For many centuries the nightscape was the moon and stars.  Now we have many sources of artificial light such as street lighting, roadway lighting, stadiums, parking lots, landscaping, residential, buildings pedestrian and bicycling pathways. In this edition we find out why too much light at night is harmful to animals and humans. The new LED lighting that is currently replacing more orange lights is especially harmful and citizens must call for action now before more inappropriate LED lights are installed.Learn how well thought through outside lighting design and well designed types of lamps, that often point the light downwards, can minimize the impacts of lights at night. We point to the International Dark Sky Association as a source of information and campaigns to reduce artificial light at night.Organisations: International Dark Sky Association website                       International Dark Sky Association FacebookOur guests were presenters at the Fenner Conference for the Environment in the Shine Dome, Canberra on April 6th, 2018.
