Follow the path of the sun on its annual cycle, from the Equator, across the northern hemisphere and into the South. Witness a world bursting with life, as spring and summer follow the passage of the sun. Revealed in all their glory are the natural rhythms of life - the urge to breed, to feed and to raise young - all driven by the sun, the moon and the seasons, across the world.
