Seeking San Francisco IDA members for Dark Sky action

I have been asked if I can find a IDA representative to participate in a stakeholder committee associated with the San Francisco Commission on the Environment.
The committee apparently is promoted/requested by Lights Out San Francisco and American Bird Conservancy.

As I am told "The goal of the program is to reduce unnecessary night lighting in the city of San Francisco to reduce the threat of nighttime collisions with buildings for migratory birds, conserve resources, save money, reduce greenhouse gas emissions, and ultimately increase visibility of the night sky."

This is VERY early in the process of forming the stakeholder committee.

If you are interested please contact me.

If you would like to get more involved in Norther California activities please join the Cal-IDA yahoo group go to:

Help IDA raise awareness in the US Congress about the problems and solutions of light pollution by inviting your Representative's Legislative Assistants on Energy, Environment, Science and Health to a briefing on light pollution.

Each year, millions of Americans glance into the sky in the hopes to wish upon a star, or gaze at the wonders of the universe, only to discover their view has been replaced by a yellow haze.  And while the loss of starlight may seem inconsequential, or just a sad reality of our continuing development, did you know there are other critical issues linked to light pollution?
· Light pollution has consequences for human health.
According to the journal Chronobiology International, the breast cancer incidence is approximately 73% higher in communities with higher levels of artificial illumination at night.

Discussion by: Dr. David Blask, Senior Research Scientist and Head of the Laboratory of Chrono-Neuroendocrine Oncology at Bassett Healthcare Institute (NY)

· Light pollution wastes energy.

IDA estimates over $10 billion is wasted annually on unnecessary lighting.
Discussion by: Lee Cooper, Manager of Emerging Technologies at Pacific Gas & Electric (CA)

· Light pollution harms the environment.
Light pollution affects all species from zooplankton to birds to sea turtles.  Hatchling sea turtles, including Loggerhead and Leatherback turtles, find their way to the sea by differentiating between dark, elevated areas, and the bright, flat sea surface; misdirected light confuses this process.
Discussion by: Travis Longcore, Ph.D., Science Director of The Urban Wildlands Group (CA) and co-editor of "Ecological Consequences of Artificial Night Lighting."
There are alternatives!!!  
Please join the International Dark-Sky Association, a 501 c3 nonprofit organization dedicated to preserve and protect the nighttime environment and our heritage of dark skies, along with fellow endorsing organizations as we discuss these consequences associated with improper night lighting. 

 IDA will present a strategy for reducing these adverse effects of light pollution at minimal costs, or even cost savings, by using more sensible outdoor lighting.

    OUR FAR-FLUNG CORRESPONDENTS about light pollution and its effect on astronomy and the environment. Writer describes Galileo Galilei’s 1610 astronomical observations. Today, by contrast, most Americans are unable to see the Milky Way in the sky above the place where they live. The stars have not, of course, become dimmer; rather, the earth has become vastly brighter, so that celestial objects are harder to detect. Air pollution has made the atmosphere less transparent and more reflective, and high levels of terrestrial illumination have washed out the stars overhead—a phenomenon called “sky glow.” 

    In my opinion this is the best "light pollution" story ever published by a popular magazine.
