WASHINGTON — Light pollution caused by the incessant nighttime glow of electric lights appears to be intensifying, according to research using observations from tens of thousands of people at various locations around the world.
More than 29,000 individual reports were made at more than 19,000 locations worldwide, the researchers said. The "citizen scientists" who provided the data made observations of naked-eye star visibility. "In the last decade, our understanding of the ecological consequences of light has grown dramatically, as has our understanding and modeling of light in the atmosphere," Kyba said.
Light pollution has raised concerns about its ecological effects on people and animals. For instance, research has shown how light pollution threatens fireflies, which possess specialised light-emitting organs and flash to communicate as a part of courtship and reproduction.
