We're losing the dark sky and you can already feel the consequences

The night sky is getting brighter by about ten per cent each year — that's the scientific estimate. While new forms of lighting technology can reduce the amount of light pollution, the sheer impact of a global boom in artificial lighting is just too much. It threatens the health of both humans and other animals. Historically, darkness has been seen in a negative social and cultural context, so can we change our attitudes and learn to embrace the dark sky? In other words, see the light about the beauty of darkness!GuestsRuskin Hartley – Executive Director, Dark Sky InternationalDr Paul Bogard – Associate Professor Hamline University (US) and author of The End of Night: Searching for Natural Darkness in an Age of Artificial LightDr Tim Edensor – Cultural Geographer, Manchester Metropolitan University Further informationDarkSky International: Five principles for responsible outdoor lightingNick Dunn/Tim Edensor - Dark Skies: Places, Practises, Communities
