What technical design intervention is required to prevent infrastructure lighting from disrupting the natural behavior of nocturnal wildlife?

To prevent infrastructure lighting from disrupting nocturnal wildlife, designers must implement a technical intervention known as spectral filtering, which involves removing short-wavelength blue and violet light from the light source. Nocturnal animals are physiologically sensitive to blue light because it mimics daylight, triggering suppression of melatonin, a hormone that regulates sleep cycles....
