Less than 100 years ago, everyone could look up and see a spectacular starry night sky. Now, millions of children across the globe will never experience the Milky Way where they live. The increased and widespread use of artificial light at night is not only impairing our view of the universe, but it is also adversely affecting our environment, our safety, our energy consumption and our health.
What is Light Pollution?
- Glare – excessive brightness that causes visual discomfort.
- Skyglow – brightening of the night sky over inhabited areas.
- Light trespass – light falling where it is not intended or needed.
- Clutter – bright, confusing and excessive groupings of light sources
