Chasing Cheetahs (Scientists in the Field)

Since 1900, the number of cheetahs has plummeted from more than 100,000 to fewer than 10,000. At the Cheetah Conservation Fund's (CCF) African headquarters in Namibia, Laurie Marker and her team work to save these stunning creatures from extinction. They've rescued more than 900 cheetahs, most of whom have been returned to the wild.

Sy Montgomery and Nic Bishop join CCF to study the cheetah's ecological, genetic, and behavioral patterns in order to save the fastest animal on land—before it is too late.
