Studies suggest that light pollution around lakes prevents zooplankton, such as Daphnia, from eating surface algae, causing algal blooms that can kill off the lakes’ plants and lower water quality.[55] Light pollution may also affect ecosystems in other ways. For example, lepidopterists and entomologists have documented that nighttime light may interfere with the ability of moths and other nocturnal insects to navigate.[56] Night-blooming flowers that depend on moths for pollination may be affected by night lighting, as there is no replacement pollinator that would not be affected by the artificial light. This can lead to species decline of plants that are unable to reproduce, and change an area’s longterm ecology.[57] Among nocturnal insects, fireflies (Coleoptera: Lampyridae, Phengodidae e Elateridae) are especially interesting study objects for light pollution, once they depend on their own light to reproduce and, consequently, are very sensitive to environmental levels of light.[58][59][60] In 2015 it was shown and quantified for the first time the negative effects of direct illumination on fireflies, in a study that monitored populations over four years.[61] Fireflies are charismatic [62] (which is a rare quality among insects) and are easily spotted by nonexperts, providing thus good flagship species to attract public attention;[61] good investigation models for the effects of light on nocturnal wildlife;[61] and finally, due to their sensibility and rapid response to environmental changes, good bioindicators for artificial night lighting.[63] If the faulty street light is considered to be dangerous, we will respond to the complaint within two hours to make the unit safe. A side note here: I grew up in the Throgs Neck section of the Bronx, and during the 1960s, I could see quite a bit of the night sky from my backyard. But today, the city has gotten brighter. Much brighter. So bright, in fact, that now I can easily read a newspaper at night near my childhood stomping grounds without a flashlight. And the skies at my old Adirondack campsite have gotten noticeably brighter, too. What was once a sea of stars against a pitch-black background now looks more like a shade of charcoal gray. The purpose of this paper is to elucidate light pollution as a normative concept, and focus specifically on its increasing role in shaping, or framing, future regulatory efforts, and decision-making processes. The goal is not to condemn or approve of the use of light pollution from an ethical perspective, nor is it to arrive at definitive answers for the ambiguities inherent in the concept. Rather, I begin by accepting the term as the dominant concept for describing a novel environmental problem, and critically reflect on its ethical significance and potential limitations. While the implications of light pollution are far-reaching, here I will focus specifically on light pollution as it relates to urban nighttime lighting. Such an analysis can be seen as an example of an issue discussed within this journal by Elliott (2009 Elliott, K. (2009). The ethical significance of language in the environmental sciences: Case studies from pollution research. Ethics, Place & Environment, 12, 157–173.10.1080/13668790902863382[Taylor & Francis Online] [Google Scholar]), namely the ethical significance of language and terminology choices for framing environmental policy decisions and debates. While Elliott discusses very different types of pollution, the themes highlighted are quite relevant for an examination of light pollution. Elliott—who draws from a more pragmatic branch of environmental ethics that I adopt here—describes the usefulness of practical ethics for policy discussions. Philosophers can help to create and define the moral space within which policy decisions will be made, and so can contribute to upstream policy decisions. Elliot (2009 Elliott, K. (2009). The ethical significance of language in the environmental sciences: Case studies from pollution research. Ethics, Place & Environment, 12, 157–173.10.1080/13668790902863382[Taylor & Francis Online] [Google Scholar], p. 170) explains that, The lights that we own have a code (such as ‘ABCD123’) on the side of the column which is used to identify the light. The code is similar to a house postcode and tells us where the light is located when faults are reported. Light pollution is the adding-of/added light itself, in analogy to added sound, carbon dioxide, etc. Adverse consequences are multiple; some of them may not be known yet. Scientific definitions thus include the following: Some astronomers do not accept inflationary models and have proposed other possible solutions to the horizon problem. These include: scenarios in which the gravitational constant varies with time,5 the ‘ekpyrotic model’ which involves a cyclic universe,6 scenarios in which light takes ‘shortcuts’ through extra (hypothetical) dimensions,7 ‘null-singularity’ models,8 and models in which the speed of light was much greater in the past.9,10 (Creationists have also pointed out that a changing speed of light may solve light-travel–time difficulties for biblical creation.11) Lighting is responsible for one-fourth of all electricity consumption worldwide,[citation needed] and case studies have shown that several forms of over-illumination constitute energy wastage, including non-beneficial upward direction of night-time lighting. In 2007, Terna, the company responsible for managing electricity flow in Italy, reported a saving of 645.2 million kWh in electricity consumption during the daylight savings period from April to October. It attributes this saving to the delayed need for artificial lighting during the evenings. Street light replacement project – We’re investing in a £25 million capital project to update and replace thousands of street lights across the town. If the light is steady, the problem is not an emergency, but you should schedule an appointment as soon as possible. Today’s automotive computers often try to compensate when there’s a problem, so you might not notice deterioration in performance, even though your fuel mileage might be suffering and your vehicle emitting unacceptable levels of hydrocarbons and other pollutants. The blinding effect is caused in large part by reduced contrast due to light scattering in the eye by excessive brightness, or to reflection of light from dark areas in the field of vision, with luminance similar to the background luminance. This kind of glare is a particular instance of disability glare, called veiling glare. (This is not the same as loss of accommodation of night vision which is caused by the direct effect of the light itself on the eye.) My camera does nothing, none of the lights are working. I cant take photos. I tried changing the batteries but it doesn’t help. Anyone who know what to do? Apart from emitting light, the sky also scatters incoming light, primarily from distant stars and the Milky Way, but also the zodiacal light, sunlight that is reflected and backscattered from interplanetary dust particles. Light pollution is artificial light introduced into the natural night, especially where it is not needed or wanted. This unwanted light appears 9. Morgan-Taylor (2014 Morgan-Taylor, M. (2014).

New York, NY: Taylor & Francis. [Google Scholar]) provides a brief analysis of current regulatory efforts in Europe. France is cited as having perhaps the strongest law to date, which requires non-residential buildings to switch off exterior lights and window displays between 1am and 7am. Other examples cited include regions of Italy that have taken a technical approach, prohibited lights above a specific brightness to project above the horizontal.

Energy & Environmental Science, 7, 1806–1809.10.1039/C4EE00566J[Crossref], [Web of Science ®] [Google Scholar]) lists all known regulations and ordinances that are currently in place, as well as their motivations and targets. White hole cosmology is a creationist cosmology invented by creationist Russell Humphreys and put forward in his 1994 book Starlight and Time.[10] The main idea of white hole cosmology is that the world was created inside a black hole and that earth was subjected to intense time dilation so billions of years could have passed outside the field while only a few days would pass inside it.
