Beatifull video !
If you see your skies being damaged by badly installed lights or lights that are blinding you as you drive, you can call your local Goverment or city hall and make a complaint. In Canada, they have to investigate your complaint. I got many problem lights corrected this way and you can too. Just aim for the bad lights and complain. And remember, turn your lights off if you don' t need them. Act, complain about it and do something locally. It will add up

Beautiful movie! Here in Germany there's a discussion running to enact a law against light pollution. Let's all hope, that the people will learn it :)

Every year thousands of new high-pressure sodium lamps are not properly installed (too much, too bright, and light is directed above horizon line).
