An in-depth examination by Earth.Org highlights the growing concern of light pollution caused by artificial lights at night, which negatively affects both humans and wildlife. The increasing prevalence of bright city lights obscures the night sky, disorienting nocturnal species and disrupting natural cycles, including plant growth and pollination. Research utilizing the Bortle scale reveals that the brightness of night skies is doubling every eight years, prompting observatories to relocate or invest in mitigation technologies. Light pollution also contributes to air quality degradation, stressing the interconnectedness of environmental issues. Solutions include adopting responsible outdoor lighting practices and following principles set by organizations like DarkSky International. As communities like Flagstaff, Arizona, demonstrate, concerted efforts to curb light pollution can reclaim dark skies, restore natural ecosystems, and yield significant energy savings, ultimately benefiting both the planet and public health.
