Disney Nature: Migration' sweeps across the surface of the planet to bring you the mysteries of migration. To find out why and how hundreds of thousands of animals, birds, and insects leave their homes to travel up to thousands of miles before returning, we'll follow several species as they make their miraculous journeys. Along the way, we'll see how both man and nature may conspire against these creatures, making their remarkable treks even more improbable. The DVD includes a special look at a sea turtle conservation project that highlights the delicate balance between humans and nature. A Disney Educational Production.
