Why Dark Skies Matter
With urbanization, 80% of humanity can no longer see the Milky Way from their homes. Dark sky reserves are not just sanctuaries for stargazers; they are vital for migratory birds and nocturnal wildlife.
- Observation: Large countries in North America and Oceania dominate due to vast wilderness.
- Fun Fact: While the U.S. holds the record for most individual parks, small nations like Niue are leading in per-capita protection, famously becoming the world's first 'Dark Sky Nation'.
