On July 13, 1977, a New York City blackout unveiled the stunning Milky Way, a sight many residents had not seen in years, highlighting the pervasive issue of light pollution. Today, one-third of humanity, including 80% of North Americans, are unable to witness the cosmos due to excessive artificial lighting, which not only obscures star visibility but also detrimentally impacts wildlife. An estimated one billion birds in the U.S. collide with buildings each year because of urban lights, and species such as sea turtles and insects face disorientation and navigation problems. Human health is similarly affected, with links emerging between light pollution and conditions like obesity, depression, and sleep disorders. Addressing this growing crisis may be as simple as turning off unnecessary lights, a solution demonstrated by towns like Crestone, Colorado, which found renewed appreciation for the night sky after their streetlights were dimmed.
