  1. Support the idea but ..... by pauljuno · · Score: 4, Insightful

    As an amateur astronomer I always support these efforts, not so much because they truly add a lot of value as the potential PR they generate. I live in an extremely urban area and can only see planets and the very brightest stars. And the problem is that we tend to generate a lot of light pollution that is a waste. We don't just illuminate the areas that needs it, but throw off a lot of light pollution because our lights are not focused on the needed area. It's like the standard light in your house, you turn it on and it throws light everywhere even though you just needed it to read a book, it's a waste. I'm not a green fanatic, but it just makes economic sense to try and reduce and eliminate waste where it exists .... plus I really miss seeing the Milky Way.

    In my area it's either light pollution or crime. Having been the victim of a couple of car break-ins because we didn't have the outside lights on, I choose light pollution.

    It's either that or armed guards, and electric is cheaper.


    Considering a lot of light pollution is mostly a matter of inefficiency... Since you think it's a choice between light pollution and crime, I have to assume that you think that shooting vast amount of light into the sky somehow feeds the moon god, who in turn stops crime out of gratitude.

    Seriously, a big part of the problem is with street lights that don't point all of there light toward the ground. Sure, a really well lit ground will bounce some light back up, but some lights literally just shine right up into the sky.

    Also, in many cases excessively bright lights are used, which results in pools of blinding brilliance with pools of pitch black between them. In that case, the solution to make people feel safer is not to make the light brighter, but more even (and possibly dimmer) so that you can't hide in the harsh shadows.
