With this definition and sub-categorization, the use of light pollution as a framework for evaluating artificial nighttime lighting begins to come into focus. The undesired outputs of artificial nighttime lighting—be it any of the four broad types listed above—can then be considered in terms of effects. The consequences of light pollution are far reaching, and supporting research is often still at an early stage. However, the effects can likewise be subdivided into five broad categories: energy usage, ecology, health, safety, and the night sky. The past few decades have seen the first large-scale investigations of energy usage by artificial nighttime lighting, as well as its connection to economic costs and greenhouse gas emissions. The International Dark-Sky Association estimates that 22% of all energy in the USA is used for lighting, and of that around 8% is used for outdoor nighttime lighting (IDA, 2014 IDA. (2014). International Dark-Sky Association. International Dark-Sky Association. Retrieved 15 January, 2015, from https://darksky.org/ [Google Scholar]). Another recent study concluded that this number is closer to 6% (Gallaway, Olsen, & Mitchell, 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]). Such studies often focus not just on the amount of energy used for lighting, but specifically the amount of wasted light. A consistent estimate is that approximately 30% of outdoor lighting in the United States is wasted (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]; Henderson, 2010 Henderson, D. (2010). Valuing the stars: On the economics of light pollution. Environmental Philosophy, 7, 17–26.10.5840/envirophil2010712[Crossref] [Google Scholar]).77. By wasted, we can assume this percentage of lighting is deemed to fall within one (or more) of the categories listed above (skyglow, glare, light trespass, or clutter).View all notes This translates into roughly 73 million megawatt hours of ‘needlessly generated’ electricty, with an estimated annual cost of US$6.9 billion. Elimating this wasted light, in terms of CO2 reduction, is equivalent to removing 9.5 million cars from the road (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]). Similar estimates of wasted light in the European Union have predicted that the direct costs amount to €5.2 billion, or 23.5 billion kg of CO2 annually (Morgan-Taylor, 2014 Morgan-Taylor, M. (2014). Regulating light pollution in Europe: Legal challenges and ways forward. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution and society (pp. 159–176). New York, NY: Taylor & Francis. [Google Scholar]). Outdoor Area Light – An outdoor light, typically on private property, that is maintained by the electric company and leased to the customer. This is America’s elected leader — and he essentially, based on his first public response, ignored what the real problem is. And although the White House has come around to bipartisan proposals to very slightly improve background checks and ban bump stocks, the compromises amount to fairly small changes to America’s weak gun laws. 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, Occasionally, the Check Engine light comes on when nothing is wrong with the car, Mazor says. It could be a temporary problem caused by a change in humidity or other factors. In such cases, the light should go off by itself after a short time. In June 2016, it was estimated that one third of the world’s population could no longer see the Milky Way, including 80% of Americans and 60% of Europeans. Singapore was found to be the most light-polluted country in the world.[32][28] Even more significantly, the word עָשָׂה (‘āśâ; “to do,” “to make”) is used specifically of the creation of the astronomical bodies in Genesis 1:16. The meaning of this verb is broader, semantically speaking, than בָּרָא, and may refer to acts of creative ingenuity by agents other than God. That being said, it is indisputably evident that עָשָׂה is commonly used to refer to the act of fashioning something out of already-existing material (for example, the creation of man in Genesis 1:26; cf. 2:7). Granted, such is not always the intended meaning, even with respect to the astronomical bodies (for example, compare Genesis 1:1 with 2 Kings 19:15; Isaiah 37:16; 66:22; Jeremiah 32:17). However, the use of עָשָׂה in the Day Four creation record apart from any contextual clues to suggest that it must bear the sense of creation out of nothing suggests that there is a distinct possibility that the making of the astronomical bodies was instead a matter of fashioning them from material previously created on Day One. Just as the description of the earth in Genesis 1:2 is of something unfinished that God returned over the next several days to shape and prepare, perhaps the matter that would become the astronomical bodies was created on Day One but was shaped on Day Four, whereupon God brought forth their light to the earth. The problem with the last bulb is this; the dimmer switch itself needs to see a suitable load. i.e. it is happy working into a standard filament bulb. It’s driving all your lights in parallel, so whilst there is one regular bulb in there the dimmer is still happy. At the point you replace that last bulb with an LED lamp, the dimmer now sees only LED electronics as its load. The dimmer will not function properly (due to the way it works, it won’t fire correct) and the result is it sends occasional pulses to the lights in its confusion and you observe the flickering. Hi Santosh, nice article. I have a Redmi 3s where the backlight is not working. I can see the display if I shine a flashlight directly on it. Street light replacement project – We’re investing in a £25 million capital project to update and replace thousands of street lights across the town. Since not everyone is irritated by the same lighting sources, it is common for one person’s light “pollution” to be light that is desirable for another. One example of this is found in advertising, when an advertiser wishes for particular lights to be bright and visible, even though others find them annoying. Other types of light pollution are more certain. For instance, light that accidentally crosses a property boundary and annoys a neighbor is generally wasted and pollutive light.
