In 2016 as much as 99% of the continental U.S. had some form of light pollution. In fact, almost 80% of North America could no longer see the Milky Way because of light-polluted skies.
The irony here lies in how artificial light is the culprit behind this problem. The lighting technology supposed to boost visibility is hiding the nighttime skies.
However, there’s more to light-polluted skies than just obscuring our views of the galaxy. It also affects our health and even disrupts wildlife and the ecosystem.
That’s why it’s important to learn more about this type of pollution, and what you can do to reduce your contribution. Many of the light pollution solutions are quite simple and doable at home with landscape lighting.
