Our night sky is rapidly disappearing. At our current rate of dumping excess light into the world, a child born today who could see 250 stars right now from their nearby night sky will only be able to see 100 stars from that same spot on their 18th birthday.
Light pollution does far more than ruin stargazing experiences — it has a devastating affect on the environment. Driven primarily by unchecked urbanization, light pollution disrupts firefly mating rituals, lengthens pollen season and makes navigation more difficult for diverse species ranging from monarch butterflies to Atlantic salmon. It isn't good for human health, either. Too much artificial light has been linked to an increased risk of depression while electronic devices can negatively impact our sleep.
