BioClock collaborates in different projects with the Donkerte van de Wadden; this is a program in the Wadden sea area and they pursue more awareness of the importance of darkness and they invite people to experience the unique darkness of the Wadden. Within the Netherlands, this area is roughly the only place it is still really dark at night and you can be impressed by the night sky, you may see the stars and it is a place where night-nature may flourish.
Truly a great project and in line with goals of BioClock. Therefore Anneloes Opperhuizen wrote an article about the importance of darkness for humans.
