What does light pollution affect?
A. It affects each and every one of us, not just astronomers. Light pollution is a nuisance, it is wasteful and despoils the night time environment and places an unnecessary strain on the planet’s precious natural resources. Light pollution makes the night sky unduly bright and can prevent stars from being seen. Astronomy from an urban site can be made near impossible by the encroachment of light pollution. The night sky is a precious national and educational resource and is undoubtedly of great special scientific interest.
