The Disappearance of Our Night Sky

Posted in

Light pollution, a byproduct of humanity’s 200-year journey into increased artificial lighting, is disrupting the natural day-night cycle that has governed life on Earth for billions of years. This excess light, primarily from urban areas, not only wastes resources—costing the U.S. economy an estimated $3.3 billion annually and emitting 21 million tons of CO2—but also negatively impacts wildlife, ecosystems, and human health. The International Dark-Sky Association highlights that much of this light does not enhance safety and can lead to increased risks of sleep disorders and various chronic health issues in people. Furthermore, artificial lighting disrupts animal behaviors, particularly for migrating birds and insects, affecting their navigation and survival. The loss of a dark night sky deprives future generations of a celestial heritage that has inspired cultural and scientific pursuits. Efforts are underway to conserve these dark skies and the benefits they provide, urging a collective recognition of their importance.
