naturist beach.

Nude beaches

Clothing is optional at nude beaches (or "free beaches"). A feature of bathing on a nude beach is the anonymity it offers, with membership of a club not being required, nor detailed application processes, nor pre-booking of visits.

In some European countries, such as Denmark, all beaches are clothing optional, while in others like Germany and experimentally in France, there are naturist sunbathing areas in public parks, e.g., in Munich and Berlin. Beaches in some holiday destinations, such as Crete, are also clothing-optional, except some central urban beaches. There are two centrally located clothes-optional beaches in Barcelona.

Naturism and sports

Naturism encourages a healthy life style, and many naturist clubs at times organize and encourage members to take part in local and international sport events and competitions. The German Association for Free Body Culture (DFK) promotes recreational sports and is a member of the German Olympic Sport Federation (DOSB).

Festival naturism

From Woodstock to Edinburgh, and Nambassa in the southern hemisphere communal nudity is commonly recorded at music and counterculture festivals.

The series of 1970s Nambassa hippie festivals held in New Zealand is a further example of non-sexualized naturism. Of the 75,000 patrons who attended the 1979 Nambassa 3 day counterculture Festival an estimated 35% of festival attendees spontaneously chose to remove their clothing, preferring complete or partial nudity.'

Roskilde festival in Denmark hosts a naked run, that has become one of the most popular events there.

Perhaps nowadays the biggest and most famous festival where participants spontaneously decide to go naked or take part in nude events is Burning Man: it's got its own naked bike ride aka 'Naked Pub Crawl', and a few camps organize activities in the nude, including the famous oil wrestling by camp Gymnasium.

Florida Young Naturists has organized seasonal "Bashes" hosted by several Florida nudist/naturist clubs and resorts since 2008.

Organized by the Federación Nudista de México (Mexican Nudist Federation) since 2016 when Zipolite beach nudity was legalized, FESTIVAL NUDISTA ZIPOLITE occurs annually on the first weekend of February.

Nudist festivals are also held to celebrate particular days of the year, and in many such events nude bodypainting is also common, such as Neptune Day Festival held in Koktebel, Crimea to depict mythological events; the Solstice Cyclists nudist events celebrating the summer solstice held in Fremont, Seattle, United States; the Naked Pumpkin Run held in US to celebrate Halloween; and the World Naked Gardening Day held to celebrate gardening.

Summer naturism

The prevalence of naturism tends to increase during the summer months especially when the temperature is higher with some regions experiencing first-time naturists and people who have transitioned to becoming a naturist. Some studies have observed that among some of these naturists, they are clothed during other seasons, thus making them seasonal naturists. This quiddity has caught the public perception and comprehension of public nudity, and thus it is frequently equated with summer destinations such as beaches.

History

Nudity in social contexts has been practised in various forms by many cultures at all time periods. In Western society nowadays, social nudity is most frequently encountered in the contexts of bathing, swimming and in saunas, whether in single-sex groups, within the family or with mixed-sex friends, but throughout history and in many tropical cultures until now, nudity is a norm at many sports events and competitions.

It is difficult to nominate exactly when naturism started as a movement. The word 'naturism' was used for the first time in 1778 by a French-speaking Belgian, Jean Baptiste Luc Planchon (1734–1781), and was advocated as a means of improving the hygiène de vie or healthy living.

The earliest known naturist club in the "western" sense of the word was established in British India in 1891. The 'Fellowship of the Naked Trust' was founded by Charles Edward Gordon Crawford, a widower, who was a District and Sessions Judge for the Bombay Civil Service. The commune was based in Matheran and had just three members at the beginning; Crawford and two sons of an Anglican missionary, Andrew and Kellogg Calderwood. The commune fell apart when Crawford was transferred to Ratnagiri; he died soon after in 1894.

Max Koch's Freilicht, 1897

In 1902, a series of philosophical papers was published in Germany by Dr. Heinrich Pudor, under the pseudonym Heinrich Scham, who coined the term Nacktkultur. In 1906 he went on to write a three volume treatise with his new term as its title, which discussed the benefits of nudity in co-education and advocated participating in sports while being free of cumbersome clothing. Richard Ungewitter (Nacktheit, 1906, Nackt, 1908, etc.) proposed that combining physical fitness, sunlight, and fresh air bathing, and then adding the nudist philosophy, contributed to mental and psychological fitness, good health, and an improved moral-life view. Major promoters of these ideas included Adolf Koch and Hans Suren. Germany published the first journal of nudism between 1902 and 1932.

The wide publication of those papers and others, contributed to an explosive worldwide growth of nudism, in which nudists participated in various social, recreational, and physical fitness activities in the nude. The first organized club for nudists on a large scale, Freilichtpark (Free-Light Park), was opened near Hamburg in 1903 by Paul Zimmerman. In 1919, German doctor Kurt Huldschinsky discovered that exposure to sunlight helped to cure rickets in many children, causing sunlight to be associated with improved health.

In France in the early 20th century, the brothers Gaston and André Durville, both of them physicians, studied the effects of psychology, nutrition, and environment on health and healing. They became convinced of the importance of natural foods and the natural environment on human well-being and health. They named this concept French: naturisme. The profound effect of clean air and sunlight on human bodies became evident to them and so nudity became a part of their naturism.

Naturism became a more widespread phenomenon in the 1920s, in Germany, the United Kingdom, France and other European countries and spread to the United States where it became established in the 1930s.

By 1951, the national federations united to form the International Naturist Federation or INF. Some naturists preferred not to join clubs, and after 1945, pressure was put to designate beaches for naturist use. From the middle of the 20th century, with changing leisure patterns, commercial organisations began opening holiday resorts to attract naturists who expected the same – or better – standards of comfort and amenity offered to non-naturists. More recently, naturist holiday options have expanded to include cruises.

Philosophy

Finnish Sauna (1802)

Naturism had many different philosophical sources and means many things to different people. There is no one definition. In 1974, the INF defined naturism as:
a way of life in harmony with nature characterised by the practice of social nudity with the intention of encouraging self-respect, respect for others and for the environment.
At one end of the spectrum are the nudists who just enjoy a nude life style, and at the other are the naturists, who have deeply held beliefs and see communal nudity as just one of many important principles.

The naturist philosophy has several sources, many of which can be traced back to early 20th century health and fitness philosophies in Germany and England, although the concepts of returning to nature and creating equality have much deeper roots.


Gymnosophy and religious nakedness

In the 4th century BC, Alexander the Great encountered, in India, wandering groups of naked holy men whom he dubbed the naked philosophers. (Gr gymnos: naked; sophist: knowledge). The philosopher Onesicritus investigated their beliefs and lifestyle. Pyrrho the Sceptic was impressed and incorporated nudity into his philosophy. The Gymnosophists were Hindus, but Jain and Ajivika monks practiced nudity as a statement that they had given up all worldly goods. Nudity was not a new concept to the Greeks as the Olympic Games (founded in 776 BC) were exclusively male and nude events.

Historically, the Adamites, a Gnostic sect, practiced religious nudism. Another religious sect, the Doukhobors, migrated from Russia to western Canada. They practice or practiced occasional nudity, such as while working in the farm fields. Members of one of the three subdivisions of Canadian Doukhobors, the small radical Sons of Freedom group, went so far in the 1900s as to publicly strip in mass public demonstrations to protest against government policies which were meant to assimilate them. Today, Christian naturism contains various members associated with most denominations. Although beliefs vary, a common theme is that much of Christianity has misinterpreted the events regarding the Garden of Eden, and God was displeased with Adam and Eve for covering their bodies with fig leaves.

The first English naturists adopted the name Gymnosophy as a thinly disguised euphemism for their pastime. The English Gymnosophical Society was formed in 1922 and became the New Gymnosophy Society in 1926; they purchased land at 'Bricketts Wood' to become Britain's first nudist colony. One of the first members was Gerald Gardner, who in 1945 established the 'Five Acres Club' nearby, ostensibly as a nudist club, but as a front for Wiccans, as witchcraft was illegal in England until 1951.

The Digambar, one of the two main divisions of the Jain religion of India, remain skyclad, or naked, though generally it is practiced by males. Digambar means 'clothed with the sky'. Wiccans have adopted this wording and some practice their rituals skyclad.

Naturist writers

  • Elton Raymond Shaw was a Methodist churchman and publisher who wrote on the Body Taboo.
  • Heinrich Pudor wrote on methods to improve social hygiene in his book Nackende Menschen und Jauchzen der Zukunft (Naked people and the future of Mankind) and then Nacktkultur (Nude Culture). It prescribes an austere lifestyle and nudity.
  • Paul Zimmermann opened the Freilicht Park in Lübeck which was open to those who subscribed to Nacktkultur principles.
  • Richard Ungewitter wrote Die Nacktheit (Nakedness) which sold 90,000 copies, prescribed a similar Utopian lifestyle, where everyone would be nude, eat only vegetables and abstain from alcohol and tobacco. In his Utopia, everyone was to be Germanic with blue eyes and blonde hair.
  • Adolf Koch, a left-wing primary-school teacher, sought to use social nudity to free the people from 'authority fixated conditioning which held proletarians in deference of their masters: parental authority, paternalism of the church, the mass media and organs of law and order. He used Organic-Rhythmic exercises in Berlin schools in the 1920s. In 1932 there were about 100,000 Germans involved with Naturism, of which 70,000 were in Koch's Körperschülen schools.
  • Hans Surén taught nude gymnastics to soldiers for five years, and on being forced to leave the army, he wrote in 1924, Mensch und die Sonne (Men and the Sun) which ran to 61 reprints. Later, in 1936, Surén proposed physical exercise and naturism as a means of creating a pure German race and of beauty. In the early 1940s he was out of favour and arrested. By 1945, he had turned full circle and was writing religious texts. Though never a member of any FKK club he was awarded honorary membership of the DFK in 1952.
  • Werner Zimmermann was Swiss. He promoted Progressive education, encouraging naked Physical education to eliminate body guilt and to encourage openness that would lift the repression of the human spirit, which he saw as the cause of sexual deviation. The basic position was that the human body, in and of itself, was neither sinful nor obscene. This was adopted into the emerging philosophy that created the modern Western nudist movement.

Naturist ideals

Family in Praia do Abricó, Brazil

Individuals have formed naturist groups for a variety of specific purposes. It is generally agreed by naturist organisations that eroticism and blatant sexuality have no place in naturism and are, in fact, antithetical to its ideals. Reasons that have at times been given:
  • Ecological or environmental — rapport with the natural world.
  • Health — bathing in the sun, fresh air and water (balneotherapy, thalassotherapy, heliotherapy). Sun is a form of medicine.
  • Diet — Naturism has at times been associated with claims made for moderation with alcohol, meat, tobacco, drugs; leading to a teetotal, vegetarian or vegan lifestyle.
  • Psychologically — rapport with other humans including equality and respect. Being nude in groups makes all feel more accepted – physically, intellectually and emotionally.
  • Spirituality — nudity, well being and direct contact to nature helps feel closer to the universe.[citation needed]
  • Pedagogy — children should be respected as equals instead of being patronised
  • Equality — clothes build social barriers. Social nudity leads to acceptance in spite of differences in age, body shape, fitness, and health.
  • Liberty — no one has the right to tell others or their children that they must wear clothes.

Naturism and the romantics

Walt Whitman American writer, A Sun-bathed Nakedness:
Never before did I get so close to Nature; never before did she come so close to me... Nature was naked, and I was also... Sweet, sane, still Nakedness in Nature! - ah if poor, sick, prurient humanity in cities might really know you once more! Is not nakedness indecent? No, not inherently. It is your thought, your sophistication, your fear, your respectability, that is indecent. There come moods when these clothes of ours are not only too irksome to wear, but are themselves indecent.
Henry David Thoreau, In wildness is the preservation of the world., Walking:
We cannot adequately appreciate this aspect of nature if we approach it with any taint of human pretense. It will elude us if we allow artifacts like clothing to intervene between ourselves and this Other. To apprehend it, we cannot be naked enough.
Naturism was part of a literary movement in the late 1800s (see the writings of André Gide) which also influenced the art movements of the time specifically Henri Matisse and other Fauve painters. This movement was based on the French concept of joie de vivre, the idea of reveling freely in physical sensations and direct experiences and a spontaneous approach to life.

Naturism for health

Sunlight has been shown to be beneficial in some skin conditions and enables the body to make vitamin D, but with the increased awareness of skin cancer, wearing of sunscreen is now part of the culture. Sun exposure prompts the body to produce nitric oxide that helps support the cardiovascular system and the feelgood brain-chemical serotonin.

There are also documented psychological benefits of naturist activities including greater life satisfaction, more positive body image, and higher self-esteem.

World Naked Bike Ride

WNBR passing Holborn underground station 11 June 2016

The World Naked Bike Ride (WNBR) is an international clothing-optional bike ride and exercise in public nudity, that has developed outside the organised naturism movement. Participants plan, meet and ride together en masse on human-powered transport (the vast majority on bicycles, but some on skateboards and inline skates), to "deliver a vision of a cleaner, safer, body-positive world." The WNBR shares some aspects of the philosophy of naturism in that it promotes a return to healthy exercise in unpolluted air at the same time promoting positive body image.

Demographics

  • In 1999, the Federation of Canadian Naturists commissioned a national survey on Canadian attitudes towards nudity[60] which found that 8.9% of Canadian have visited or would visit a naturist facility. A further 11.6% have gone or would go skinny dipping in mixed company; that 39% go naked in their own homes; that naturists tend to have above average incomes; that urban dwellers are more likely to be naturist than country dwellers; and that the under 25s are the most likely to be naturists.
  • In 1983, the Naturist Society in the United States sponsored a Gallup poll, which was repeated in 2000, which found the following:

In Europe

Finland

In Finnish culture, nudism is considered to be a relatively normal way to live. It is not uncommon to see entire families spending time together naked. Families may be naked while bathing in a sauna, swimming in a pool, or playing on a beach, and it's not unusual to see children playing naked in a kindergarten or family yard for example. Nudity as a whole is considered less taboo than many other countries.

France

In 1903 la Revue des deux mondes published a report on German naturism and S. Gay created a naturist community at Bois-Fourgon. In 1907, supported by his superiors, Abbé Legrée encouraged the students at his Catholic college to bathe nude on the rocky beaches near Marseille.

Marcel Kienné de Mongeot is credited with starting naturism in France in 1920. His family had suffered from tuberculosis, and he saw naturism as a cure and a continuation of the traditions of the ancient Greeks. In 1926, he started the magazine Vivre intégralement (later called Vivre) and the first French naturist club, Sparta Club at Garambouville, near Evreux. The court action that he initiated, established that nudism was legal on private property that was fenced and screened.

Drs. André and Gaston Durville bought a 70 hectare site on the Île du Levant where they established the village of Héliopolis. The village was open to the public. In 1925 Dr François Fougerat de David de Lastours wrote a thesis on heliotherapy. and in that year opened the Club gymnique de France. In 1936, the naturist movement was officially recognised.

Albert and Christine Lecocq were active members of many of these clubs, but after disagreements left and In 1944 Albert and Christine Lecocq founded the Club du Soleil with members in 84 cities. In 1948 they founded the FFN, in 1949 they started the magazine, Vie au Soleil and in 1950 opened the CHM Montalivet, the world's first naturist holiday centre where the INF was formed.

The naturist village Leucate and Cap d'Agde offers a different form of social nudity. Euronat is the largest holiday centre (335ha) situated 10 km north of Montalivet. Naturism employs more than 3000 people, and is estimated to be worth 250 million Euro to the French economy. France is represented on the INF by the FFN.

Germany

German naturism was part of the Lebensreform movement and the Wandervogel youth movement of 1896, from Steglitz, Berlin which promoted ideas of fitness and vigour. At the same time doctors of the Natural Healing Movement were using heliotherapy, treating diseases such as TB, rheumatism and scrofula with exposure to sunlight.

Nacktkultur, a term coined in 1903 by Heinrich Pudor, flourished. Nacktkultur connected nudity, vegetarianism and social reform. It was practised in a network of 200 members clubs. The movement gained prominence in the 1920s as offering a health giving life-style with Utopian ideals. Germany published the first naturist journal between 1902 and 1932. It became politicised by radical socialists who believed it would lead to classlessness and a breaking down of society. It became associated with pacificism.

In 1926, Adolf Koch established a school of naturism in Berlin; encouraging a mixing of the sexes, open air exercises, and a programme of "sexual hygiene". In 1929, the Berlin school hosted the first International Congress on Nudity.

During the National Socialist Gleichschaltung era, all naturist clubs had to register with the Reichsbund für Leibesübungen, which meant excluding Jews and Communists. Also, they had to keep all activities hidden in the countryside where there was little chance of being seen by others. The status as a West German sports federation member gave the clubs rights and privileges (e.g. tax exemptions) so the naturist clubs remained in the federation after the war had ended.

After the war, East Germans were free to practice naturism, chiefly at beaches rather than clubs (private organizations being regarded as potentially subversive). Naturism became a large element in DDR politics. The Proletarische Freikörperkulturbewegung subsection of the Workers Sports Organisation had 60,000 members. Today, following reunification there are many clubs, parks and beaches open to naturists, though nudity has become less common in the former eastern zone. Germans are typically the most commonly seen foreigners at nude beaches in France and around Europe.

Greece

Public nudity is prohibited in Greece and there are no official nude beaches. There are, however, numerous unofficial nude beaches especially on the islands frequented by tourists, like Crete, Mykonos or Karpathos but also on smaller islands like Skopelos or Skiathos where nudity is tolerated, usually at the more remote ends or secluded areas of beaches.

Italy

Public nudity is prohibited in Italy and can be punished with high fines, but in the recent decade, a few regions have created naturism laws to help the tourism industry. There are only a few permitted nude beaches in those regions, where nudity is allowed without risking legal consequences. On all other public beaches in Italy as well as normally tolerated nude beaches, police can potentially impose substantial fines.

Poland

First reported naturist society was established in 1897 in Grudziądz. In pre-war and post-war Poland, naturism was practised in closed and secluded areas. Reported places for naturism were Zaleszczyki (in today's Ukraine) and Otwock. Under the communism regime, Poland's naturism became unofficial and was practiced mostly by the artistic boheme near Krynica Morska, Misdroy and Dębki.

In the early 1980s naturism became popular mostly due to increased interest in media. As the pop song "Chałupy Welcome To" (about the naturist beach in Chałupy, featuring beach nudity in the clip) became the 1985 summer hit in Poland, the nude seaside locations like Chałupy or Rowy became known to an average Polish sunbather. Polish Naturist Society was formed and after the number of lawsuits, naturism became tolerated in selected "unofficial" beaches and distant spots.

In today's Poland naturism is practiced in number of the seaside and inland beaches. Most Polish beaches are actually clothes-optional rather than naturist. Among the most popular locations are Misdroy-Lubiewo, Grzybowo, Rowy, Dębki, Gdańsk-Stogi and Piaski. The most popular inland locations include Warsaw (Wał Miedzeszyński), Kazimierz Dolny and Kryspinów near Kraków. In the winter season, naturism is practiced by organized groups in Warsaw and Tri-City. Public naturist events are held bi-monthly in Poznań-Koziegłowy and Łódź waterpark.

Portugal

Naturism in Portugal had its first historical record around 1920, linked to the Portuguese Naturist Society, of which the anarcho-syndicalist José Peralta was a prominent member. Nudity was already being practiced on Costa da Caparica beaches. With the beginning of the New State authoritarian regime in the 1930s, the naturist movement was limited to vegetarian and alternative medicines, since nudity was banned and associated to the crime of "indecency". Only after the end of the New State regime in 1974 (April, 25th) the activities linked to the practice of nudity were resumed.

The Federação Portuguesa de Naturismo (Portuguese Naturist Federation) or FPN was founded on the March 1st, 1977, at a meeting in Lisbon.

At the present, there are seven official naturist beaches in Portugal. Besides these, there are several dozens of beaches were the practice of naturism is common. There are also several naturist campings and resorts.

Slovenia

Beginnings of naturism in Slovenia started in the year 1852, when a 29 year old Swiss physician Arnold Rikli visited Bled for the first time. In the following years he started to promote healthy way of living, because he considered water, air and light to be the source for his healing therapy. He continued to build spa centers which included light therapy and hydrotherapy treatment. His first visitors were most likely pilgrims from Slovenia and Friuli-Venezia Giulia region who visited the church on Bled island. When the word has spread across Europe, other visitors started visiting Bled known for Rikli's healing therapy. A method used in the healing therapy process included sunbathing and visitors were often seen walking nude in public. Rikli continued to promote his healing tourism for the next 52 years, when he lived in Bled.

Spain

Public nudity in Spain is not illegal since there is no law banning its practice. Spanish legislation foresees felony for exhibitionism but restricts its scope to obscene exposure in front of children or mentally impaired individuals, i.e. with sexual connotation. However, people do not normally use this right to be naked to do it anywhere, and most usually perform this activity in places where nudism is a tradition.

There are however some municipalities (like San Pedro del Pinatar) where public nudity has been regulated (banned) by means of by-laws. Other municipalities (like Barcelona, Salou, Platja de Palma and Sant Antoni de Portmany) have also used these provisions to regulate the practice of semi-nudism, forcing people to cover their torso on the streets. Some naturist associations have appealed these by-laws on the grounds that a fundamental right (freedom of expression, as they understand that nudism is a way of self-expression) cannot be regulated with this mechanism. Some judicial instances have ruled in favour of nudist associations.

Nudism in Spain is normally practised by the seaside, on beaches or small coves with a tradition on naturism. In Vera (Andalusia), there is a wide residential area formed by nudist urbanisations that constitute some kind of nudist town. Nudist organisations may organise some activities elsewhere in inner territory (like hiking on the mountains close to Madrid), but these kind of activities are negligible. Madrid municipality enables nudist use of some of their public swimming pools one day during summer.

Textile use of traditionally nudist public spaces (like beaches or streets nearby) is allowed, mainly due to lack of regulation. Mixed groups of nudist and textile individuals are frequent in these kind of spaces. In order to chase voyeuristic persons away, nudist people will normally clap their hands.
Legal aspects regarding topless are analogue to those regarding nudism, but social tolerance towards topless is higher. This let people not cover their breasts in public swimming pools and on any beach in Spain.

United Kingdom

In the United Kingdom, the first official nudist club was established in Wickford, Essex in 1924. According to Michael Farrar, writing for British Naturism the club adopted the name "Moonella Group" from the name of the owner of the ground, Moonella, and called its site The Camp. Moonella, who was still living in 1965 but whose identity remains to be discovered, had inherited a house with land in 1923 and made it available to certain members of the New Gymnosophy Society. This society had been founded a few years before by H.C. Booth, M.H. Sorensen and Rex Wellbye under the name of the English Gymnosophical Society. It met for discussions at the Minerva Cafe at 144 High Holborn in London, the headquarters of the Women's Freedom League. Those who were permitted to join the Moonella Group were carefully selected, and the club was run by an "aristocracy" of the original members, all of whom had "club names" to preserve their anonymity. The club closed in 1926 because of building on adjacent land.

By 1943 there were a number of these so-called "sun clubs" and together they formed the British Sun Bathers Association or BSBA. In 1954 a group of clubs unhappy with the way the BSBA was being run split off to form the Federation of British Sun Clubs or FBSC. In 1961, the BSBA Annual Conference agreed that the term nudist was inappropriate and should be discarded in favour of naturist. The two organisations rivalled each other before eventually coming together again in 1964 as the Central Council for British Naturism or CCBN. This organisation structure has remained much the same but it is now called British Naturism which is often abbreviated to BN. BN is currently a company limited by guarantee.

The first official nude beach was opened at Fairlight Glen in Covehurst Bay near Hastings in 1978 (not to be confused with Fairlight Cove, which is 2 km to the east) followed later by the beaches at Brighton and Fraisthorpe. Bridlington opened in April 1980.

In North America

Canada

In Canada, individuals around the country became interested in nudism, skinny-dipping, and physical culture in the early part of the 20th century. After 1940 they had their own Canadian magazine, Sunbathing & Health, which occasionally carried local news. Canadians had scattered groups in several cities during the 1930s and 1940s, and some of these groups attracted enough interest to form clubs on private land. The most significant clubs were the Van Tan Club, formed in 1939, and continues today in North Vancouver, BC., and, in Ontario, the Sun Air Club.

Canadians who served in the military during the Second World War met like-minded souls from across the country, and often visited clubs while in Europe. They were a ready pool of recruits for post-war organizers. A few years later, the wave of post-war immigration brought many Europeans with their own extensive experience, and they not only swelled the ranks of membership, but often formed their own clubs, helping to expand nudism from coast to coast.

Most of those clubs united in the Canadian Sunbathing Association, which affiliated with the American Sunbathing Association in 1954. Several disagreements between eastern and western members of the CSA resulted in the breakup of CSA into the Western Canadian Sunbathing Association (WCSA) and the Eastern Canadian Sunbathing Association (ECSA) in 1960. The ECSA endured much in-fighting over the next decade and a half, leading to its official demise in 1978. The WCSA continues today as the American Association for Nude Recreation – Western Canadian Region (www.aanr-wc.com), a region of the American Association for Nude Recreation (AANR) which itself was formerly known as the ASA.

In 1977 the Fédération québécoise de naturisme (FQN) was founded in Quebec, by Michel Vaïs, who had experienced European naturism at Montalivet. In 1985 the Federation of Canadian Naturists (FCN) was formed with the support of the FQN. In 1988 the FQN and FCN formed the FQN-FCN Union as the official Canadian representative in the International Naturist Federation (INF).

United States

In 1925, Katherine and Herman Shoshinki were familiar with nudism from Germany from 1918 to 1923. Kurt Barthel founded the American League for Physical Culture in 1929 and organized the first nudist event. In about 1930 they organized the American Gymnosophical Association. Barthel founded America's first official nudist camp, Sky Farm in New Jersey, in May, 1932. Around 1932, AGA established the Rock Lodge Club as a nudist facility in Stockholm, New Jersey and Ilsley Boone, a Dutch Reformed minister, formed the Christian naturism movement. Naturism began expanding nationwide. Nudism venues were teetotal until 1970.

The American Association for Nude Recreation (AANR) is the national naturist organization. Arnd Krüger compared nudists in Germany and the United States and came to the conclusion that in Germany the racial aspects (Zuchtwahl) were important for the breakthrough (e.g. the Commanding General of the Army served as patron for nudists events), while in the U.S. nudism was far more commercial and had thus more difficulties. The AANR withdrew from the INF in 2010.

In 2008, a young adults group organized as Florida Young Naturists held their first Naked Bash which has since been repeated 3-4 times a year, growing into one of the largest young naturist gatherings in the world.

In 2009, a campaign to promote Nudism in the United States occurred with an effort by AANR to record the largest simultaneous Skinny Dip at several U.S. Clubs and beaches, occurring on July 11 of that year.

In 2010, A new organization formed called Young Naturists and Nudists America which was mostly focused around the younger generation as well as social issues, such as body image. Young Naturists and Nudists America closed in 2017.

In 2014, an organization called Unconstitutional Arkansas was created to highlight the unconstitutionality of laws that prohibit or impede nudism. The organization uses Arkansas law § 5-68-204 as a case study, but claims all anti-nudism laws infringe the constitutional right to assemble.

Mexico

Banner announcing 2016 legalization of nudity at Playa Zipolite

Beach nudity in Playa Zipolite is legal. Elsewhere, Mexican law condemns only "immorality" and thus the issue ends up being a matter of the judge's discretion. Private libertine/lifestyle type resorts exist in Mexico that might not be characterized as Naturist.

Zipolite, Oaxaca As of 2016, Playa Zipolite is Mexico's first and only legal public nude beach. A "free beach" and unofficially nudist for more than 30 years, this beach is reputed to be the best place for nudism in the country. The numerous nudists, and the long tradition, make it safe for nudism and naturism. Annually since 2016, on the first weekend of February, Zipolite has hosted Festival Nudista Zipolite organized by the Federación Nudista de México.
  • Hotel Nude is Zipolite's first nude-optional resort/hotel.

In Asia

Generally, public nudity in Asia is not tolerated. However, some traditional, religious or cultural nudity has survived the introduction of Western moral values against nudity, such as the Jain Digambara monks in India, hot springs in Taiwan and Japan, and some traditional tribes in Papua. Nudism and naked recreation is slowly developing in some countries, mainly Indonesia (Bali) and Thailand. Nudists meet on the internet (e.g. Bareskinasia.com) and organize activities in remote or private locations. Several nudists also have their own blogs.

Indonesia

In the seventies, nudity on Bali's remote and deserted beaches was common but with the massive growth of tourism, this practice has disappeared. In 2002, nudity was declared illegal on Petitenget Beach, the last beach in Seminyak that tolerated discreet nudity. Individuals began to practice nudity in private villas and resorts. Laki Uma Villa, the first naturist facility to open, was for gay men only. Bali au Naturel, the first adult-only nudist resort for both genders, opened its doors in 2004. It subsequently expanded from 3 to 15 rooms and added from two more swimming pools.

Nepal

Nudism is considered taboo in Nepal. Although there are no laws governing nudism, people may be detained, arrested and fined for public nudity. Nevertheless, many Hindu male sages practice nudism and they are not legally detained. Nudist sages can be seen in Pashupatinath.

Thailand

Nudism was successfully introduced in 10 years ago Pattaya (Chan Resort), and six more nudist resorts have been created all over Thailand. Barefeet Resort in Bangkok, Lemon Tree in Phuket, Oriental Village in Chiangmai, Phuan Naturist Village in Huay Yai, and Family Naturist Camp in Petchaburi all belong to the Naturist Association of Thailand as well as other international naturist organizations. A gay hotel and sauna (Sansuk Hotel) located in Pattaya now also authorizes nudity in and around the swimming pool.

Issues in social nudity

Naturism addresses, challenges and explores a myriad of sometimes taboo subjects: stereotypes and mores relating to the nude appearance of the human body, mixed sex nudity, personal space, human sexuality, gymnophobia, modesty, physical attractiveness, vanity, objectification, exploitation and consent. It can thus be controversial. Descamps assembled a list of criticisms of naturism: it is too cold; normal bodies look ugly—it is only for the physically beautiful; it is too embarrassing; it is against the laws of nature, against the law, or against religion; "nudism makes me think of sex"; it is for primitive people or animals.

Naturism can sometimes contain aspects of eroticism, although the debate about this is often simplified and seen negatively in the media and the public mind and by many modern naturists and naturist organisations. Historically the experience and discussion of erotic feelings during naturist activities such as dance and gymnastics played an important part in early Germanic naturism and formed part of its 'positive' connection with nature. However, it was when naturism arrived in the more sexually conservative cultures of the UK and the United States that the expression and discussion of eroticism within naturism became frowned upon.

Smith states
the main reason younger people are not becoming naturists is the inability of modern naturism to engage with the issue of sexuality. While it is true that "naturism became popular in Germany...as a healthy outdoor lifestyle", this lifestyle also included a recognition that, socially, nudity could sometimes be erotic. It was only when naturism arrived in a more sexually conservative Britain that sexual feelings were censored out to make naturism culturally acceptable.
This statement is in response to the quote "The world of naturism is in trouble. Membership is falling, and fewer young people than ever are getting involved. Has the great nude adventure run its course?"

Smith and King pose the further points in their 2009 peer reviewed paper Naturism and Sexuality:broadening our approach to sexual wellbeing. 

Issues for the naturist community

Many countries and states have laws which adversely affect naturists. Oftentimes, these laws are intended to address "indecent exposure", but are so broadly written that they criminalize ordinary, non-sexual nudity. Some laws, however, specifically target naturism. For example, in Arkansas in the United States, not only is nudism illegal (even on private property), it is a crime to "promote" or "advocate" (i.e. express a favourable opinion about) nudism.

Any social group is said to go through four phases: forming, storming, norming, performing, wrote Bruce Tuckman in 1965. In this context one can understand some of the current pressures on various aspects of naturism:
  • Naturist club isolation: established clubs excluding new members and rejecting new ideas.
  • A family movement in a time of social change: a change in needs and expectations, away from one of a permanent commitment towards one of change and choice.
  • Multi-gen preferences: each generation is a specific social group which needs to have its own norms that are consistent with common rules.
  • Clubs vs. holiday centres: organizations with different roots find it difficult to establish common rules. The contention between those espousing a year-round commitment to an ideal, and those who see it as summer-only recreation. Club naturism is declining, while the number of people that assume naturist facilities will be available at any holiday resort is rising. The number of users of free beaches may exceed the number of people who wish to join a club.
  • Paid staff and volunteers: many clubs were established as cooperatives, but the values change when a few members put in the capital or work needed. This became more difficult when some members were paid to act as site managers.
  • Infiltration by other groups: for many years clubs had strict "No singles" policies to maintain the family nature of the club. Many other social groups practice non-family nudism, whether it be social singles, gay naturists or swingers.
  • Exhibitionists and voyeurs: as unwelcome in a naturist community as in a clothed community.
  • Risk of being filmed in nude without permission, such as at nude beach. Such photos and videos can then be put on internet.
  • Sunburn and skin cancer.
  • Large numbers of clothed people visit clothing optional and nudist beaches and make the naturists feel uncomfortable, "like they've become a spectacle".
  • An issue, a decade ago in naturist resorts like Cap d'Agde has been the clash between "fundamentalist" naturists and the échangistes who are sexually open on the naturist beaches and bars.

Magazines

Magazines published by, for or purportedly about naturists can be grouped:
  • Magazines published by an "official" national organisation, such as BN (British Naturism), Going Natural/Au naturel (FCN/FQN), Nude & Natural Magazine TNS, gonatural (New Zealand Naturist Federation).
  • Independent magazines published for naturists, such as Naturally, H&E naturist and TAN (acronym of The Australian Naturist).
  • Magazines that print photographs only or primarily of young female professional models, which are disapproved of by many naturists and non-naturists alike.
Magazines in the second and, occasionally, third grouping feature naturist editorial and advertising, while some naturists argue over which magazines belonged in which of these categories – these views may change as publishers and editors change. Many clubs and groups have benefitted from magazines which, while not exclusively or even predominantly naturist in character, made naturist information available to many who would not otherwise have been aware of it. (These days, the information and advertising provided online, and the wide availability of free online porn, has meant the disappearance of old-style 'skin' magazines presenting significant glamour content masquerading as or alongside naturist content. Naturist magazines have to appeal strongly to naturists to succeed – they cannot sit on the fence between naturism and glamour.) Some naturists still feel that the worthwhile editorial content in some magazines is not a fair balance for the disapproved-of photographic content.

Photography, films and videos

Some naturist clubs have been willing to allow filming by the media on their grounds, though content that proved not to be of genuine naturism can end up being parodied by the media as the norm.

Some commercial 'naturist' DVDs are dominated by imagery of naked children. Such material can be marketed in ways that appear to appeal directly to paedophile inclinations, and ownership of these DVDs (and their earlier video cassette incarnations) has resulted in successful British prosecutions for possession of indecent images of children. One case was appealed, unsuccessfully, to the European Court of Human Rights. The precedents set by the court cases mean that possession in Britain of any naturist image of a child is, potentially, grounds for prosecution.

Photo shoots, including major high-profile works by Spencer Tunick, are done on public places including beaches.

Nature

Nature, in the broadest sense, is the natural, physical, or material world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena.

The word nature is derived from the Latin word natura, or "essential qualities, innate disposition", and in ancient times, literally meant "birth". Natura is a Latin translation of the Greek word physis (φύσις), which originally related to the intrinsic characteristics that plants, animals, and other features of the world develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socratic philosophers, and has steadily gained currency ever since. This usage continued during the advent of modern scientific method in the last several centuries.

Within the various uses of the word today, "nature" often refers to geology and wildlife. Nature can refer to the general realm of living plants and animals, and in some cases to the processes associated with inanimate objects–the way that particular types of things exist and change of their own accord, such as the weather and geology of the Earth. It is often taken to mean the "natural environment" or wilderness–wild animals, rocks, forest, and in general those things that have not been substantially altered by human intervention, or which persist despite human intervention. For example, manufactured objects and human interaction generally are not considered part of nature, unless qualified as, for example, "human nature" or "the whole of nature". This more traditional concept of natural things which can still be found today implies a distinction between the natural and the artificial, with the artificial being understood as that which has been brought into being by a human consciousness or a human mind. Depending on the particular context, the term "natural" might also be distinguished from the unnatural or the supernatural.

Earth

View of the Earth, taken in 1972 by the crew of Apollo 17.

Earth is the only planet known to support life, and its natural features are the subject of many fields of scientific research. Within the solar system, it is third closest to the sun; it is the largest terrestrial planet and the fifth largest overall. Its most prominent climatic features are its two large polar regions, two relatively narrow temperate zones, and a wide equatorial tropical to subtropical region. Precipitation varies widely with location, from several metres of water per year to less than a millimetre. 71 percent of the Earth's surface is covered by salt-water oceans. The remainder consists of continents and islands, with most of the inhabited land in the Northern Hemisphere.

Earth has evolved through geological and biological processes that have left traces of the original conditions. The outer surface is divided into several gradually migrating tectonic plates. The interior remains active, with a thick layer of plastic mantle and an iron-filled core that generates a magnetic field. This iron core is composed of a solid inner phase, and a fluid outer phase. Convective motion in the core generates electric currents through dynamo action, and these, in turn, generate the geomagnetic field.

The atmospheric conditions have been significantly altered from the original conditions by the presence of life-forms, which create an ecological balance that stabilizes the surface conditions. Despite the wide regional variations in climate by latitude and other geographic factors, the long-term average global climate is quite stable during interglacial periods, and variations of a degree or two of average global temperature have historically had major effects on the ecological balance, and on the actual geography of the Earth.

Geology

Geology is the science and study of the solid and liquid matter that constitutes the Earth. The field of geology encompasses the study of the composition, structure, physical properties, dynamics, and history of Earth materials, and the processes by which they are formed, moved, and changed. The field is a major academic discipline, and is also important for mineral and hydrocarbon extraction, knowledge about and mitigation of natural hazards, some Geotechnical engineering fields, and understanding past climates and environments.

Geological evolution

Three types of geological plate tectonic boundaries.

The geology of an area evolves through time as rock units are deposited and inserted and deformational processes change their shapes and locations.

Rock units are first emplaced either by deposition onto the surface or intrude into the overlying rock. Deposition can occur when sediments settle onto the surface of the Earth and later lithify into sedimentary rock, or when as volcanic material such as volcanic ash or lava flows, blanket the surface. Igneous intrusions such as batholiths, laccoliths, dikes, and sills, push upwards into the overlying rock, and crystallize as they intrude.

After the initial sequence of rocks has been deposited, the rock units can be deformed and/or metamorphosed. Deformation typically occurs as a result of horizontal shortening, horizontal extension, or side-to-side (strike-slip) motion. These structural regimes broadly relate to convergent boundaries, divergent boundaries, and transform boundaries, respectively, between tectonic plates.

Historical perspective

An animation showing the movement of the continents from the separation of Pangaea until the present day.

Earth is estimated to have formed 4.54 billion years ago from the solar nebula, along with the Sun and other planets. The moon formed roughly 20 million years later. Initially molten, the outer layer of the Earth cooled, resulting in the solid crust. Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, most or all of which came from ice delivered by comets, produced the oceans and other water sources. The highly energetic chemistry is believed to have produced a self-replicating molecule around 4 billion years ago.

Plankton inhabit oceans, seas and lakes, and have existed in various forms for at least 2 billion years.

Continents formed, then broke up and reformed as the surface of Earth reshaped over hundreds of millions of years, occasionally combining to make a supercontinent. Roughly 750 million years ago, the earliest known supercontinent Rodinia, began to break apart. The continents later recombined to form Pannotia which broke apart about 540 million years ago, then finally Pangaea, which broke apart about 180 million years ago.

During the Neoproterozoic era, freezing temperatures covered much of the Earth in glaciers and ice sheets. This hypothesis has been termed the "Snowball Earth", and it is of particular interest as it precedes the Cambrian explosion in which multicellular life forms began to proliferate about 530–540 million years ago.

Since the Cambrian explosion there have been five distinctly identifiable mass extinctions. The last mass extinction occurred some 66 million years ago, when a meteorite collision probably triggered the extinction of the non-avian dinosaurs and other large reptiles, but spared small animals such as mammals. Over the past 66 million years, mammalian life diversified.

Several million years ago, a species of small African ape gained the ability to stand upright. The subsequent advent of human life, and the development of agriculture and further civilization allowed humans to affect the Earth more rapidly than any previous life form, affecting both the nature and quantity of other organisms as well as global climate. By comparison, the Great Oxygenation Event, produced by the proliferation of algae during the Siderian period, required about 300 million years to culminate.

The present era is classified as part of a mass extinction event, the Holocene extinction event, the fastest ever to have occurred. Some, such as E. O. Wilson of Harvard University, predict that human destruction of the biosphere could cause the extinction of one-half of all species in the next 100 years. The extent of the current extinction event is still being researched, debated and calculated by biologists.

Atmosphere, climate, and weather

Blue light is scattered more than other wavelengths by the gases in the atmosphere, giving the Earth a blue halo when seen from space

The Earth's atmosphere is a key factor in sustaining the ecosystem. The thin layer of gases that envelops the Earth is held in place by gravity. Air is mostly nitrogen, oxygen, water vapor, with much smaller amounts of carbon dioxide, argon, etc. The atmospheric pressure declines steadily with altitude. The ozone layer plays an important role in depleting the amount of ultraviolet (UV) radiation that reaches the surface. As DNA is readily damaged by UV light, this serves to protect life at the surface. The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes.

Terrestrial weather occurs almost exclusively in the lower part of the atmosphere, and serves as a convective system for redistributing heat. Ocean currents are another important factor in determining climate, particularly the major underwater thermohaline circulation which distributes heat energy from the equatorial oceans to the polar regions. These currents help to moderate the differences in temperature between winter and summer in the temperate zones. Also, without the redistributions of heat energy by the ocean currents and atmosphere, the tropics would be much hotter, and the polar regions much colder.


Weather can have both beneficial and harmful effects. Extremes in weather, such as tornadoes or hurricanes and cyclones, can expend large amounts of energy along their paths, and produce devastation. Surface vegetation has evolved a dependence on the seasonal variation of the weather, and sudden changes lasting only a few years can have a dramatic effect, both on the vegetation and on the animals which depend on its growth for their food.

Climate is a measure of the long-term trends in the weather. Various factors are known to influence the climate, including ocean currents, surface albedo, greenhouse gases, variations in the solar luminosity, and changes to the Earth's orbit. Based on historical records, the Earth is known to have undergone drastic climate changes in the past, including ice ages.

A tornado in central Oklahoma

The climate of a region depends on a number of factors, especially latitude. A latitudinal band of the surface with similar climatic attributes forms a climate region. There are a number of such regions, ranging from the tropical climate at the equator to the polar climate in the northern and southern extremes. Weather is also influenced by the seasons, which result from the Earth's axis being tilted relative to its orbital plane. Thus, at any given time during the summer or winter, one part of the Earth is more directly exposed to the rays of the sun. This exposure alternates as the Earth revolves in its orbit. At any given time, regardless of season, the northern and southern hemispheres experience opposite seasons.

Weather is a chaotic system that is readily modified by small changes to the environment, so accurate weather forecasting is limited to only a few days. Overall, two things are happening worldwide: (1) temperature is increasing on the average; and (2) regional climates have been undergoing noticeable changes.

Water on Earth

The Iguazu Falls on the border between Brazil and Argentina

Water is a chemical substance that is composed of hydrogen and oxygen and is vital for all known forms of life. In typical usage, water refers only to its liquid form or state, but the substance also has a solid state, ice, and a gaseous state, water vapor, or steam. Water covers 71% of the Earth's surface. On Earth, it is found mostly in oceans and other large bodies of water, with 1.6% of water below ground in aquifers and 0.001% in the air as vapor, clouds, and precipitation. Oceans hold 97% of surface water, glaciers, and polar ice caps 2.4%, and other land surface water such as rivers, lakes, and ponds 0.6%. Additionally, a minute amount of the Earth's water is contained within biological bodies and manufactured products.

Oceans

A view of the Atlantic Ocean from Leblon, Rio de Janeiro.

An ocean is a major body of saline water, and a principal component of the hydrosphere. Approximately 71% of the Earth's surface (an area of some 361 million square kilometers) is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas. More than half of this area is over 3,000 meters (9,800 feet) deep. Average oceanic salinity is around 35 parts per thousand (ppt) (3.5%), and nearly all seawater has a salinity in the range of 30 to 38 ppt. Though generally recognized as several 'separate' oceans, these waters comprise one global, interconnected body of salt water often referred to as the World Ocean or global ocean. This concept of a global ocean as a continuous body of water with relatively free interchange among its parts is of fundamental importance to oceanography.

The major oceanic divisions are defined in part by the continents, various archipelagos, and other criteria: these divisions are (in descending order of size) the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean, and the Arctic Ocean. Smaller regions of the oceans are called seas, gulfs, bays and other names. There are also salt lakes, which are smaller bodies of landlocked saltwater that are not interconnected with the World Ocean. Two notable examples of salt lakes are the Aral Sea and the Great Salt Lake.

Lakes

Lake Mapourika, New Zealand

A lake (from Latin lacus) is a terrain feature (or physical feature), a body of liquid on the surface of a world that is localized to the bottom of basin (another type of landform or terrain feature; that is, it is not global) and moves slowly if it moves at all. On Earth, a body of water is considered a lake when it is inland, not part of the ocean, is larger and deeper than a pond, and is fed by a river. The only world other than Earth known to harbor lakes is Titan, Saturn's largest moon, which has lakes of ethane, most likely mixed with methane. It is not known if Titan's lakes are fed by rivers, though Titan's surface is carved by numerous river beds. Natural lakes on Earth are generally found in mountainous areas, rift zones, and areas with ongoing or recent glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world, there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them.

Ponds

The Westborough Reservoir (Mill Pond) in Westborough, Massachusetts.

A pond is a body of standing water, either natural or man-made, that is usually smaller than a lake. A wide variety of man-made bodies of water are classified as ponds, including water gardens designed for aesthetic ornamentation, fish ponds designed for commercial fish breeding, and solar ponds designed to store thermal energy. Ponds and lakes are distinguished from streams via current speed. While currents in streams are easily observed, ponds and lakes possess thermally driven micro-currents and moderate wind driven currents. These features distinguish a pond from many other aquatic terrain features, such as stream pools and tide pools.

Rivers

A river is a natural watercourse, usually freshwater, flowing toward an ocean, a lake, a sea or another river. In a few cases, a river simply flows into the ground or dries up completely before reaching another body of water. Small rivers may also be called by several other names, including stream, creek, brook, rivulet, and rill; there is no general rule that defines what can be called a river. Many names for small rivers are specific to geographic location; one example is Burn in Scotland and North-east England. Sometimes a river is said to be larger than a creek, but this is not always the case, due to vagueness in the language. A river is part of the hydrological cycle. Water within a river is generally collected from precipitation through surface runoff, groundwater recharge, springs, and the release of stored water in natural ice and snowpacks (i.e., from glaciers).

Streams

A stream is a flowing body of water with a current, confined within a bed and stream banks. In the United States, a stream is classified as a watercourse less than 60 feet (18 metres) wide. Streams are important as conduits in the water cycle, instruments in groundwater recharge, and they serve as corridors for fish and wildlife migration. The biological habitat in the immediate vicinity of a stream is called a riparian zone. Given the status of the ongoing Holocene extinction, streams play an important corridor role in connecting fragmented habitats and thus in conserving biodiversity. The study of streams and waterways in general involves many branches of inter-disciplinary natural science and engineering, including hydrology, fluvial geomorphology, aquatic ecology, fish biology, riparian ecology, and others.

Ecosystems

Ecosystems are composed of a variety of abiotic and biotic components that function in an interrelated way. The structure and composition is determined by various environmental factors that are interrelated. Variations of these factors will initiate dynamic modifications to the ecosystem. Some of the more important components are: soil, atmosphere, radiation from the sun, water, and living organisms.

Central to the ecosystem concept is the idea that living organisms interact with every other element in their local environment. Eugene Odum, a founder of ecology, stated: "Any unit that includes all of the organisms (ie: the "community") in a given area interacting with the physical environment so that a flow of energy leads to clearly defined trophic structure, biotic diversity, and material cycles (i.e.: exchange of materials between living and nonliving parts) within the system is an ecosystem." Within the ecosystem, species are connected and dependent upon one another in the food chain, and exchange energy and matter between themselves as well as with their environment. The human ecosystem concept is based on the human/nature dichotomy and the idea that all species are ecologically dependent on each other, as well as with the abiotic constituents of their biotope.

A smaller unit of size is called a microecosystem. For example, a microsystem can be a stone and all the life under it. A macroecosystem might involve a whole ecoregion, with its drainage basin.

Wilderness


Wilderness is generally defined as areas that have not been significantly modified by human activity. Wilderness areas can be found in preserves, estates, farms, conservation preserves, ranches, national forests, national parks, and even in urban areas along rivers, gulches, or otherwise undeveloped areas. Wilderness areas and protected parks are considered important for the survival of certain species, ecological studies, conservation, and solitude. Some nature writers believe wilderness areas are vital for the human spirit and creativity, and some ecologists consider wilderness areas to be an integral part of the Earth's self-sustaining natural ecosystem (the biosphere). They may also preserve historic genetic traits and that they provide habitat for wild flora and fauna that may be difficult or impossible to recreate in zoos, arboretums, or laboratories.

Life

Although there is no universal agreement on the definition of life, scientists generally accept that the biological manifestation of life is characterized by organization, metabolism, growth, adaptation, response to stimuli, and reproduction. Life may also be said to be simply the characteristic state of organisms.

Properties common to terrestrial organisms (plants, animals, fungi, protists, archaea, and bacteria) are that they are cellular, carbon-and-water-based with complex organization, having a metabolism, a capacity to grow, respond to stimuli, and reproduce. An entity with these properties is generally considered life. However, not every definition of life considers all of these properties to be essential. Human-made analogs of life may also be considered to be life.

The biosphere is the part of Earth's outer shell – including land, surface rocks, water, air and the atmosphere – within which life occurs, and which biotic processes in turn alter or transform. From the broadest geophysiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere (rocks), hydrosphere (water), and atmosphere (air). The entire Earth contains over 75 billion tons (150 trillion pounds or about 6.8×1013 kilograms) of biomass (life), which lives within various environments within the biosphere.

Over nine-tenths of the total biomass on Earth is plant life, on which animal life depends very heavily for its existence. More than 2 million species of plant and animal life have been identified to date, and estimates of the actual number of existing species range from several million to well over 50 million. The number of individual species of life is constantly in some degree of flux, with new species appearing and others ceasing to exist on a continual basis. The total number of species is in rapid decline.

Evolution

An area of the Amazon Rainforest shared between Colombia and Brazil. The tropical rainforests of South America contain the largest diversity of species on Earth.

The origin of life on Earth is not well understood, but it is known to have occurred at least 3.5 billion years ago, during the hadean or archean eons on a primordial Earth that had a substantially different environment than is found at present. These life forms possessed the basic traits of self-replication and inheritable traits. Once life had appeared, the process of evolution by natural selection resulted in the development of ever-more diverse life forms.

Species that were unable to adapt to the changing environment and competition from other life forms became extinct. However, the fossil record retains evidence of many of these older species. Current fossil and DNA evidence shows that all existing species can trace a continual ancestry back to the first primitive life forms.

When basic forms of plant life developed the process of photosynthesis the sun's energy could be harvested to create conditions which allowed for more complex life forms. The resultant oxygen accumulated in the atmosphere and gave rise to the ozone layer. The incorporation of smaller cells within larger ones resulted in the development of yet more complex cells called eukaryotes. Cells within colonies became increasingly specialized, resulting in true multicellular organisms. With the ozone layer absorbing harmful ultraviolet radiation, life colonized the surface of Earth.

Microbes

The first form of life to develop on the Earth were microbes, and they remained the only form of life until about a billion years ago when multi-cellular organisms began to appear. Microorganisms are single-celled organisms that are generally microscopic, and smaller than the human eye can see. They include Bacteria, Fungi, Archaea, and Protista.

These life forms are found in almost every location on the Earth where there is liquid water, including in the Earth's interior. Their reproduction is both rapid and profuse. The combination of a high mutation rate and a horizontal gene transfer ability makes them highly adaptable, and able to survive in new environments, including outer space. They form an essential part of the planetary ecosystem. However, some microorganisms are pathogenic and can post health risk to other organisms.

Plants and animals

Originally Aristotle divided all living things between plants, which generally do not move fast enough for humans to notice, and animals. In Linnaeus' system, these became the kingdoms Vegetabilia (later Plantae) and Animalia. Since then, it has become clear that the Plantae as originally defined included several unrelated groups, and the fungi and several groups of algae were removed to new kingdoms. However, these are still often considered plants in many contexts. Bacterial life is sometimes included in flora, and some classifications use the term bacterial flora separately from plant flora.

Among the many ways of classifying plants are by regional floras, which, depending on the purpose of study, can also include fossil flora, remnants of plant life from a previous era. People in many regions and countries take great pride in their individual arrays of characteristic flora, which can vary widely across the globe due to differences in climate and terrain.

Regional floras commonly are divided into categories such as native flora and agricultural and garden flora, the lastly mentioned of which are intentionally grown and cultivated. Some types of "native flora" actually have been introduced centuries ago by people migrating from one region or continent to another, and become an integral part of the native, or natural flora of the place to which they were introduced. This is an example of how human interaction with nature can blur the boundary of what is considered nature.

Another category of plant has historically been carved out for weeds. Though the term has fallen into disfavor among botanists as a formal way to categorize "useless" plants, the informal use of the word "weeds" to describe those plants that are deemed worthy of elimination is illustrative of the general tendency of people and societies to seek to alter or shape the course of nature. Similarly, animals are often categorized in ways such as domestic, farm animals, wild animals, pests, etc. according to their relationship to human life.

Animals as a category have several characteristics that generally set them apart from other living things. Animals are eukaryotic and usually multicellular (although see Myxozoa), which separates them from bacteria, archaea, and most protists. They are heterotrophic, generally digesting food in an internal chamber, which separates them from plants and algae. They are also distinguished from plants, algae, and fungi by lacking cell walls.

With a few exceptions—most notably the two phyla consisting of sponges and placozoans—animals have bodies that are differentiated into tissues. These include muscles, which are able to contract and control locomotion, and a nervous system, which sends and processes signals. There is also typically an internal digestive chamber. The eukaryotic cells possessed by all animals are surrounded by a characteristic extracellular matrix composed of collagen and elastic glycoproteins. This may be calcified to form structures like shells, bones, and spicules, a framework upon which cells can move about and be reorganized during development and maturation, and which supports the complex anatomy required for mobility.

Human interrelationship

Despite their natural beauty, the secluded valleys along the Na Pali Coast in Hawaii are heavily modified by introduced invasive species such as She-oak.

Although humans comprise only a minuscule proportion of the total living biomass on Earth, the human effect on nature is disproportionately large. Because of the extent of human influence, the boundaries between what humans regard as nature and "made environments" is not clear cut except at the extremes. Even at the extremes, the amount of natural environment that is free of discernible human influence is diminishing at an increasingly rapid pace.

The development of technology by the human race has allowed the greater exploitation of natural resources and has helped to alleviate some of the risk from natural hazards. In spite of this progress, however, the fate of human civilization remains closely linked to changes in the environment. There exists a highly complex feedback loop between the use of advanced technology and changes to the environment that are only slowly becoming understood. Man-made threats to the Earth's natural environment include pollution, deforestation, and disasters such as oil spills. Humans have contributed to the extinction of many plants and animals.

Humans employ nature for both leisure and economic activities. The acquisition of natural resources for industrial use remains a sizable component of the world's economic system. Some activities, such as hunting and fishing, are used for both sustenance and leisure, often by different people. Agriculture was first adopted around the 9th millennium BCE. Ranging from food production to energy, nature influences economic wealth.

Although early humans gathered uncultivated plant materials for food and employed the medicinal properties of vegetation for healing, most modern human use of plants is through agriculture. The clearance of large tracts of land for crop growth has led to a significant reduction in the amount available of forestation and wetlands, resulting in the loss of habitat for many plant and animal species as well as increased erosion.

Aesthetics and beauty

Beauty in nature has historically been a prevalent theme in art and books, filling large sections of libraries and bookstores. That nature has been depicted and celebrated by so much art, photography, poetry, and other literature shows the strength with which many people associate nature and beauty. Reasons why this association exists, and what the association consists of, are studied by the branch of philosophy called aesthetics. Beyond certain basic characteristics that many philosophers agree about to explain what is seen as beautiful, the opinions are virtually endless. Nature and wildness have been important subjects in various eras of world history. An early tradition of landscape art began in China during the Tang Dynasty (618–907). The tradition of representing nature as it is became one of the aims of Chinese painting and was a significant influence in Asian art.

Although natural wonders are celebrated in the Psalms and the Book of Job, wilderness portrayals in art became more prevalent in the 1800s, especially in the works of the Romantic movement. British artists John Constable and J. M. W. Turner turned their attention to capturing the beauty of the natural world in their paintings. Before that, paintings had been primarily of religious scenes or of human beings. William Wordsworth's poetry described the wonder of the natural world, which had formerly been viewed as a threatening place. Increasingly the valuing of nature became an aspect of Western culture. This artistic movement also coincided with the Transcendentalist movement in the Western world. A common classical idea of beautiful art involves the word mimesis, the imitation of nature. Also in the realm of ideas about beauty in nature is that the perfect is implied through perfect mathematical forms and more generally by patterns in nature. As David Rothenburg writes, "The beautiful is the root of science and the goal of art, the highest possibility that humanity can ever hope to see".

Matter and energy

Some fields of science see nature as matter in motion, obeying certain laws of nature which science seeks to understand. For this reason the most fundamental science is generally understood to be "physics" – the name for which is still recognizable as meaning that it is the study of nature.

Matter is commonly defined as the substance of which physical objects are composed. It constitutes the observable universe. The visible components of the universe are now believed to compose only 4.9 percent of the total mass. The remainder is believed to consist of 26.8 percent cold dark matter and 68.3 percent dark energy. The exact arrangement of these components is still unknown and is under intensive investigation by physicists.

The behavior of matter and energy throughout the observable universe appears to follow well-defined physical laws. These laws have been employed to produce cosmological models that successfully explain the structure and the evolution of the universe we can observe. The mathematical expressions of the laws of physics employ a set of twenty physical constants that appear to be static across the observable universe. The values of these constants have been carefully measured, but the reason for their specific values remains a mystery.

Outer space, also simply called space, refers to the relatively empty regions of the universe outside the atmospheres of celestial bodies. Outer space is used to distinguish it from airspace (and terrestrial locations). There is no discrete boundary between the Earth's atmosphere and space, as the atmosphere gradually attenuates with increasing altitude. Outer space within the Solar System is called interplanetary space, which passes over into interstellar space at what is known as the heliopause.

Outer space is sparsely filled with several dozen types of organic molecules discovered to date by microwave spectroscopy, blackbody radiation left over from the big bang and the origin of the universe, and cosmic rays, which include ionized atomic nuclei and various subatomic particles. There is also some gas, plasma and dust, and small meteors. Additionally, there are signs of human life in outer space today, such as material left over from previous manned and unmanned launches which are a potential hazard to spacecraft. Some of this debris re-enters the atmosphere periodically.
Although the Earth is the only body within the solar system known to support life, evidence suggests that in the distant past the planet Mars possessed bodies of liquid water on the surface. For a brief period in Mars' history, it may have also been capable of forming life. At present though, most of the water remaining on Mars is frozen. If life exists at all on Mars, it is most likely to be located underground where liquid water can still exist.

Conditions on the other terrestrial planets, Mercury and Venus, appear to be too harsh to support life as we know it. But it has been conjectured that Europa, the fourth-largest moon of Jupiter, may possess a sub-surface ocean of liquid water and could potentially host life.

Astronomers have started to discover extrasolar Earth analogs – planets that lie in the habitable zone of space surrounding a star, and therefore could possibly host life as we know it.
