Surprise. Colorado Springs has once again become the focus of a largely negative national media maelstrom surrounding this article by Michael Booth in the Denver Post, which has made a number of rounds on the internet now. Of course, not all of the information in the article is entirely accurate. For example, the City of Colorado Springs never asked people to bring their mowers to the parks as the article insinuates, though grass will be mowed less often.
That said, there’s no denying that the recession has hit Colorado Springs hard and that the city had to contend with deeper-than-average revenue shortfalls because the general fund is so heavily dependent on sales tax revenue. Aside from widely lamentable cuts to public transportation, recreation, culture and safety, there’s been a disproportionate amount of hand-wringing about dimmed street lights. For those of you dismayed about the darkened streets (approximately one-third of the city streetlights have been turned off in an attempt to save $1.2 million—more info HERE), you may find some of the following information on the matter enlightening:
…in Galileo’s time people assumed that the Milky Way must be some kind of continuous substance. It truly resembled a streak of spilled liquid—our word “galaxy” comes from the Greek for milk—and it was so bright that it cast shadows on the ground (as did Jupiter and Venus). Today, by contrast, most Americans are unable to see the Milky Way in the sky above the place where they live, and those who can see it are sometimes baffled by its name. The stars have not become dimmer; rather, the Earth has become vastly brighter, so that celestial objects are harder to see. Air pollution has made the atmosphere less transparent and more reflective, and high levels of terrestrial illumination have washed out the stars overhead—a phenomenon called “sky glow.”
That’s a quote from an excellent article by David Owen at The New Yorker, and there’s another great piece by Verlyn Klinkenborg with lovely pictures HERE at National Geographic. We hope you’ll read both as you consider how a dimmer night time in Colorado Springs will affect you personally.
Here are a few more quotes for thought from The New Yorker piece:
–Tucson gives individual neighborhoods the right to choose whether they want street lights (and to pay for them if they do). Most of the newer, more affluent residential areas, and a number of commercial blocks, have elected to do without.
–Calgary, Alberta, recently cut its electricity expenditures by more than two million dollars a year, by switching to full-cutoff, reduced-wattage street lights.
–In the early seventies, the public-school system in San Antonio, Texas, began leaving many of its school buildings, parking lots, and other property dark at night and found that the no-lights policy not only reduced energy costs but also dramatically cut vandalism.
–The twenty-four-hour day/night cycle, which is also known as the circadian clock, influences physiological processes in virtually all living things. Pervasive artificial illumination has existed for such a brief period that not even the species that invented it has had time to adapt, biologically or otherwise.
-A few years later, [Richard Stevens, a cancer epidemiologist at the University of Connecticut Health Center, in Farmington] persuaded the authors of the Nurses’ Health Study, one of the largest and most rigorous investigations of women’s medical issues ever undertaken, to add questions about nighttime employment, and the study subsequently revealed a strong association between working the night shift and an increased risk of breast cancer. Eva Schernhammer, of the Harvard Medical School, and Karl Schulmeister, an Austrian physicist, analyzed the work-shift data from the Nurses’ Study several years ago, and wrote, “We hypothesize that the potential primary culprit for this observed association is the lack of melatonin, a cancer-protective agent whose production is severely diminished in people exposed to light at night.”
And from the National Geographic article:
–In the south Atlantic the glow from a single fishing fleet—squid fishermen luring their prey with metal halide lamps—can be seen from space, burning brighter, in fact, than Buenos Aires or Rio de Janeiro.
–Of all the pollutions we face, light pollution is perhaps the most easily remedied. Simple changes in lighting design and installation yield immediate changes in the amount of light spilled into the atmosphere and, often, immediate energy savings.
For even more information about the benefits of dark skies, including studies about street lights and safety, the way light pollution affects wildlife and information about how you can further reduce light pollution WITHOUT getting rid of your safety lighting, visit www.darksky.org.
While none of us look forward to losing services to which we’ve grown accustomed, perhaps our eyes will adjust to the dimmer economic conditions and we will view this and other changes in ways that we couldn’t have foreseen. And perhaps we’ll see more stars, too.
