Light Pollution Resources

Here come more stars to character the skies,
And they in the estimation of the wise
Are more divine than any bulb or arc,
Because their purpose is to flash and spark,
But not to take away the precious dark.
We need the interruption of the night
To ease attention off when overtight,
To break our logic in too long a flight,
And ask us if our premises are right."
