What is Light Pollution?

Light pollution is artificial light which shines where it is neither wanted, nor needed.

Light pollution can be a problem due to either distant bad lighting (seen as skyglow) or very immediate, local lighting (often causing nuisance to home-owners).

Both cause a range of problems.

Light pollution, caused by bad lighting, has...

...resulted in human fatalities
...severe security implications
...wasted vast amounts of money
...disturbed neighbours
...destroyed wildlife
...caused medical health problems
...a major environmental impact
...hidden the view of the stars.
