Negative Effects of Artificial Light

    To raise awareness about an under-recognized environmental issue:
    Light pollution is caused by excessive and misdirected (upwards and sideways) lights. In short, artificial light at night is scientifically proven to affect wildlife (e.g. frogs, turtle hatchlings, migratory birds), human health (e.g. circadian rhythms), and the night sky (obscuring the stars, Milky Way, etc). In naturally lit nights, the stars alone are bright enough to light the ground. Overly bright lights shining at you (glare) impair your night vision of seeing in the shadows where potential criminals hide. All dark-sky advocates ask is that you aim your lights downward when and where you need them. That way, you can save money and energy. It's a win-win situation.
    From a peer-reviewed scientific journal: Nature
    Further info: Scientific American, Wikipedia

    I FUCKING KNEW IT!

    Just like excessive noise pollution, this shit goes largely ignored because the effects are so long-developed no one realizes what's going on.

    I swear to GOD the florescent lights are damaging to your skin. When I had to stand for 8 hours at a convention my hands and face would be BURNING by the end of the day because of those lights. In fact I have visible red spots on my hands.

    Wow that's enlightening education. No pun intended. icon_lol.gif

    It's amazing how when I go camping to the middle of nowhere you can see so much more since our pupils are fully opened versus having to contract a bit with light pollution.

    Seems like a lot of power could be saved if we just used the power of the universe at night.

    I totally agree about this one! I can remember how clear the Milky Way was, when I observed it in a remote mine in Western Australia. Or when I was trekking in the Peruvian wilderness.

    A clear night with a dark sky is amazingly beautiful. The Milky Way is so prominent. You see the ancient light from stars that may no longer exist. You can watch the satellites traverse in the sky in their orbits. During peak meteor events, you can watch meteors streak across the sky, several per minute.Out here in the high desert you can walk the land illuminated by nothing more than star light.

    My town has a dark sky ordinance to preserve the beauty. You can't have lights on the ground pointing up to illuminate a building. New street lights are carefully chosen so that light points only downward. Business signage must be lit from above.

    If your local government does not have such an ordinance, please consider being the person who brings the issue up for consideration.You can find a model ordinance here:

    Future generations will thank you!

    I often visit this small town in Mexico that has not one single light on at night. The stars are AMAZINGLY bright. The sky looks beautiful and surreal. The first time i saw it i was so mesmerized and sad that I didn't know the sky could look so brilliant.

    Not that I disagree with that, but "scientific american" is not a peer reviewed journal.

    I just don't understand all the people who want to move to the country then put up a mercury vapor street light that burns all night long. It drives me nuts. And the new fad is those solar-powered driveway lights. People putting up mansions in the hills line their driveways with hundreds of those things. You can see them for miles.

    But the absolute worse is the damned wind turbines. Each one of those things has a red strobe-light on top that can be seen for 30 miles. And there's thousands of them. They light up the whole desert, where it's supposed to be dark. Even more creepy, they're synchronized for some reason, so they all light up at the same time.

    This was very interesting, I've never really thought about light as being a pollutant. I'm going to share this with my friends. Very cool!

    Artificial light bothers me GREATLY, especially the blue or green leaning light spectrum, like the shitty florescent lights used in cheap grocery stores. Sometimes when exposed to these damn lights for hours (like at expositions) I actually get burns and blisters on my hands!!!!

    On a similar note, another under-represented awareness is that of noise pollution. I feel like only people who are aware of how bad it is plugs their eyes when sirens go by them. Virtually no one plugs their eyes when this happens! NOOOOOOOOOOOOooooo.........

    Thankfully many of the new shopping centers and new streetlights are finally taking this into account and are using new styles of lamps that don't direct the light upwards.

    IIRC there was a Simpsons episode on this way back.

    I don't plug my ears because I don't want to look like a pussy, but I can't fucking stand it when I can hear people partying because their music is way too loud and shit like that.

    Since this topic was bumped up today (3/26), happy Earth Hour, which passed for me. IDK if it actually saves that much energy though. Maybe it's just a symbolic reminder.

    I agree with you serioushat about the circadian rythm. I have trouble myself to get to sleep when my room isn't dark enough.

    I really don't think it's possible to burn under Fluorescent light, if anything there's 'less' in it than sunlight to burn you. visible light is visible light, just different colour temps.

    I get where your coming from here. When I was in school the fluorescent lights would give me migraines after an hour or two of sitting in the classroom. Same thing from going grocery shopping. Had it checked out and the doc basically said my pupils were not adjusting correctly under the lights so too much of it was getting into the iris and causing pain. Had to wear prescription sunglasses just to go to class lol.. it also caused my eyes to itch and burn. Seems to have faded over time though as it doesn't get to me anymore.

    i do remember that the basis of operation of a fluorescent lamp is UV light, the white coating on the tubes gives off the white color and at the same time filters out the UV from the mercury vapor inside. how efficient this UV filtering probably is related to why you feel ¨toxic¨ after some time.

    A few years ago, I had some teenagers staying in my house on the farm. Friends of the family, from the city, helping out with the harvest for some extra cash. One night, I almost literally tripped over one of them, out in the yard in the dark.

    "What is that?"
    "What, I don't see anything..."
    "That. *pointing* What the hell is that?"

    Eighteen-year-old kid had never seen the milky way before in his life. icon_rolleyes.gif
