Light Pollution: Losing the Dark

Tim Brothers will be joining us from DarkSky Massachusetts.
Founded in 1988, DarkSky International, formerly known as the
International Dark-Sky Association, is dedicated to protecting the
night skies for present and future generations. Its main focus is the
control of light pollution– the inappropriate use of artificial light at
night – which harms our planet and robs us of the opportunity to
experience the wonder of a natural night sky. Today, the organization
is the recognized authority for night sky protection and has taken the
lead in identifying and publicizing the negative impacts of artificial
light at night on human health and safety, wildlife and climate change.
