Light pollution is any adverse
effect of artificial light, including sky glow, glare,
light trespass, light clutter, decreased visibility at night,
and energy waste.
Light pollution wastes energy,
disrupts global wildlife and ecological balance, and has been linked to negative
consequences in human health.
Mission of the IDA:
The mission of the International
Dark-Sky Association (IDA) is to preserve and protect the nighttime environment and our heritage of dark skies through quality
1. Stop the adverse effects of light pollution, including;

Losing The Dark - a 6 minute
video published on Feb 2
Starry skies are a
vanishing treasure because light pollution is washing away our
view of the cosmos. It not only threatens astronomy, it disrupts
wildlife, and affects human health. The yellow glows over cities
and towns — seen so clearly from space — are testament to the
billions spent in wasted energy from lighting up the sky.
To help raise public awareness of some of the issues pertaining
to light pollution, Loch Ness Productions in collaboration with
the International Dark-Sky Association has created a 6.5-minute
"public service announcement" called Losing the Dark. It
introduces and illustrates some of the issues regarding light
pollution, and suggests three simple actions people can take to
help mitigate it.
Losing the Dark was initially created in fulldome video format
for digital planetarium use. It also has been made as a
conventional flat screen video, for use in classrooms, kiosks,
museum theaters, and advocate multimedia presentations. Classic
planetarium theaters without fulldome capability can show this
version using their traditional video projectors.
