AFRICA: DAY VERSUS NIGHT

These two images compare Africa during the day and night. Notice how much of the continent is virtually devoid of lights. This is due to a lack of industrial development. Most people in Africa rely on non-electric lighting such as candles or paraffin lamps. Many animals are adapted to complete darkness, except for the light cast by the moon and stars. The introduction of artificial lights of civilization can have a dramatically negative effect on the nocturnal fauna.
