Talk:Light pollution

To-do list

Here'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

Acording 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 any unwanted, inappropriate, or excessive artificial [[Visible spectrum|lighting]]. [...] In a descriptive sense, the term ''light pollution'' refers to the effects of any poorly implemented lighting 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).
