Light pollution (excessive light during night time) is a form of pollution that distresses many people, especially in modern cities. What are the causes of light pollution, and what solutions can you suggest for governments and businesses to take?
As more of us live in cities, the question of
light
pollution is becoming increasingly topical and important to address. There seem to be three main causes, and also
two key solutions which we could take to lessen the problem. The main cause is almost certainly the use of lighting for advertising in public spaces. For example, if we look at cities such
as Tokyo or Moscow, almost all available surfaces are fitted with some form of light
, often for announcements or commercial use. This
huge expansion in illuminated advertising is partly a result of competitive pressures, and also
due to
the power of such
advertising, with flashing lights
, video and pictures. A secondary cause is the large number or
street lamps and security Correct your spelling

used in cities, which are intended to reduce accidents and crime by removing shadow areas at night. Finally
, high levels of night-time traffic also
produce light
pollution, as drivers use headlamps which shine into windows and gardens after dark. Turning to possible remedies, it might be tempting for governments to ban or regulate electric advertising billboards, but in many cases (for example
in New York or London) these signs are now a local symbol. It would also

protection for private homes, involving better insulation against outside light
after dark. This
would allow residents
to rest in their homes without being disturbed by the lights
in the streets outside. Additionally
, a voluntary ‘dark day’ once per week, supported by business advertisers, in which all commercial lighting is reduced, would allow residents
to experience a more natural level of darkness without jeopardizing their safety. In summary, advertising and public lighting are the main factors behind this
problem. Better light
insulation, and occasional voluntary reductions in commercial lighting, would greatly help the residents
to live more in peace with a brightly illuminated environmentSubmitted by shuh035 on
