Science & Human Cost

Loss of the Night Sky

Miami’s intense skyglow has made the Milky Way nearly invisible to residents. This reflects a nationwide and global trend:

• More than 99% of the U.S. population lives under light-polluted skies

• Over 80% of people worldwide cannot see a natural dark sky

This loss deprives schools, students, and amateur astronomers of opportunities for observation, data collection, and scientific engagement. Dark skies are essential for astronomical research, and Miami’s lighting places a barrier between the public and science.

Human Health and Energy Waste

Artificial light at night disrupts circadian rhythms, contributing to sleep disturbances and reduced cognitive performance. Excessive lighting also wastes large amounts of energy, increasing costs and carbon emissions without improving safety.
