Joshua Simel, 18, a member of the Maasai ethnic group, walks with his cattle towards Tanzania in search of grassland to graze his herd on August 16, 2009 in Kisaju, Kenya. As Kenya continues to suffer from a devastating drought, some of which is man made, the Maasai people have been afflicted by a lack of traditional grassland and water for their herds. Some Maasai have been forced to travel with their herds as far as Tanzania and to the outskirts of Nairobi in search of elusive grass. Some parts of Kenya have not witnessed any significant rainfall for two years. (Photo by Spencer Platt/Getty Images)
