NASA | Zebra Crossing

The video explores the second longest zebra migration on Earth, where up to 500 zebras travel a 360-mile round trip annually between the Okavango Delta and salt pans. The migration is driven by environmental cues such as rainfall and vegetation growth. Historically, fences blocked this migration, but since their removal, zebras have resumed their journey. Researchers use GPS tracking and NASA satellite data to study and predict zebra movements, aiding conservation efforts.

What is the significance of the colors red and green in the animation of the zebra migration?
