Talk show host Ellen DeGeneres nicely sums up why great lighting matters: "In the beginning there was nothing. God said, 'Let there be light!' And there was light. There was still nothing, but you could see it a whole lot better."
In New York, NYC Audubon has started the Lights Out NY program and has fostered agreements with corporations behind major buildings, like the Rockefeller Center and Chrysler Building, to turn their lights off at night during migration season.
