NOW IS THE NEED FOR DARKNESS...

Increasingly, the lovely vision of what we knew as night, is being obstructed by heavily illuminated urban areas. And if the obliteration of celestial lights for the brightly lit city dwellers was not enough, the man-made devastation meted to the avian population stands to be accounted for and analyzed. Factually, for millions of birds that criss-cross the globe, changes made by humans to landscape and flora has resulted in nothing less than a tragic aerial catastrophe. It is reported that about 97 million birds are killed annually by nocturnal and daytime collisions with brightly lit towers and sky-scrapers. Of those who are massacred by the towers are many that are already in the ‘endangered list’. In Toronto, for example, about 940,000 high rise buildings ‘kill’ about 9.4 million birds by ‘bird strikes’ annually. It is reasoned that during day time, birds fly directly into the buildings having glass panes, unable to perceive the images as reflections. During the night, the natural cues that help their aerial navigation (the lights coming from the moon & stars, as also Earth’s geomagnetic fields), get disrupted due to the light from brightly illuminated buildings.
