(Newser) – Tonight is the longest night of the year, and author Paul Bogard makes a plea in the Los Angeles Times: Let it be the start of a push toward darker ones. Light pollution is so prevalent in the US that those in their 30s might be the last generation to know "truly dark nights," he writes. It's not just a problem for poets and painters—the health effects are real, and they're only going to get worse given that our nights keep getting brighter.

"It doesn't have to be this way," he writes. "Light pollution is readily within our ability to solve, using new lighting technologies and shielding existing lights." LED streetlamps can reduce wasted light, and cities also can simply turn off some of their public lights after midnight. Solutions are possible, "but we will never truly address the problem of light pollution until we become aware of the irreplaceable value and beauty of the darkness we are losing." The winter solstice is a good place to start. Read his full column here.

"Light pollution is readily within our ability to solve, using new lighting technologies" You mean like an off switch?

I recently read an interesting article about how before artificial lighting, people would sleep twice per night. Everyone usually went to sleep as soon as darkness fell, then would wake up around Midnight. They would then stay awake for an hour or two, making love, writing poetry, etc.....They called this waking period after "First Sleep" a time of great creativity and reflection

This is only a "problem" in Cities and Urban Sprawl Suburbs. Small towns and rural areas don't really experience any issues with "too much light" at night.
