From Pole to Pole
Series: Planet Earth
This video program examines the planet as a whole and the factors that shaped its history. Sun and fresh water govern the lives of all plants and animals on Earth and define their habitats. Seasons are created by the tilt of the Earth's orbit to the sun. A polar bear must prepare her cubs for the journey across the frozen sea. Habitats discussed in the program include the ocean, the desert and the Arctic.
