National Geographic has a feature article on light pollution, and the social, environmental, and biological effects that the loss of darkness has exacted on humans and non-humans alike. Among the many unforeseen consequences of light pollution: increased incidence of certain types of cancer, birds dying from disorientation in the urban light-jungle, frogs’ and toads’ circadian rhythms.

The highlight of the report, though, is an incredible photo slideshow, which almost tells the story just by itself. Familiar places are transformed into strange, luminous mazes and the wildest corners of the countryside are shown in the glowing penumbra of far off sodium lamps. Another reason I love night photography.
