We are now going to transition into our next week full of Loss of the Night activities! Below are some interesting facts about artificial light and light pollution. Are there any other light facts that you would like to share with our team? Message us to let us know!
- Light pollution was first noticed in London and Paris in 1866 when smoke haze prevented citizens from seeing as many stars as previous years.
- Artificial light can confuse sea turtles when they are trying to lay eggs as they look for the moon’s light over the sea to guide them back from the beaches.
- Increases in artificial light at night can disrupt the circadian rhythm, the body’s natural rhythm for sleeping and other important functions!
- Artificial light can even confuse plants causing them to try and keep their leaves over the winter.
- Artificial light at night can confuse lightning bugs, making it difficult for them to find one another to mate.
- It is estimated that roughly 10 to 30% of energy used for outdoor lighting at night is wasted by bad practices and lights, costing an estimated 1 to 3 billion dollars.
- In North America, 80% of people cannot see the Milky Way Galaxy at night due to light pollution.
- The night sky can be up to 500 times brighter in cities than rural or natural areas.
- Light pollution can be reduced by replacing standard lights with low wattage lights.
- Light pollution can be reduced by shielding lights so that their light shines down, not up.
- Light pollution can be reduced by using curtains and blinds at night to keep indoor light inside.
- Oil fields can be major light polluters. The Bakken oil fields in North Dakota look as bright as Chicago and Minneapolis from space due to gas flares and machinery.
- Light pollution can disrupt the migration of certain species of birds.
- The skyglow of Los Angeles is visible from 200 miles away.
- In lakes, light pollution can contribute to algal blooms by preventing the zooplankton from eating algae, affecting water quality.
