S1, E2: From around three months old, our animal babies can all get around on their own, but that means the impact of their environment and the struggle to find food really begin to hit home. In California, a three-month-old sea otter pup has to learn what is safe to eat in a world enmeshed with humans. In Sri Lanka, a seven-month-old macaque is forced by his mother to toughen up to stay on top. And in Kenya, a five-month-old elephant has a limited window to meet and bond with new families to survive in an increasingly dangerous world. The animal babies are fast growing into their abilities, but every day brings new challenges to their success.
