Cheetahs, the world's fastest land mammal, were once found throughout Africa and Asia, from the Cape of Good Hope to the Mediterranean and throughout the Arabian Peninsula and the Middle East.
Yet in just 100 years, numbers in the wild have plummeted from more than 100,000 to around 10,000 today.
In Namibia, the Cheetah Conservation Fund is working to save the mammal and its habitat through education, conservation, public policy, science and research.
Russell Beard travels to Namibia in southwest Africa to see how initiatives such as restoring habitats, rehabilitating and releasing injured cheetahs, and dissuading livestock farmers from shooting the big cats could save this species.
