Light Pollution - Facts & Statisitcs

Sketchbook annotations of key facts I have unearthed about Light Pollution

Continuing on with my alternative idea of exploring Light Pollution, I researched various internet and book resources for numerous facts relating to the issue. The information that I have uncovered came to a shock to me as I didn't realise how harming the situation can be to humans and society. Primarily, Light Pollution is caused from the excessive, misdirected, or obtrusive artificial light, like street lamps and inner city buildings.

Light pollution mostly occurs in major cities, where bright luminous lights dominate the night time skylines and the level of outdoor light use is off the scale. The main concern to campaigners about this overuse is how the light fills up the night sky and disallows the appearance of several stars to be visible, unlike the suburbs or countryside where thousands can be seen in a pitch-black sky.
Hong Kong - No.1 most light polluted city in the world

Out of all the major cities in the world, Hong Kong produces more light pollution more than any other, which has earned them the nick name "The City Without Stars". The city is known for its thousands of illuminated billboards and signs that inter-cross with the main city areas and home communities. The dramatic use of luminous billboards have created sleeping struggles for some residents due to the brightness of light emitted right outside their window, causing changes in their sleeping patterns.

Overly-used artificial light also has effects on the o-zone layer due to the amount of radiation produced, but the intense light can also cause illness in humans, flora and animals. Such effects include skin disease which can possibly lead to cancer. In certain insect species - whose hives reside near powerful artificial light sources - vast amounts of radiation can affect their breeding patterns. A similar feature is seen in the seasonal cycle of trees when they reside near a light source at night; making green-leaved trunks appear in mid-January.
Fireflies

A particular breed of insect - fireflies - normally emit light from their bodies as a mating call, but regions of fireflies found near luminous billboard posters in Japan have found to have a population decline due to the bright light confusing their breeding patterns. Similar incidents have occurred in other insects that can reflect or emit light as well as animal stocks in farms, but in those cases the meats consumed affected humans' health due to light radiation damaging the food stock.

Badly designed lights is prime cause for light pollution, as many outdoor lamps shine straight up, a 180 degree angle, or a full 360 degree angle, when they should be shining towards the ground. These types also help to reduce glare and spillovers.
Campaign poster research

Afterwards, I discovered examples of campaign posters to my base my campaign for light pollution and documented it in my sketchbook. From what I have gathered, it appears light pollution isn't a well known or popular environmental topic nor are there many campaigns in league with it. 


Now, I intend to use these facts to create a fact video on light pollution as a motion graphic. And although I have limited skills in creating one as such, I hope to carry it out as one of my final of three pieces. The other two will consist of a poster and either fact cards or a tangible 3D piece.
