The extent of light pollution as seen from space: NASA image
We need to see more stars ! ( I don’t mean the cartoon type when a character get hit on the head)
The Bain of just about every night sky observer is the problem of light pollution.
Currently light pollution is growing at the rate of 4% and this figure is rising exponentially as developing nations embrace the use of electric light. Light pollution will get worse. There is a solution! Quality lighting benefits the entire community and erases effects of light pollution.
22% of all energy generated in the U.S. is used for general lighting, with 8% of that used for public outdoor lighting. At this rate we won’t be able distinguish night from day.
Light pollution is also a symptom of another serious problem affecting the entire planet thus increasing the carbon footprint just so we can see pretty light.
I am not saying that lighting in not necessary , what we do need access to better designed lighting fixtures by directing light where it’s needed. We need to encourage responsible energy efficiency not wasting resources through over-illumination.

While general lighting is important there is a cost involved, not only a financial cost. We don’t need to waste precious resources on inefficient and unnecessary lighting.
Although I have not seen a study on the effects of lighting affecting human behavior, but there are cases in the Arctic regions where people can experience “cabin fever” by too much light stimulation on the pineal gland disrupting sleep patterns.
A great worth while site to visit is The International Dark-Sky Association (IDA) You can make a difference ! Click here
As people we have a voice you can make a difference. There are some very good originations that promote responsible lighting. There have been some substantial changes to city lighting ordinances in the U.S. in recent years. We are already losing too much of our night sky, how long will it be before it’s all gone.
