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?
The primary cause of this, not so new, phenomenon is the light escaping from the
conspicuous street lighting systems installed almost everywhere on main roads,
streets, alleys, and several other locations frequented by public. These do not
only illuminate the areas they are meant for but also the adjoining ones. On
the top of that, due to their defective designing or focusing, a lot of light
tends to escape towards the skies too.
In addition to the above, besides street
lights, the big self illuminated bright billboards used by the authorities and
businesses to highlight their establishments and products are also to blame for
this pollution. These brightly shine throughout the night, lighting up the skylines of cities; thus blurring the skies.
Additionally, with security being a major concern today, every nook and corner
of complexes – that may include parking, office complexes, etc. – are given a
more than required illumination, which leaves the areas flooded with light.
However, this, despite being a difficult to
resolve issue, remedies are available.
It is necessary to redesign the street light equipment, which focus only on the
intended areas instead of dispersing in unwanted direction, especially towards
the skies. Furthermore, businesses also must fulfill their social obligations
by limiting the use of huge illuminated advertising boards and hoardings.
To conclude, illuminating public areas is primary factor that is
contributing to the light pollution. Better designs, and imposing voluntary
restrictions on the hours of use of
advertising and decorative could surely help.
