Summary
   At night, look up at the sky. How many stars do you see? If you live in the country, bright stars will fill the sky. If you live in a city, on the other hand, you might not see any stars. What’ s happening? (26)Bright lights from the city are lighting the sky, blocking the stars. This is light pollution.
   Light can also come into city homes, like an uninvited guest. Sometimes, a visitor to a big city can’t sleep because of the bright, flashing sign outside his or her window. Darkness helps us sleep. (27)Without darkness, we lie awake losing sleep. Losing sleep can lead to serious health problems because our immune systems become weak.
   Nature’ s beings need darkness. It’ s part of the natural 24-hour cycle. Trees and plants that are too close to artificial light grow in strange ways and die quickly. (28)Animals become confused when the normal patterns of light and dark are changed. For example, birds flying to their winter homes can get lost. Also, night animals might think it’ s day when it’ s actually night.
   Finally, (29)using too many lights wastes energy and money. The huge lights for all night parking lots and gas stations are too bright and unnecessary. Every city spends millions of dollars a year to light its thousands of buildings and streets. And much of this lighting is just to make the city look attractive, rather than to provide practical use.
   True, we feel safer in the light. But our eyes are able to see a little in darkness. And we don’t need to light the entire city just to create an attractive night view. (30)We should try to turn the lights down to save the Earth and its creatures from this pollution.
