Why Darkness Matters
Wow, so many stars!
Animals
Many animals are busiest at night. Darkness helps them feed, travel, hide from predators and find their way.
Plants
Plants use the change from day to night as a signal for when to grow, flower or rest.
People
As evening gets darker, our body clock gets the signal to slow down and prepare us for a good night's sleep.
The Sky
Too much artificial light can make the night sky glow, hiding stars, planets and the Milky Way from view.
Too much light at night can change the natural patterns that people, plants and animals depend on. That's why darkness matters!
