I had planned a post to review some promising new rechargable flashlights we used on farm, when a story caught my eye on Firefox's home screen. At first I thought it clickbait, until I spotted Atlas Obscura. The word "Darkness" intrigued my roving eye, and I clicked.
My class had just finished reading LeGuin's A Wizard of Earthsea, a fine book for younger readers about a talented young man's journey to wisdom, focusing on his Taoist realization that darkness and light need to exist in balance. It's a contrary approach than that taken in much fantasy literature, where a Manichean division exists: Sauron vs. Aragorn, for instance. Darkness in Tolkien is usually metaphorical and dangerous. It tempts us to power over others, rather than power from within.
But Tolkien rises above moral dualism; he loved the natural world. In his books we get dark skies full of stars that the Elves enjoy. That literal sense of darkness as awe-inspiring and necessary brings us to a lesson from Moffat, Scotland that we might employ in our lives. To a small degree, we have been trying it where we live. This quotation, by "Astrophotographer and dark skies advocate Josh Dury" struck me as particularly wise:
“If you squeeze the whole of human evolution into a single day, artificial lighting has been around for a minute,” says Dury. “Exposure to light at night can have serious health implications.” He adds: “It can particularly affect our body’s hormones, including the production of melatonin, which is responsible for maintaining sleep patterns and nocturnal rhythms.”
Read the piece for inspiration. Moffat succeeded where other communities continue to blot out the sky, at enormous cost to our natural sleep cycles and the stability of our climate. Even low-energy LEDs require power to run, so they are far from carbon-neutral.
Even if we dim our own small lights, not all of us live in places where we can turn down community lighting to see the Milky Way arch over our suddenly tiny heads. We are puny, compared to the panorama overhead.
What can each of us do to bring back some darkness? I don't always succeed every day but:
- Steering clear of all screens for an hour or more before bedtime
- Leaving house lights off in rooms that are empty
- Avoiding the American trend of spotlighting a house to show it off at night
- Replacing interior and exterior lighting that blots out the night with task lighting where possible, and where not?
- Installing security lighting triggered by motion. Always-on means always injected carbon dioxide into our air.
- Considering where all lights point. We replaced large floodlights with equally bright but lower-energy LED floods pointing downward. That way, when we need to check outside during the time when Copperhead snakes roam our yards, we can see them. Once back inside, out go the lights.
Winter remains my favorite season, partly for the lack of hot, humid weather and the orderliness of a winter landscape, but also for the power of the dark sky. It's perfect for stargazing. This year I learned a few new winter constellations that I can, luckily, see where I live. Cassiopeia, Andromeda, and Perseus became nightly companions.
In town, it was Orion. That was about it. During a trip to New York City? Nothing except the Moon. Times Square is magical at night, but I'd not be able to live in a large city again for more than a short while. I'd miss the dark too much.
I hope that in years to come, we'll rediscover how powerfully darkness helps us, as creatures who evolved to benefit from both light and dark.
Next time, the flashlights!
