Natural World: Elephants - The Long Walk Home
Thousands upon thousands of elephants struggle through a dust-laden, apocalyptic landscape. Whirlwinds of sand a thousand feet high whip the desiccated moonscape. It is a journey that some will never complete. This is a story of vision, struggle, hope and one man's dream to bring freedom to over a hundred thousand beleaguered African elephants.
