     On July 15th Paul Bogard gave a presentation in the Tattered Cover explaining about light pollution and his new book, “The End of Night: Searching for Natural Darkness in the Age of Artificial Light.” The presentation was very interesting and there were lots of people. He answered questions and I interviewed him.

     Light pollution is overused and unneeded light that affects everything. Too much light at night can affect us by disrupting our sleep, confusing our circadian rhythm, and suppressing a hormone called methadone. Mr. Bogard told us that having more light would not make us safer, but instead it would blind us and cause us not to see the criminal that we intended to see with lights.

       Mr. Bogard told me that the world is losing its natural darkness to artificial light and light pollution. Two thirds of the world is covered in colorful lights. Darker places are getting harder and harder to find because everywhere where people live and find jobs is a very bright place. Eight out of ten children will never experience a truly dark night and see the Milky Way.

     According to Paul Bogard, to reduce light pollution people should understand that most of light is waste. The light that shines in our eyes should be shielded or turned off. Reducing light pollution means saving energy. It is estimated that the US spends 2.2 billion dollars on wasted outdoor light.

     Without light pollution about 3,000 stars in colors of blue, red, orange and yellow are visible to the naked eye in dimension. Some of the best spots for stargazing are remote national parks like Great Basin National Park in Nevada and Death Valley National Park in California.

     “So let us go dark!” Paul Bogard calls because the starry night sky is one of the most amazing sights you will ever see.
