DARK SKY - As we remove darkness from our world do we truly understand the environmental, social and health impacts of our decision?

Can there be any more of a fundamental truth of the natural world than the rhythm of day following night following day? But when was the last time you experienced true darkness? The truth is we live in a world where the lines between day and night have become blurred. The use of electric light to extend our days has become standard practice over the last 60 years, but at what cost? As we remove darkness from our world do we truly understand the environmental, social and health impacts of our decisions?

As part of a series of free salons hosted by Better Hobart, Landon Bannister of the International Dark Sky Association provided a fascinating talk which explored the environmental responsibilities we all have when using light outdoors; looking at the negative impact light can have on the nocturnal environment and asking the question how much light at night do we actually need? Presented here is recording of his talk along with the accompanying slideshow.    

With over 20 years of experience working within the lighting industry, Landon is a passionate advocate for the important role lighting plays in the human experience of the built environment. He is a member of the Illuminating Engineering Society as well as the International Dark- Sky Association and is actively involved in lighting education.

So if you value what it is to gaze upon the cosmos, take some time to catch up on his presentation at Salon #7.
