Costs of Urban Light Pollution
Highlighted in Citizen Science Effort
A recently launched citizen science
project aims to highlight the environmental, social, and financial impacts of excessive nighttime lighting in cities around the world. The project, called Cities at Night
, enlists people to help identify the cities pictured in thousands of blindingly lit photos taken by astronauts orbiting the earth. Organizers hope that when residents and officials see the bright photos of their cities at night, they will be prompted to cut nighttime light use and energy consumption. Widespread artificial lighting has made light pollution
a growing problem in urban areas by disrupting behavioral patterns of people and wildlife, wasting millions of dollars in energy costs, and adding greenhouse gases to the atmosphere. Some solutions are relatively inexpensive and straightforward, the organizers say, such as using shields to direct light down to street-level, which can allow a city to use lower-wattage streetlights.
