    ... and I'm not trying to troll or anything, but is there anything humans do that isn't considered some form of pollution?

    While that's a true statement, there is no reason to avoid making an attempt to reduce our impact on the planet while we're here.

    I believe we're already screwed, as unless at least 75% of us (some would say this should be much higher) just disappear tomorrow we're basically going to burn up all the resources before we figure out how to co-exist with them. We have a chance, ozone will stop depleting in the next ~20 years and start making a comeback; it all depends on whether or not we've triggered the next ice age by the time it can recover. I think it's a decent shot but will only hold up until the next limitation we run up against.

    The fact remains that we are so far beyond the Earth's capacity that without a large catastrophe or huge reversals in birth rates our long-term chances of surviving are nil. Something we'll end up taking from the planet will snowball with an effect that makes it uninhabitable. I see cleaning light pollution as one of the things which can make our time here more enjoyable (you know, like breathing clean air as well.)

    While it's all well and good to try and practice conservation, even if all 6 billion of us recycled to our heart's content there wouldn't be a long-term difference seen. To survive this population requires a global paradigm shift which is about as likely as Angelina Jolie showing up at my desk to compliment my creative programming skills.

      The stargazing on Hawaii is even more spectacular. However, the best stargazing I've ever done was from a little island on a tiny atoll several hundred miles west of Hawaii. Since there isn't anything resembling civilization nearby, it was about as black as one could imagine, as it was before moonrise. The night sky is completely chock full of dim lights that we have no hope of seeing when there is any ambient light at all. It really is amazing.

It's difficult to describe the pain of not being able to be outside in the dark and see the stars. It's very abstract, and unless you've been out away from cities for a significant period of time--I think a month, at least--it's difficult to appreciate.

    Same goes for noise pollution. And pollution pollution. When I came to the US, I spent a couple weeks in Riverside, CA. I went into Vernon, an industrial district of LA, with my friend Jon for one day. As we entered the city, I could feel the air entering my lungs, it was so thick. After 8 hours in Vernon, we left, went to dinner, and got to the place we were crashing. Some of the people in the group went out, but I didn't feel well, so I laid down. That night, I slipped into a hallucinatory high fever. Way way way better than TV. Anyway, the fever lasted a week in a half, and the rattling cough lasted 3 months.

    Now, light pollution is less serious than that, but I'm sure it accounts for at least part of my depression living in St Pete. Which is why I'm moving.

  41. That'd help by jgoemat · · Score: 1

    It's not just that simple, but I think light pollution could be better calculated using that and some algorithms. One thing to take into account is elevation, at higher elevations the same amount of light visible from space wouldn't equal the light pollution. With less atmosphere to go through, more light will pass into space so the satellite will record a higher value than the same lights at a lower elevation, while less will actually be reflected back to the ground by the atmosphere so there will be less light pollution. Also let's say you are looking at a normal street lamp. Without a special hood, a lot of the light goes up into the atmosphere at various angles, but not straight up. If the satellite was directly overhead, it would not count all the light pollution produced by these lights.

  46. 'Glare bombs' make it easier for criminals by geekotourist · · Score: 1
    As this article on light pollution from Slashdot's last article on light pollution points out, badly done lighting could be worse than none at all.

    "...the key to visibility, on runways as well as on roads, is contrast...The lighting near the mailboxes was of a type that Crawford calls "criminal-friendly": it was almost painful to look at, and it turned the walkway behind the boxes into an impenetrable void. "The eye adapts to the brightest thing in sight," he said. "When you have glare, the eye adapts to the glare, but then you can't see anything darker."

    Much so-called security lighting is designed with little thought for how eyes--or criminals--operate. Marcus Felson, a professor at the School of Criminal Justice at Rutgers University, has concluded that lighting is effective in preventing crime mainly if it enables people to notice criminal activity as it's taking place, and if it doesn't help criminals to see what they're doing. Bright, unshielded floodlights--one of the most common types of outdoor security lighting in the country--often fail on both counts, as do all-night lights installed on isolated structures or on parts of buildings that can't be observed by passersby (such as back doors). A burglar who is forced to use a flashlight, or whose movement triggers a security light controlled by an infrared motion sensor, is much more likely to be spotted than one whose presence is masked by the blinding glare of a poorly placed metal halide "wall pack."


    i.e. if a passerby's pupils have shrunk to the size of pinholes because of a glaring light, their ability to see their feet, let alone a criminal, will have disappeared for several minutes. The same if they're driving by: they're less likely to see criminals by a house or moving creatures (deer, dogs, running children) by the road. [And then there's how the deer will also be blinded (more than humans for a given glare bomb).]
