Environmental pollution occurs when pollutants contaminate the natural surroundings. Pollution disturbs the balance of our ecosystems, affect our normal lifestyles and gives rise to human illnesses and global warming.
Deputy Chairman of Cel Fosc. Spain Light Pollution Harms the Environment For a billion years now, multi-cellular life on this Earth has existed with a regular and dependable day-night schedule of illumination levels in the environment.
This regularity is ingrained into the DNA of species up and down our evolutionary tree to our biological advantage.
Natural light entrains or regularizes basic and fundamental biological activities across species from plants to us humans. The effects of light pollution on plants and animals in the environment are numerous and are becoming more known over time.
In general, the most common action is that light pollution alters and interferes with the timing of necessary biological activities. For approximately half of all life, those crepuscular and nocturnal species that begin their daily activities at sundown, our artificial lights at night seriously constrain their lives, exposing them to predators and reducing the time they have to find food, shelter, or mates and reproduce.
To assume that other living organisms on this planet are just going to "adapt" to our newly created lighting schedules for commericial convenience is apathetically ignorant and insane. Unfortunately, it is far, far easier to setup a badly installed light outside than it is to understand the negative effects it casts down-light from it.
All of that bad lighting could be redone by replacing the up-pointing W halogen bulbs with more efficient LED lights and by pointing the LEDs downwards. Overtime, this would cost far less for the taxpayers without causing a single change in the quality of information delivered to the traveler or to compromise their safety.
Such lighting seems especially wasteful as headlights on cars are more than sufficient to light up signs, so the lights are not truly needed at all now. These lights emit high levels of bluish light that not only interferes with our night vision and our own healthbut also with the well-being of animals.
Other types of lighting, such as incandescent or high pressure sodium vapor lamps, produces high levels of reddish or even infrared light. Their spectra interferes with the well-being of many types of plants.
So no living species ever evolved to take advantage of continuous lighting. We should not be surprised that no species truly benefits from it in the long run. A swallowtail butterfly dead in the coils of a compact florescent light bulb.
Just because a light bulb is energy efficient, does not mean that its white spectra is safe for animals. Do you remember yellow? Picture taken by Bryan Bodie and used with permission. However, bad lighting does not stop just at the roads. This page provides an organizational overhead to some of the impacts that light pollution has on different species which have lived on this planet far longer than us "john-come-lately" humans.
The dark blue menu column on the left will also help you navigate these pages as they grow. In the span of a mere one hundred years, our creation of a never-occurring night is having some real effects on the animals that were here before us.
For the same melatonin suppression problems we have with lights at night, creates similar problems in animals. Melatonin is the chronobiotic hormonal regulator of neoplastic cell growth, meaning that it is just the hormonal signal of our biological clockis used for such functions in mammals worldwide.
Biologists describe it as being the most evolutionary conservative hormone that we know of, meaning that it is one of the oldest hormones known across the tree of life that basically signals to genes and organs whether it is daytime or not. Hence light pollution affects animals as well.
A mere glance at the articles in the Light pollution vs. Human Health pages easily confirms this fact as melatonin testing is done over and over on rat species. In fact, it is found in almost all organisms. But melatonin is more than just some ancient hormone buried deep within us and the animals that is being impacted.
Night tells so many animals when to eat, when to sleep, when to hunt, when to migrate or even when to reproduce, it is estimated that half of all life on earth start their daily activities at sundown.
Here is a brief, incomplete accounting of how light pollution harms those living outside our materialistic world.
Our Vanishing Night -- YouTube video by astrogirlwest What happens when all the dark places are gone? Many use the protection of darkness to safely forage and mate. We exist in a balance with our environment, a delicate balance that we are shifting.
In the process we are also losing our connection to the night sky and the universe beyond.
