How about appropriate amounts of lighting where it is needed and using logical installations of fixtures that don't waste light by sending it into the sky.
"Lamps do emit the majority of their light in a downward direction, but the majority of that light simply reflects back upward."This is an empirical question, and hinges, of course, on what the quantification of "majority" turns out to be. Even if current lights emit some decent percentage of their light downward, I'm going to guess that a solution which directs the light more efficiently is possible and that the impact it might have on light pollution would be non-negligible.

Seen this a couple of times in flight. Glad I have a picture to show instead of trying to describe it.

Another incorrect generalization. Sure there are bad areas, like any major city.

I'm surprised by the large gentlemen population in the upper right of that picture.

Whenever I come to Chicago I always try to get a night time flight just to see the city lights.

At last month’s SEO Chicago Meetup, one of the attendees asked me if there was a book that he could read that would be a good primer to SEO that would allow him to learn the basics.<a class="user" href="http://www.marketwithartemis.com">http://www.marketwithartemis.com</a>
