When artificial light affects organisms and ecosystems it is called ecological light pollution. While light at night can be beneficial, neutral, or damaging for individual species, its presence invariably disturbs ecosystems. For example, some species of spiders avoid lit areas, while other species are happy to build their spider web directly on a lamp post. Since lamp posts attract many flying insects, the spiders that don’t mind light, gain an advantage over the spiders that avoid it. This is a simple example of the way in which species frequencies and food webs can be disturbed by the introduction of light at night. Akridge, G. R. 1984. The universe is bigger than 15.71 light years. Creation Research Society Quarterly 21, no. 1:18–22. Over-illumination is the excessive use of light. Specifically within the United States, over-illumination is responsible for approximately two million barrels of oil per day in energy wasted.[citation needed] This is based upon U.S. consumption of equivalent of 18.8 million barrels per day (2,990,000 m3/d) of petroleum.[16] It is further noted in the same U.S. Department of Energy source that over 30% of all primary energy is consumed by commercial, industrial and residential sectors. Energy audits of existing buildings demonstrate that the lighting component of residential, commercial and industrial uses consumes about 20–40% of those land uses, variable with region and land use. (Residential use lighting consumes only 10–30% of the energy bill while commercial buildings’ major use is lighting.[17]) Thus lighting energy accounts for about four or five million barrels of oil (equivalent) per day. Again energy audit data demonstrates that about 30–60% of energy consumed in lighting is unneeded or gratuitous.[18] Tell us about problems with street lights, pedestrian crossings or illuminated bollards: Please note that street lights are fixed as soon as possible, depending upon when crews are in the area and workload. Disadvantages of low pressure sodium lighting are that fixtures must usually be larger than competing fixtures, and that color cannot be distinguished, due to its emitting principally a single wavelength of light (see security lighting). Due to the substantial size of the lamp, particularly in higher wattages such as 135 W and 180 W, control of light emissions from low pressure sodium luminaires is more difficult. For applications requiring more precise direction of light (such as narrow roadways) the native lamp efficacy advantage of this lamp type is decreased and may be entirely lost compared to high pressure sodium lamps. Allegations that this also leads to higher amounts of light pollution from luminaires running these lamps arise principally because of older luminaires with poor shielding, still widely in use in the UK and in some other locations. Modern low-pressure sodium fixtures with better optics and full shielding, and the decreased skyglow impacts of yellow light preserve the luminous efficacy advantage of low-pressure sodium and result in most cases is less energy consumption and less visible light pollution. Unfortunately, due to continued lack of accurate information,[92] many lighting professionals continue to disparage low-pressure sodium, contributing to its decreased acceptance and specification in lighting standards and therefore its use. Another disadvantage of low-pressure sodium lamps is that some people find the characteristic yellow light very displeasing aesthetically.[citation needed] I have outwalked the furthest city light, ends the first stanza of Robert Frost’s poem ‘Acquainted with the Night’. For many contemporary urban dwellers, such a feat is becoming exceedingly difficult in our electrified, 24 h societies. While artificial nighttime illumination has brought with it many advances and possibilities, the negative consequences of its ubiquity and proliferation have only recently emerged as a topic of inquiry. Discourse is increasingly framing concerns about nighttime lighting via the concept of light pollution, particularly with respect to environmental effects. However, light pollution has received relatively little attention compared to other environmental problems, remaining scientifically and culturally ‘in the dark’ (Hölker et al., 2010 Hölker, F., Moss, T., Griefahn, B., Kloas, W., Voigt, C., Henckel, D., … Tockner, K. (2010). The dark side of light: A transdisciplinary research agenda for light pollution policy. Ecology and Society, 15(4), 13.10.5751/ES-03685-150413[Crossref], [Web of Science ®] [Google Scholar]). Equally important, the framing of environmental problems caused by artificial nighttime lighting via the concept of light pollution has received little critical attention. Understandings of light pollution are reliant on seemingly technical descriptions—light pollution is used to categorize and quantify the adverse effects of artificial nighttime illumination. But such a categorization carries an implicit normative judgment, and should not be accepted without critical reflection. The two main reasons street lights stop working are: Report multiple lights out in multiple locations. This proposed solution to the light travel time problem has some similarities to some of the other solutions. Since the light is miraculously brought to the earth on Day Four, some may see a parallel to the light created in transit theory. However, the large difference is that with this new proposal, the light from distant objects actually left the distant objects that we see; in the light created in transit theory, the light that we see from very distant objects never was emitted by those objects. Some may see that this new proposal is similar to cdk, but there are at least two distinctions. First cdk follows a mathematically described decay; this new solution hypothesizes that light getting here was more of the stretching of space that commenced abruptly and ended abruptly. A second difference is that cdk relies upon physical mechanisms whereas this new proposal relies upon God’s miraculous intervention. One may see an even stronger parallel in this proposal to the white hole cosmology in that the white hole cosmology could provide the physical mechanism for the stretching to get starlight to earth. However, I wish to emphasize that I do not require a physical mechanism for this proposal. Hartnett, J. 2003. A new cosmology: Solution to the starlight travel time problem. TJ 17, no. 2:98–102. If the faulty street light is considered to be dangerous, we will respond to the complaint within two hours to make the unit safe. 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. 5. Criticisms can be found as early as 1662, when a London pastor stated ‘We ought not to turn day into night, nor night into day … without some very special and urgent occasion’ (Ekirch, 2005 Ekirch, R. A. (2005). At day’s close: Night in times past. New York, NY: W. W. Norton & Company Inc. [Google Scholar], p. 74). This was due to the disruption of the perceived natural (Christian) order that such lighting may cause. However, most criticisms are found in the nineteenth century onward, and specifically around times of transition between technologies. Early objections were often esthetic, however moral objections can also be found (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]). There are documented criticisms of artificial nighttime lighting in astronomy-related literature as early as 1866 (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]). Already in the 1880s, Alexander Pelham Tottler—generally regarded as the originator of the scientific study of lighting—identified issues with street lighting that predict modern debates. For example, he argued that too much light is wasted, and that glare causes safety concerns (Bowers, 1998 Bowers, B. (1998). Lengthening the day: A history of lighting technology. Oxford: Oxford University Press. [Google Scholar]). Naturalists and artists expressed ambiguity (at best) towards artificial light as early as the 1920s (Nye, 1990 Nye, D. E. (1990). Electrifying America: Social meanings of a new technology, 1880–1940. Cambridge: MIT Press. [Google Scholar]), and by this time there were already some calls for lighting engineers to reduce urban brightness (Isenstadt, 2014 Isenstadt, S. (2014). Good night.
