Light Pollution

Light pollution is simply lighting that is unnecessary, inefficient, overly bright, and not shielded or targeted. It is estimated that 30% of outdoor lighting in the U.S. is wasted as light pollution, costing 3.3 billion dollars each year. Light pollution degrades skies for optical astronomy, interferes with wildlife, and effects human health.

The great thing about light pollution is that the problem is non-persistent. Once we decide to make a change, our effect is immediate. Start by changing your lighting at home, then move on to educating your neighbors and community. Many cities and even some states have enacted lighting ordinances to protect the night sky. By working together we can bring back the night- there is no reason not to- when the solution is easy!
