One of many firsts in Planet Earth is footage of a wild, giant panda cleaning her week-old cub inside a cave. This baby panda—which is 1,000th the size of an adult—is completely dependent on its mother. Panda cubs are so helpless that if the mother giant panda gives birth to twins, she has to choose which she will care for and which she will abandon. She simply will not have the resources to care for both.
Vanessa says that achieving this first-time footage was far from simple. "A Chinese cameraman spent many months trying to get close to that mother and she just tolerated him," she says. "It takes a lot of field craft to be able to get the trust of an animal like that."
