Dark-sky Movement
The dark-sky movement is a campaign to reduce light pollution. The advantages of reducing light pollution include an increased number of stars visible at night, reducing the effects of electric lighting on the environment, improving the well-being, health and safety of both people and wildlife, and cutting down on energy usage. Earth Hour and National Dark-Sky Week are two examples of such efforts. The movement started with professional and amateur astronomers alarmed that nocturnal skyglow from urban areas was blotting out the sight of stars. For example, the world-famous Palomar Observatory in California is threatened by sky-glow from the nearby city of Escondido and local businesses. For similar reasons, astronomers in Arizona helped push the governor there to veto a bill in 2012 which would have lifted a ban on illuminated billboards. Nocturnal animals can be harmed by light pollution because they are biologically evolved to be dependent on an environment with a certain numb ...

Social Movement
A social movement is a loosely organized effort by a large group of people to achieve a particular goal, typically a social or political one. This may be to carry out a social change, or to resist or undo one. It is a type of group action and may involve individuals, organizations, or both. Social movements have been described as "organizational structures and strategies that may empower oppressed populations to mount effective challenges and resist the more powerful and advantaged elites". They represent a method of social change from the bottom within nations. Political science and sociology have developed a variety of theories and empirical research on social movements. For example, some research in political science highlights the relation between popular movements and the formation of new political parties as well as discussing the function of social movements in relation to agenda setting and influence on politics. Sociologists distinguish between several types of social mov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunlight
Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon. When direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When blocked by clouds or reflected off other objects, sunlight is diffused. Sources estimate a global average of between 164 watts to 340 watts per square meter over a 24-hour day; this figure is estimated by NASA to be about a quarter of Earth's average total solar irradiance. The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a requisite for vitamin D3 synthesis and a mutagen. Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the center of the Sun and changing direction eve ...

Niue
Niue (, ; niu, Niuē) is an island country in the South Pacific Ocean, northeast of New Zealand. Niue's land area is about and its population, predominantly Polynesian, was about 1,600 in 2016. Niue is located in a triangle between Tonga, Samoa, and the Cook Islands. It is 604 kilometres northeast of Tonga. The island is commonly referred to as "The Rock", which comes from the traditional name "Rock of Polynesia". Niue is one of the world's largest coral islands. The terrain of the island has two noticeable levels. The higher level is made up of a limestone cliff running along the coast, with a plateau in the centre of the island reaching approximately 60 metres (200 feet) above sea level. The lower level is a coastal terrace approximately 0.5 km (0.3 miles) wide and about 25–27 metres (80–90 feet) high, which slopes down and meets the sea in small cliffs. A coral reef surrounds the island, with the only major break in the reef being in the central western c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Dark-Sky Association
The International Dark-Sky Association (IDA) is a United States-based non-profit organization incorporated in 1988 by founders David Crawford, a professional astronomer, and Tim Hunter, a physician/amateur astronomer. The mission of the IDA is "to preserve and protect the night time environment and our heritage of dark skies through quality outdoor lighting." Light pollution is the result of outdoor lighting that is not properly shielded, allowing light shine into the eyes and night sky. Direct light that shines into the eyes is called glare, and light directed into the night sky above the horizon causes skyglow. Lighting can also cause light trespass when it enters areas where unwanted (e.g. a neighbor's yard and windows). IDA was the first organization in the dark-sky movement, and is currently the largest. Principal approach IDA's principal approach is to raise awareness about the value of dark, star-filled night skies and encourage their protection and restoration through e ...

CieloBuio
CieloBuio-coordinamento per la protezione del cielo notturno (''Coordination for the protection of the night sky'') is a non-profit organization that operates in Italy for the protection of the night sky by promoting a culture of eco-friendly lighting and raising public awareness about the phenomenon of light pollution. Created in Lombardy in 1997 around a mailing-list of people interested in the topic of light pollution, CieloBuio now brings together professional and amateur astronomers, environmentalists, lighting engineers, and simply interested people throughout Italy. The current president is Dr. Fabio Falchi. In its fight against light pollution, CieloBuio has as a reference model to support and promote the law of the Lombardy region n. 17/2000, in all its forms and extensions. This law is based on the criterion of ''zero pollution'', according to which, with very few exceptions, no streetlamp can send light above the horizontal plane. CieloBuio in recent years has played ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Scotobiology Group
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World immigrants and their descendants. Following the initial period of French and then the much larger British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian identity. Canada has also been strongly influenced by its linguistic, geographic, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Campaign For Dark Skies
The Commission for Dark Skies (CfDS) (formerly the Campaign for Dark Skies; the name was changed on March 29, 2015) is the United Kingdom's largest anti- light-pollution campaign group forming part of the international dark-sky movement. It is run by the British Astronomical Association (BAA) and affiliated with the International Dark-Sky Association (IDA), and composed of a network olocal officers(and other members) who try to improve lighting in their areas and advise local people. The campaign was founded in 1989 by amateur astronomers as a sub-section of the BAA specialising in combatting skyglow. It is now open to non-members of the BAA, includes lighting engineers and environmentalists, and campaigns on the wider effects of light pollution. Legislation CfDS's work with the House of Commons Science and Technology Committee on legislating against light pollution has resulted in the government including provisions in their Clean Neighbourhoods and Environment Bill.

Merritt, British Columbia
Merritt is a city in the Nicola Valley of the south-central Interior of British Columbia, Canada. It is northeast of Vancouver. Situated at the confluence of the Nicola and Coldwater rivers, it is the first major community encountered after travelling along Phase One of the Coquihalla Highway and acts as the gateway to all other major highways to the B.C. Interior. The city developed in 1893 when part of the ranches owned by William Voght, Jesus Garcia, and John Charters were surveyed for a town site. Once known as Forksdale, the community adopted its current name in 1906 in honour of mining engineer and railway promoter William Hamilton Merritt III.Akrigg, Helen B. and Akrigg, G.P.V; 1001 British Columbia Place Names; Discovery Press, Vancouver 1969, 1970, 1973, p. 114 The city limits consist of the community, a number of civic parks, historical sites, an aquatic centre, a local arena, a public library (which is a branch of the Thompson-Nicola Regional District Library Sy ...
