Light Pollution Abatement at the Royal Astronomical Society of Canada

Light pollution makes it harder to see the stars, but it also has long-term negative impacts on human health, heritage, and the environment. The RASC recognizes that natural dark skies are an important ecological and cultural resource, and has a dedicated team who promote awareness of the impacts of artificial light at night and lead efforts in light pollution abatement across Canada.
