Globe-at-NightTitle: The Dark Costs of Light Pollution

Description: Much of what we think of as light pollution is the notion that it only matters to astronomers and it doesn’t harm anyone else. The reality is though that because light pollution is often times overlooked, it is a very real problem with consequences ranging from links to cancer in humans all the way to disruptions of the patterns of species. The costs of light pollution go beyond the electricity bill and it is something that can be harmful to ourselves and our environment without us ever noticing the long term effects of blurring out the night sky.


Sponsors: This episode of “365 Days of Astronomy” is brought to you by the National Optical Astronomy Observatory on behalf of Globe at Night. NOAO is the national center for ground-based nighttime astronomy in the United States and is operated by the Association of Universities for Research in Astronomy under cooperative agreement with the National Science Foundation. Globe at Night has been using crowd-sourced observations to track the spread of light pollution since 2006. This year, the project is expanding so that you can collect data every month of the year. If you can find Orion or another one of the bright constellations being used in the program, you can add your data to this ever growing citizen-science effort. For more information, go to

Narrator: When we last left our dark crusader her long time mentor had left for other light hearted endeavors and L.E.D. was darkened. Deep in the light polluted lair of L.E.D. there is something sinister afoot.

L.E.D.: Tungstman! We are losing the battle to illuminate the night sky and keep light bulbs inefficient! What ever shall we do to beat that pesky dark night and her citizen science campaign, Globe at night?!

Tungstman: How will we ever? The Globe at Night campaign has over 11,000 observations with only four months from this year alone! This year with an observing campaign each month that anyone can participate in with the next campaign being from May 19-28, it will be impossible to stop the dark night crusader!

L.E.D.: I’ve got it! Why not use light pollution to wreak environmental havoc on the world! Our pollution will go unnoticed until it is too late, we will be a driving force in the environmental disruption of specie’s mating and migration patterns and we will cause adverse human health effects!

Tungstman: That’s right! Species have ingrained in them a natural day and night cycle and the introduction of light pollution disrupts these natural cycles. By inhibiting certain hormones like melatonin with excessive light pollution we will be able to wreak havoc on the natural cycles of species worldwide!

Narrator.: As L.E.D. and Tungstman diabolically plan, Donna the dark night crusader considers her future fighting back the threat of light pollution with the help of C.F.L.

Donna: Gosh, without the help of Peyton it is going to get increasingly more difficult to fight L.E.D. and Tungstman. Thankfully I have the help of CFL to reduce energy costs and I have the support from the participants of Globe at Night to fight light pollution.

C.F.L. : Donna, I think we have a problem. Look at what the news caster is reporting.

Narrator.: In recent news, researchers have recognized the dangers of light pollution on human health and wildlife and not just astronomical research. It has been found that light pollution can increase the rates of cancers and insomnia in humans and a survey done by the United States fish and wildlife surface has estimated 100 million birds die every year from the adverse effects of light pollution.

C.F.L.: Gosh Donna, I thought light pollution only effected astronomers ability to see at night. I did not know that light pollution has hidden costs like increased cancer rates and insomnia in humans and is responsible for disruption in species migration, hunting, and mating patterns.

Donna.: Wow! This is serious we need to confront Tungstman and L.E.D

Narrator: Both C.F.L. and the dark crusader hop in their dark mobile and head to L.E.D.’s brightly lit lair.

Donna.: It sure is brightly lit for being an evil lair C.F.L.

L.E.D.: So you two have caught onto my plan to disrupt biological processes with excessively bright light pollution, sky glow, and light trespass. It is too late now, you cannot stop me!

CFL.: But you’re wrong! It is possible to turn out light pollution. All over the world people are turning out their unnecessary lights, shielding outdoor lights, and reducing the amount of skyglow, and reducing light intensity both indoors and outdoors.

L.E.D.: Darn it C.F.L! I should have turned you off when I had the chance!

Donna.: CFL is right! An example of an area recognizing the harmful effects of light pollution are the coastal communities of Florida where light pollution was harming baby sea turtles migration from where they hatch on the beach to the ocean where they will live their lives. The community saw that the sea turtles were instead following the light of the city onto roads where they would starve, be hit by cars, or be eaten by predators instead of following the moon to the ocean. These communities have since mandated laws to reduce light pollution and have made it necesarry for homes to draw their curtains at night.

L.E.D.: Darn it! You two have beaten me this time, but I won’t burn out just yet!

CFL: Donna how will we ever beat every aspect of light pollution with so many individual cases of harm being done?

Donna: Light pollution is not something that I can tackle alone, but it is something that every person should be conscious of and take measures within their own lives to reduce the risks of harm to themselves, or the risks to other species in their area.

C.F.L.: That’s right! A lot of the light that we use to light up the night and brighten our homes is unnecessary and we can do without it. According to the International Dark Sky Association an estimated third of all light in the U.S. is wasted in some form costing $2 billion per year. Not only will reducing light pollution help species across the globe, but it will also help reduce our energy bill.
