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?
Light pollution is the newly emerging menace that might lead to yet unknown but dire consequences. This phenomenon can be attributed to umpteen causes, and thus, it is imperative to explore possible mechanisms to mitigate it. I will discuss both in further paragraphs.
Excessive and inefficient lighting practices, such as using overly bright, or unnecessary illumination contribute to this predicament. This occurs primarily in urban areas where buildings, streets, and public spaces are lit up excessively. Improperly designed lighting fixtures with inadequate shielding allow light to scatter in all directions leading to skyglow, and brightening the night sky over populated areas. Similarly, the motorists and conspicuously shining billboards are also to be blamed for this as they light up the surroundings, and also send beams heading for the heavens.
However, there are certain remedies available to surmount this challenge. Encouraging the use of well-designed fixtures that direct light downwards and minimize glare can produce astonishing outcomes as only the required areas will be highlighted and the skylines can remain relatively darker. Similarly, incorporating timers, motion sensors, and dimming technologies for outdoor lighting can also go a long way; this will help ensure that lights are only active when necessary and can be adjusted according to ambient luminescence.
Additionally, it is mandatory to promote the use of warm-colored, low-intensity LED lights that are less disruptive to natural darkness and have minimal impact on wildlife. On top of that, persuading motorists and businesses to take initiative voluntarily like using low beams while driving, and limiting the time for using self-lighting advertisement hoardings will aid in mitigating this issue.
In conclusion, although eliminating this troublesome situation might be a far cry, alleviation is possible provided lighting equipment is well-designed and meticulously deployed, besides citizens and organizations acting prudently.
