In this Aug. 2, 2009 photo, a group of giraffes from Africa's most endangered giraffe subspecies walk through scrub brush near Koure, Niger. By all accounts, they should be extinct. Instead, their numbers have quadrupled to 200 since 1996, an unlikely boon experts credit to the concurrence of an impoverished government keen for revenue that has enacted laws to protected them, a conservation program that encourages people to support them, and a rare harmony with humans who have accepted their presence.
