Little Observed But Greatly Affecting

Earthyy Bags that leaves no stone unturned to protect the Mother Earth from pollution problems now focuses on light pollution that affects the environment in no uncertain way. Regrettably enough, light pollution, unlike other forms of environmental pollution usually remains unobserved, thus creating certain types of unusual hazards. If, however, you feel curious about this lesser known form of pollution, I may tell you that light pollution is indicative of excessive, obtrusive and irritating rays of light created by artificial source of illumination that perturbs us oftentimes.

What Causes Light Pollution?

Light pollution can be caused by sundry forms of light and are termed accordingly, as shown below.

• The invasive light falling inside our rooms from outside at night is a kind of light pollution called light trespass. 
• Large industrial and residential complexes create multiple illumination disorder causing light clutter.

Ill Effects of Light Pollution

Apart from causing ecological vulnerability, light pollution affects the quality of life and overall wellbeing of life on earth. Some of the ill effects of light pollution are outlined below.

Environmental: The International Dark-Sky Association (IDA) estimates that excessive nighttime lighting releases well above 12 million tons of CO2, the most harmful greenhouse gas into the atmosphere every year. Also, according to 2010 study by the National Oceanic and Atmospheric Association, photo pollution increases air pollution by suppressing a naturally occurring radical that cleans the air at night.
Energy Waste: Wasted light gives rise to energy waste. A 2007 IDA study estimated that 30% of all light emitted by public outdoor light fixtures is wasted, which amounts to 22 Terawatt Hours (TWh)/year of wasted electrical energy. This is equivalent to the following:

Around 3.6 million tons of coal per year

Around 12.9 million barrels of oil per year

The total amount of wasted electrical energy each year is enough to illuminate over 11 million homes.

How To Reduce Light Pollution

Use Reflectors: Instead of installing a row of light sources to illuminate your driveway at night, use reflectors to have the same effect. This will not only reduce your quantum of power consumption, but also put a halt to excessive light pollution. This works best with gated communities or in affluent property holdings where a long driveway leads to the prime edifice.

The same is true when it comes to lighting your landscape or outer porch that does not need high power illumination. A single light source and a few reflectors would serve the purpose equally well.

Use Light Switches: whenever necessary, especially when you are leaving a room or entering it. In fact, there is no sense in keeping the light on in a room that is not occupied by anyone. Maybe it was OK in the olden days when electricity charges were negligible and houses were not built so close to each other.  

Use Flash Synchronized: surveillance camera to guard your property instead of installing high consumption light sources. In such cameras the shutter synchronization is supported by an electrical contact within the shutter mechanism, which closes the circuit at the appropriate moment in the shutter opening process. With electronic digital cameras, the mechanism is provided with programmable electronic timing circuits, which may take input from a mechanical shutter contact. The flash is connected electrically to the camera by a cable with a standardized coaxial PC. Needless to say, this method reduces light pollution to some extent.

Reduce The Volume Of Light: escaping from your home, which in turn will trim down light pollution to a great extent by turning on your exterior light’s motion detectors , as a result of which they will come on only when needed.

Go For Starry Night Lights: because these are committed to fighting light pollution, while restoring our legacy of star-filled sky, thereby limiting pollution greatly.
