Give me back the night!

Light has colonized our nights. In Switzerland, light emissions rose by 70% between 1994 and 2009. In the lowlands, it is now impossible to see the Milky Way. Long associated with progress, public lighting is being called into question. In 2019, citizens, scientists and politicians are joining forces to demand a right to darkness. What if, behind the militancy for a "right to the night", lay fundamental human needs, such as sleep, self-knowledge, the exploration of the senses, the quest for introspection, transcendence?
