This title is licensed for public performance by the MPLC umbrella license. Trek to the Earth's largest land habitats, where vast open spaces play host to the biggest groups of animals in the world. Following the immense migrations of caribou across the Arctic tundra and wildebeest through the African Savannah, the program details life on Earth's varied plains: dodging predators, mating and raising young, and , in many grassland habitats, the constant search for water.
