Germany plans to dim lights at night to save insects
This reminds me of my local cities new flashy sport arena. 
The sport arena has flood lights to make a UFO landing look good. Cant see anything of the night sky with these on. It is also using a lot of power.<p>I remember star nights walking outside as a kid seeing the Milky way Galaxy full of stars.<p>As for ordinary street lights, the purpose of street lights are for crime prevention, but there is motion sensors. Do we really need to have the lights on with no one on a street?
