Its members are universities, public administrations, representatives of manifacturing industries and so on. It produced a specific standard UNI 10819 to (very theoretically) protect the sky from light pollution and some lectures to defend it against the hordes of people that recognized how that standard LEGALIZED light pollution rather than reduce it, but if every one agree I can try to translate their thoughts. To point out how scientists can vary their opinions about this topic it could be useful to summarize prof Zichichi article on catholic magazine "Famiglia Cristiana" and the remarks of prof Maffei, an italian astronomer who pionereed infrared photografic surveys to Zichichi's article. Again, I can traslate. As a final suggestion based on my own experience in Italy I have to remark that the "dispute" about light pollution depends on the strong relationship that links light and energy industries, universities, politicians. Light and energy industries are trying to increase profits and do not accept any regulamentation, universities have to defend their own business and do not like that someone else discovers and applies cheaper and environmental safe lighting rules, politicians fear to lose a powerful argument to gain votes, summarized as "daylight intensity lighting for safety against crime". But I have to remark that only 7 1/2 italian regions on 20, 40% of land and 30% of population have to bear "industrial" lighting rules: in 2007 Liguria, Friuli Venezia Giulia and half of Trentino Alto Adige rejected UNI standards to adopt "zero lighting above lamps" rules. How can exist a "dispute" about light pollution when the majority of a nation says that night skies have to be protected ? --195.210.65.30 (talk) 08:30, 12 December 2007 (UTC)

To-do list
editHere's a list of possible things that the article might benefit from, in no particular order:
1. Remove the liberal bias from the article. Oh wait, you wouldn't have an article without that...
- Reality has a liberal bias. Not necessarily for things that only affect relations between humans (whether kookoo anarchists should let legal heroin stores open in front of schools or not, is Hamas evil..) but definitely for environmental things. The conservative track record is very bad on that. And don't say liberal is tree hugging people that want no wood to be used ever and think the tree's spirit speaks to them, the average liberal's nothing like that.
Feel welcome to edit the list, of course. Izogi 23:55, 10 Jun 2005 (UTC)

Light pollution definition
editAcording to Darksky international "What is light pollution?" "Light pollution is the human-made alteration of outdoor light levels from those occurring naturally." -> https://darksky.org/
I was on the boad of Dark Sky when this was changes. The reason is that old definition was biased by the industry and was incoherent of other definitions of pollution. Like the pollutants on the "1979 convention on long -range transboundary air pollution", where clearly, is included the light pollution. As is explained by the Legal comision of the UN: https://legal.un.org/ilc/reports/2015/english/chp5.pdf.
‘Air pollution’ means the introduction by human activities, directly or indirectly, of substances or energy into the atmosphere resulting in deleterious effects on human life and health and the Earth’s natural environment.
This was even explicitly said on other documents: https://legal.un.org/ilc/reports/2018/english/a_73_10_advance.pdf
All this is expresed on more detail on : Bará, Salvador, Carmen Bao-Varela, and Fabio Falchi. "Light pollution and the concentration of anthropogenic photons in the terrestrial atmosphere." Atmospheric Pollution Research 13.9 (2022): 101541.

- Your change to the lead was:
− '''Light pollution''' is the presence of anyunwanted,inappropriate,orexcessivetheeffectsofanypoorlyimplementedlighting sources, during the day or night.+ '''Light pollution''' is the presence of any artificial [[Visible spectrum|lighting]]. [...] In a descriptive sense, the term ''light pollution'' refers to lighting sources, during the day or night.- The sources you're referring to here don't seem to support your suggested definition of all artificial light being light pollution. --Belbury (talk) 17:26, 29 September 2024 (UTC)
- On this review paper you can see how light levels https://www.mdpi.com/2071-1050/11/22/6400 https://www.frontiersin.org/journals/ecology-and-evolution/articles/10.3389/fevo.2021.767177/full at all scales are been impacted. You are right that should not be "any artificial light", should be "any artificial light at night" and some reflected light during day (light reflected by some solar panels for example).
