WHEREAS, light pollution can negatively influence natural ecosystems, human health, and energy sustainability; and,
WHEREAS, light pollution can disrupt migration patterns in birds and other animals; and,
WHEREAS, Madison lies along the Mississippi Flyway migratory bird path; and,

WHEREAS, light pollution obscures our ability to observe the night sky and its constellations; and,
WHEREAS, outdoor lighting should be designed to minimize its impact on the environment; and,
WHEREAS, the City of Madison is committed to fostering environmental, economic, and social resilience and created the Madison Sustainability Plan in 2011; and,
