Did you know. . .
that 80% of Americans cannot see the Milky Way; 35% of outdoor light is wasted, costing about 3 billion dollars to literally be lost to space; and fireflies, hummingbirds, monarch butterflies, and owls are some of the animals most affected by light pollution? |
|
Artificial light can interrupt natural body rhythms in both humans and animals. An increased amount of light at night can lower melatonin production resulting in sleep deprivation, fatigue, headaches, stress, anxiety and other problems. Studies also show that light pollution can influence animal behaviors like migration patterns, wake-sleep habits, and habitat formation. Because of light pollution, sea turtles and birds guided by moonlight can become confused, lose their way and die.

Light pollution is just one of the many reasons our insects are on the decline. You can read more about it at this link:

Don't Dim the Light of the Stars
On Friday, June 3, 2022, "Don't Dim the Light of the Stars: The Negative Effects of Light Pollution, was presented by Mary Beth Kiczenski, Noted Nighttime Photographer.

Bats and Lighting
Light pollution has been a pretty hot topic for bat research in Europe for some time. Some of the effects appear to be from intensity of light rather than color. Read about light intensity by clicking on the "Intensity of Light" button below.
A study used a before-and-after design where they set up acoustic detectors on the lamp posts for a week prior to replacement and then a week after replacement of the bulbs. Check it out and click on the "Study" button below.
In addition, below is a "Paper" on the effects of light color on bat activity. It mentions how they also measured insect activity, which is a great idea. There are some species like big brown and eastern red bats that will regularly feed on insects (particularly Lepidopteran) near certain streetlights while there are other species like little brown bats who steer clear of these lit-up environments.

Be Aware of Your Outdoor Lighting
Insect populations, a primary source of food for birds and other animals are drawn to artificial lights and instantly killed upon contact.
Safety-related dangers that come with poor visibility at night are caused by glaring lights or bad lighting design, which allows artificial light to shine outward and upward into the sky, where it is wasted instead of focusing light downward, where it does the most good. There are simple measures we can take to make our use of nighttime lighting most effective.
