Light Is A Type of Pollution Too

How many of you think of pollution in the sense of vehicles releasing carbon monoxide, nitrogen oxides, and such into the air? I think most of us would agree that car pollution is one of the greatest pollutants globally. But have you ever stopped to think that light can be a polluting factor as well? The team at Kastor Energy has looked into this and we understand there to be three different types of light pollution:

  • Clutter: An abundance of light groups which are poorly designed and create confusion such as billboards.
  • Glare: This comes from high disparity between illuminated and dark areas, for instance having headlights shined directly in a driver’s face for a few seconds
  • Light Trespass: Unwanted light trespassing into property or other areas, for instance neighbor’s flood light shining through bedroom curtains.

Now, these different types of light pollution may sound normal but what if it affects wildlife and our ecosystem?

Some animals affected by light pollution are:

  • Birds
  • Bats
  • Turtles
  • Frogs
  • Snakes
  • Fish

Animals can be affected negatively in such great lengths according to this article by Jessica Toothman, “Sleeping cycles, breeding cycles, migration cycles, feeding cycles — animals follow all the proper patterns of life by taking cues from the sun, the moon, the seasons and other earthly phenomenon. An abundance of light confuses them and makes them act out of accordance with nature. It might not seem like a big deal if a flock of birds migrates a month early, but what if it’s too cold when they get to their destination or the nesting conditions aren’t right? Birds can also become confused when they fly over a bright city — without the stars to guide them, they end up hopelessly lost and often fly until they’re exhausted.”

If that’s not enough to convince you then check out The International Dark Sky Association and see what they have to say on the matter.

It’s important that our cities, towns, and municipalities ensure that all outdoors lighting is produced and installed in a way to minimize the risk of endangering our wildlife.
