Bob Blair (“Same questions,” Letters, Sept. 3) asks: “Since when is light coming from personal residences pollution?”
It is pollution when there are so many porch lights that I can no longer see all the stars.
When I first moved to Nipomo many years ago, I could see the Milky Way with the naked eye.
I have three neighbors who have mercury vapor lights.
They are blinding. I was told when moving here they were not allowed by the illumination code.
When they knocked down the huge eucalyptus forest up the hill, many homes were built, and it seems everyone leaves their porch lights on. Some are blinding.
Blinding light, Bob, is pollution.
All of those lights combined so that I can no longer see the heavens is pollution.
