What is light pollution? - DarkSky International
Light pollution is the human-made alteration of outdoor light levels from those occurring naturally. When we over-light, fail to use timers and sensors, or use the wrong color of light, we can negatively affect many parts of our world, including migratory birds, pollinators, sea turtles, and mammals, including humans.
Interactive Light Pollution Map - Academo.org
A map showing how light pollution varies across the world. This interactive map shows the worldwide artificial night sky brightness at zenith (looking straight up) at sea level. The techniques used to calculate this data are important as they quantify night sky pollution levels, allowing us to monitor how the levels vary over time.

2022年1月22日 · The top diagram is an example of bad outdoor lighting; the fixture throws light upwards and sideways. The bottom diagram is an example of good outdoor lighting; the fixture directs light downward, protecting the night sky. Graphic by NPS / Larry Wilson. The primary cause of light pollution is outdoor lights that emit light upwards or sideways.
