Wildest Africa: Zambesi River of Life (2011)

For 2000 miles, the mighty Zambezi flows from the Zambian highlands trough Angola, Botwsana and Zimbabwe to Mocambique, to end in the Indian Ocean. Its immense water volume has a massive impact on wildlife in its huge flood areas and trough erosion reshapes its own bed, most spectacularly at the Victoria falls, the world's greatest waterfall.
