We’re forgetting what darkness feels like

The loss of darkness in cities is having a profound impact on our well-being and the environment. A growing number of cities worldwide are implementing regulations to limit light pollution, but the effects of this shift are still being studied. For instance, the city of Tucson, Arizona, has set a goal to reduce light pollution by 75% by 2025. The benefits of darkness include improved sleep quality, reduced stress levels, and a decrease in the spread of invasive species. However, some cities are struggling to implement these regulations due to pushback from residents and businesses.
