Las Cruces declares April 2025 as International Dark Sky Week to combat light pollution

Las Cruces has officially declared the week of April 2025 as International Dark Sky Week, a move aimed at raising awareness about the importance of preserving natural night skies. The proclamation, made during the city council meeting on April 7, highlights the aesthetic and ecological value of dark skies, which are increasingly threatened by light pollution.

The council's decision comes in recognition of the significant impact light pollution has on both the environment and human health. With approximately 80% of the global population living under light-polluted skies, the proclamation emphasizes the need for responsible lighting practices to mitigate this issue. It is estimated that light pollution costs the United States around $3 billion annually in wasted energy.

Local resident and emeritus professor John Holtzman, who chairs the New Mexico chapter of Dark Sky International, spoke passionately about the need to protect this natural resource. He noted that many people have never seen the Milky Way, underscoring the privilege of living in an area where dark skies are still accessible. Holtzman pointed out that a natural night sky not only inspires curiosity and wonder but also supports local ecosystems, including species that rely on darkness for their survival.

The council encourages residents to adopt lighting practices that minimize light pollution, such as using shielded fixtures and lower color temperature lights. These measures not only preserve the night sky but can also enhance safety by reducing glare. Holtzman stressed that responsible lighting is achievable and beneficial, advocating for community education and potential strengthening of local ordinances to combat the growing issue of light pollution.

As Las Cruces embraces International Dark Sky Week, the city aims to foster a greater appreciation for its night skies and promote sustainable practices that benefit both the community and the environment. The council's proclamation serves as a call to action for residents to engage in this important initiative, ensuring that future generations can enjoy the beauty and wonder of a star-filled sky.
