80 percent of humanity live under a night sky that is not really dark anymore. Because our artificial lighting turns night into night almost everywhere. But that has consequences - for our health and many animals.

Right now, in the dark season, our cities and towns are brightly lit by artificial light. The short time of daylight makes that necessary. But at the same time this lighting covers the natural day-night rhythm. The effects of global light pollution and the magnitude of the scattered light have been shown by numerous studies. But what can be done about it?
