Dark Skies Northwest Regional Meeting - December 2nd, 2000

Back to Dark Skies Northwest Home Page

The Time to Stop Light Pollution is NOW!

Seattle's nighttime environment has changed dramatically in recent memory. Thirty years ago it was possible to see the Milky Way from some Seattle neighborhoods. A generation later only a handful of stars are visible. The reason for this change is a proliferation of unshielded lights unnecessarily and uselessly shining light into the night sky, wasting both energy and money. Each year in Seattle several million dollars worth of light needlessly shines into space. Nationally, the estimate is $1.5 billion of wasted light. Across the country and around the world, communities are coming to terms with Light Pollution and are enacting stricter, energy saving, lighting codes. In additon corporations are realizing significant savings from the adoption of shielded and reduced wattage lighting.

In addition to washing out the stars and wasting energy and money, light pollution impacts our lives in other ways. Ubiquitous, unshielded glaring lights actually reduce our ability to see at night. This is especially true for senior citizens, whose eyes are up to three times more sensitive to the adverse effects of glare. Light also trespasses on our property, shines into our bedrooms, and keeps us awake. Recent medical research has even found health risks associated with not having a dark night environment in which to sleep.

On Saturday December 2nd, Dark Skies Northwest, the new Northwest Section of the International Dark Sky Association (IDA), will host an all day meeting devoted to the subject of Light Pollution, its causes, and its solutions.

Who: Sponsored by Dark Skies Northwest; open to the general public.
What: Learn about Light Pollution, responsible lighting design, savings from good lighting, and how to preserve our nighttime environment.
Why: Light Pollution wastes energy, washes out the stars, destroys the character of our natural setting, keeps us awake at night, and may well be a health threat.
University of Washington, Physics/Astronomy Bldg., Room A114
When: December 2nd, 9am to 4:30 pm
Cost: Suggested donation of $5 to $10; no pre-registration required

The meeting will take place in room A114 of the Physics Astronomy/Building on the University of Washington's campus located on the corner of N.E. Pacific and 15th Ave. N.E.
