Монреаль Биосферасы: Қоршаған орта музейі

Environment museum in Montreal, Quebec, Canada

The Biosphere, also known as the Montreal Biosphere, is a museum dedicated to the environment in Montreal, Quebec, Canada. It is housed in the former United States pavilion constructed for Expo 67 located within the grounds of Parc Jean Drapeau on Saint Helen's Island. The museum's geodesic dome was designed by Buckminster Fuller.

The structure was originally built as the United States pavilion at Expo 67. The United States Information Agency, which was responsible for the U. S. presence at the exposition, revealed its plans for the pavilion in June 1965. The geodesic dome exterior was designed by R. Buckminster Fuller with Shoji Sadao and Geometrics Inc., while the interior structures and exhibits were designed by Cambridge Seven Associates. The Expo opened on 27 April 1967 and ran until 29 October 1967. Upon entering the pavilion, visitors ascended a escalator, reported to be the longest unsupported escalator in the world, to reach the exhibit platforms. The two uppermost platforms held "Destination: Moon", an exhibit on NASA's space programs; spacecraft were hung from the dome's steel frame, including the Freedom 7, Gemini 7, and Apollo AS 202 capsules. On the mezzanine level, the "American Spirit" exhibit displayed a wide variety of artifacts, including American Indian crafts, folk art objects, guitars owned by famous musicians, a collection of dolls, and an array of almost 300 hats, representing a range of regions and occupations. Other attractions included a gallery of Hollywood memorabilia and "American Painting Now", an exhibit of 22 large scale works by contemporary American artists.

After the Expo, the site continued to operate as Man and His World, an ongoing exhibition held every summer. Like most countries at the Expo, the United States donated its pavilion structure to the City of Montreal for use in the exhibition. The pavilion was renamed to Biosphere and opened in 1968 as an aviary and arboretum, featuring four suspended gardens and hundreds of birds. For the 1971 season, the United States returned to use Biosphere as its national pavilion, with a display titled "Visit USA", sponsored by the United States Travel Service and the Smithsonian Institution. The pavilion reverted to its nature theme in 1972, with the addition of a troop of baboons, a Japanese garden, and a children's adventure area, Sleeping Beauty's Fantasy Land. In 1973, Biosphere was converted to an anti pollution exhibit titled "Man and His Environment", sponsored by Hydro Québec.

On 20 May 1976, Biosphere was severely damaged in a fire. Sparked by a welding crew during structural renovations, the fire burned away the building's transparent acrylic bubble, but the hard steel truss structure remained. After the fire, the city was determined to maintain the Biosphere and continue using it as an open air structure, possibly containing suspended gardens or a concert venue. Plans were announced in 1977 to transform it into a recreational area named Man at Play, but they did not come to fruition. By 1980, the building's future was still unclear, as the city was cleaning it up in hopes of finding a partner to redevelop it. Ultimately, the building remained closed and unused until 1990.

In August 1990, Environment Canada committed $17.5 million to turn Biosphere into an interactive museum showcasing and exploring the water ecosystems of the Great Lakes Saint Lawrence River regions. It inhabits a set of enclosed buildings designed by Éric Gauthier, inside the original steel skeleton. The Biosphere changed its name in 2007 to become an environment museum. It offers interactive activities and presents exhibitions about the major environmental issues related to water, climate change, air, ecotechnologies, and sustainable development. The museum shows support for multiple causes by lighting up in different colors on special occasions. In April 2020, it lit up in multiple colors to show support during the COVID 19 pandemic. In June 2022, the museum lit up in green in support of World Environment Day. In 2021, control of the Biosphere was transferred from Environment Canada to Space for Life, the City of Montreal's complex of nature museums.

The museum is housed in the former pavilion built by the United States for Expo 67. The architectural engineer of the geodesic dome was Buckminster Fuller. The building originally formed an enclosed structure of steel and acrylic cells, in diameter and high. It is a Class 1 (icosahedral, as differentiated from Class 2 domes, which are dodecahedral, and Class 3 ones, which are tetrahedral), 32 frequency, double layer dome, in which the inner and outer layers are connected by a latticework of struts. (There has occasionally been confusion in mistakenly referring to this as a 16 frequency dome due to the fact that there are 15 hexagonal polygons from each pentagonally polygonal vertex of this icosahedral polyhedron to the adjacent vertex. However, the standard for measuring dome frequency is the number of triangles from vertex to vertex. Since there are two triangles from one side to the opposite side of a hexagon, there are actually 30 triangles from the edge of each pentagonal vertex in this dome to the next, plus the triangle that comprises one fifth of the pentagonal vertex at each end of the length from one vertex to the adjacent vertex: totaling 32 triangles from the center of each vertex to the center of the next vertex.) A complex system of shades was used to control its internal temperature. The sun shading system was an attempt by the architect to reflect the same biological processes that the human body relies on to maintain its internal temperature. Fuller's original idea for the geodesic dome was to incorporate "pores" into the enclosed system, further likening it to the sensitivity of human skin, In 2021, The New York Times picked the dome as one of "the 25 Most Significant Works of Postwar Architecture".

The carbon molecule buckminsterfullerene was named for Biosphere's architect, R. Buckminster Fuller, because the molecule's structure, resembling a geodesic sphere, reminded its co discoverer, Harold Kroto, of his visit to the pavilion at Expo 67. The structure influenced the design of Spaceship Earth at EPCOT Center in Walt Disney World. Disney designer John Hench expanded on Biosphere's three quarter sphere to create a full sphere appearing to be balanced on legs. The Biosphere appears in the game Civilization VI (in the New Frontiers DLC) as a World Wonder, where it increases the appeal of marsh and rainforest tiles, and boosts renewable power and tourism.
