When is the last time you saw a starry sky?
By some estimates, we only see about 15% of the number of stars our ancestors did. Less than 100 years ago most people could still see the Milky Way. Today, however, millions of children across the globe will never experience this magnificent sight because of light pollution. Everyone is familiar with air, water and land pollution. Light pollution, the inappropriate or excessive use of artificial light, is also a real thing. The glow of large cities is visible for tens if not hundreds of miles obscuring the night sky.
Light pollution is a broad term including:
- light clutter
- light trespass
The International Dark-Sky Association’s mission is to preserve and protect the nighttime environment and our heritage of dark skies through environmentally responsible outdoor lighting. Many cities are working with IDA to implement dark sky initiatives to ensure future generations.
It’s not too late. If you have a view of the night sky and milky way, work with your city planners to ensure it stays that way. If you live in a place where the night sky is no longer visible, take a trip to a dark sky destination and experience what you’ve been missing. Many parks are implementing dark sky friendly lighting.
At home you can take some simple steps to help.
- Inspect the lighting around your home for inefficient, poorly installed or unnecessary lighting
- Use dark sky friendly lighting at your home and business
- Spread the word to your friends, family and online social groups
You can fight light pollution and preserve the night sky and we need your help
