Introducing Africa...

The savannas of east Africa have more animals than any other grassland area. Rainfall in grasslands is seasonal, and the animals sometimes travel great distances to find grass. Many different savanna animals will gather at rivers and other bodies of water to drink. Plant-eating animals of the savannas migrate by the thousands through the grasslands feeding on the grass while meat-eating mammals--such as cheetahs, hyenas, and lions--roam the savannas in search of prey. Since the rich soils of grasslands are ideal for farming, people have converted many such areas to farmland. Because of this fact, many grassland animals have become endangered due to the loss of their habitat. People have also overhunted numerous grassland animals.
