Explores the open savannahs of Africa, particularly the mammals that inhabit them and the trees that border the grasslands. Shows how the different animals interact with each other and the non-living elements of their habitat to maintain a healthy balance. Also investigates the threat from an increasing human population for homes, food, other resources, and the resultant threat to the survival of many animal groups. Looks at international breeding programs around the world, which were established to protect these animals and enable them to reproduce in captivity, so their gene pool is preserved. Accessibility options on the DVD are: (1) expanded description, (2) English subtitles in a black box.
