The concept of light pollution coalesced in the early 1970s, amid a climate of political activism, rising environmental awareness, and an energy crisis. In discussing lighting conflicts in Germany—but providing generally applicable conclusions—Hasenöhrl (2014 Hasenöhrl, U. (2014). Lighting conflicts from a historical perspective. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution, and society (pp. 105–124). New York, NY: Taylor & Francis. [Google Scholar], p. 119) notes that ‘it was not before the oil crises and the growing environmental and heritage movements of the 1970s that lighting as a particularly visible form of energy consumption and as an object of cultural value regained public and political attention’. Lighting, at this point a ubiquitious everyday experience, was given new attention but in a very different framework: that it is polluting the night sky. Sperling (1991 Sperling, N. (1991). The disappearance of darkness. In D. L. Crawford (Ed.), Light pollution, radio interference, and space debris (Vol. 17, pp. 101–108). San Francisco, CA: Astronomical Society of the Pacific Conference Series. [Google Scholar]) gives a brief narrative of the term’s popularization, explaining that in the politically charged atmosphere of the 1960s and 1970s astronomers began advocating for the curbing of excess lighting detrimental to starlight visibility. Then during the 1973 energy crisis urban areas saw an increase in energy conservation efforts, resulting in decreases to public lighting (Neumann, 2002b Neumann, D. (2002b). Architectural illumination since World War II. In D. Neumann (Ed.), Architecture of the night: The illuminated building (pp. 78–84). New York, NY: Prestel. [Google Scholar]). Astronomers used the anti-waste strategies of the time to fight excess artificial nighttime brightness, which is when, according to Sperling, ‘the struggle took on its current aspect’ (1991 Sperling, N. (1991). The disappearance of darkness. In D. L. Crawford (Ed.), Light pollution, radio interference, and space debris (Vol. 17, pp. 101–108). San Francisco, CA: Astronomical Society of the Pacific Conference Series. [Google Scholar], p. 103). Thus, it was an opportune moment for astronomers to advocate for the mitigation of certain aspects of nighttime lighting. Around this time a paper was published in Science titled ‘Light Pollution: Outdoor lighting is a growing threat to astronomy’ (Riegel, 1973 Riegel, K. W. (1973). Light pollution: Outdoor lighting is a growing threat to astronomy. Science, 179, 1285–1291.10.1126/science.179.4080.1285[Crossref], [PubMed], [Web of Science ®] [Google Scholar]), which seemingly marks the academic acceptance and adoption of the concept. Sometimes it is not possible to completely get rid of the problem, as this may prevent the street light from being effective so we may need to find a compromise. Few creationists have aggressively pursued solution one. The reasoning for this solution has been that if the distances of astronomical objects are not known that well, then astronomical bodies may be far closer than generally thought, and hence there is no light travel time problem. This solution amounts to defining the problem away, but there are additional problems with this solution. First, creationists who have suggested this solution do correctly point out that trigonometric parallax, the only direct method of measuring stellar distances, yields distances that at most are only a few hundred light years. So this could explain why we see all the stars for which we have directly determined distances. One might further reason that since the distance determination methods that give very great distances that cause the light travel time problem today are indirect, those indirect methods are somehow suspect. However, one cannot dismiss the indirect methods so easily. Most of these methods are based upon well understood physical principles, and many of the indirect methods are calibrated to trigonometric parallax. See Faulkner (2013) for a discussion of distance determination methods. Second, this solution relies upon the incorrectly formulated light travel time problem. While today we can see stars such as Alpha Centauri, the closest star similar to the sun, with this solution it would not have been visible to Adam at the conclusion of the Creation Week, because it is 4.3 light years away. For this solution to work, even the well determined trigonometric parallax method must be abandoned, but this is not physically supported. Hello. Awhile ago i tried to take photo with my instax. Then the red light were blinking. I tried to change batteries and the red lighy disappeared but i couldnt take photos Several different types of light sources exist, each having different properties that affect their appropriateness for certain tasks, particularly efficiency and spectral power distribution. It is often the case that inappropriate light sources have been selected for a task, either due to ignorance or because more sophisticated light sources were unavailable at the time of installation. Therefore, badly chosen light sources often contribute unnecessarily to light pollution and energy waste. By re-assessing and changing the light sources used, it is often possible to reduce energy use and pollutive effects while simultaneously greatly improving efficiency and visibility. If the light bulb does not light up at all, follow this troubleshooting procedure: In establishing an acceptable level of polluting, some clarification of qualitative values will strengthen future decisions. Consider the research by Gallaway (2014 Gallaway, T. (2014). The value of the night sky. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution and society (pp. 267–283). New York, NY: Taylor & Francis. [Google Scholar]), who explores the instrumental value of the night sky for promoting the broadly held values of happiness and sustainability. He concludes by stating, ‘We suggest that estimating the night’s value is not nearly as important as simply recognizing that it does have enormous value and then trying to preserve this value and put it to good use’ (p. 280). Gallaway’s discussion of key night sky traits includes its ability to connect us to the natural world, its ability to engender a sense of wonder, and its beauty. Such an articulation of the value of reducing light pollution falls outside traditional economic calculations, as discussed elsewhere by Gallaway (2010 Gallaway, T. (2010). On light pollution, passive pleasures, and the instrumental value of beauty. Journal of Economic Issues, 44, 71–88.10.2753/JEI0021-3624440104[Taylor & Francis Online], [Web of Science ®] [Google Scholar]). It also further calls into question a needs-based approach. As a frame, light pollution will set the boundaries on what sort of answers are possible, which requires a careful consideration of how ‘needs’ are defined, and what needs ought to be encapsulated by future policies.

By an accident I turned off the camera when the picture wasn’t fully out and I pulled it out but now it flashes red loading lights and doesn’t even take pictures Apparent problems with a ceiling light fixture are usually traced to some issue that is interrupting the flow of electricity from the wall switch to the light fixture. Diagnosing the problem will depend on whether the light bulb does not light up at all, or if it is flickering intermittently.  Concerns have also remained regarding the inverse of proliferating nighttime lighting, namely the rapidly declining access to a natural night sky in the developed world. In recent decades attempts to quantify skyglow and its global presence have emerged, however, data is still somewhat sparse. The first attempt to map this phenomenon on a global scale was published by Cinzano et al. (2001 Cinzano, P., Falchi, F., & Elvidge, C. D. (2001). The first world Atlas of the artificial night sky brightness. Monthly Notices of the Royal Astronomical Society, 328, 689–707.10.1046/j.1365-8711.2001.04882.x[Crossref], [Web of Science ®] [Google Scholar]). A more recent study by Gallaway et al. (2010 Gallaway, T., Olsen, R., & Mitchell, D. (2010). The economics of global light pollution. Ecological Economics, 69, 658–665.10.1016/j.ecolecon.2009.10.003[Crossref], [Web of Science ®] [Google Scholar]) built on their findings and concluded that the amount of people living in areas with a ‘polluted night sky’ is extremely high: around 99% in both North America and the European Union.88. Gallaway et al. (2010 Gallaway, T., Olsen, R., & Mitchell, D. (2010). The economics of global light pollution. Ecological Economics, 69, 658–665.10.1016/j.ecolecon.2009.10.003[Crossref], [Web of Science ®] [Google Scholar]) utilize the threshold criteria established by Cinzano et al. (2001 Cinzano, P., Falchi, F., & Elvidge, C. D. (2001). The first world Atlas of the artificial night sky brightness. Monthly Notices of the Royal Astronomical Society, 328, 689–707.10.1046/j.1365-8711.2001.04882.x[Crossref], [Web of Science ®] [Google Scholar]) for considering an area ‘polluted’ by light. These criteria ‘consider the night sky polluted when the artificial brightness of the sky is greater than 10% of the natural sky brightness above 45° of elevation’ (Gallaway et al., 2010 Gallaway, T., Olsen, R., & Mitchell, D. (2010). The economics of global light pollution. Ecological Economics, 69, 658–665.10.1016/j.ecolecon.2009.10.003[Crossref], [Web of Science ®] [Google Scholar], p. 660).View all notes Furthermore, on both continents approximately 70% of the population lives in areas where brightness at night is at least three times natural levels. From a dark rural area, our unaided eyes can normally see up to 3,000 stars; people with strong eyesight can even see close to 7,000 stars. However, in many urban areas today this number is reduced to around 50, or perhaps even less (Mizon, 2012 Mizon, B. (2012). Light pollution: Responses and remedies (2nd ed.). New York, NY: Springer.10.1007/978-1-4614-3822-9[Crossref] [Google Scholar]). Researchers caution that if the current pace of increasing brightness continues, the ‘pristine night sky’ could become ‘extinct’ in the continental United States by 2025 (Fischer, 2011 Fischer, A. (2011). Starry night. Places Journal. Retrieved 22 October, 2014,. from https://placesjournal.org/article/starry-night/[Crossref] [Google Scholar]).
