A New York Times editorial stated: "Scientists are only now studying how perpetual twilight affects the lives of birds and other animals, but there is no doubt that a clear, starry night has become a diminishing human pleasure."

"America's public spaces and commercial centers are purposely lit all night: rationalized as a weapon in the "war on crime", but showing, really, a rigid child-like fear of darkness," writes John Laumer at TreeHugger.com.

The Times adds: "Environmentalists, most notably the Arizona-based International Dark-Sky Association, have begun pushing for ways to preserve as much of the night sky as possible. The organization also helps promote dark parks where visitors can observe a starry night, if not like Galileo's, at least like those still visible a few decades ago."

Here are the goals of the International Dark-Sky Association:

1. Stop the adverse effects of light pollution, including:

- Energy waste, and the air and water pollution caused by energy waste

- Harm to human health

- Harm to nocturnal wildlife and ecosystems

- Reduced safety and security

- Reduced visibility at night

- Poor nighttime ambience; and

2. Raise awareness about light pollution, its adverse effects, and its solutions; and

3. Educate about the values of quality outdoor lighting.

In case you're wondering, here's why the sky is dark at night.
