The night sky is getting 10% brighter every year due to light pollution, making stargazing harder and affecting wildlife. Eighty percent of people live under light-polluted skies, and the International Dark Sky Places network is trying to preserve natural darkness. This trend impacts stargazers, wildlife, and the environment, highlighting the need for better lighting practices. The Milky Way is becoming harder to see in many areas, and the right to darkness could help preserve the night sky as a habitat.
Key Points
The night sky is getting 10% brighter annually, affecting 80% of the global population under light-polluted skies.
2.5 million acres of unpolluted night sky exist in Oregon's outback, a rare luxury in today's world.
The International Dark Sky Places network designates areas with natural darkness, preserving the night sky as a habitat.
Light pollution primarily comes from street lights, buildings, parking lots, and sports courts left on all night.
The number of satellites in orbit has surpassed 11,000, adding to the light pollution in the night sky.
Why It Matters
If you're a stargazer or wildlife enthusiast, the increasing light pollution is a significant issue. The right to darkness could make a few more stars visible and help preserve natural darkness, but it won't turn every city into the rural Oregon outback. The impact on wildlife and the environment is substantial, making better lighting practices crucial.
