Here's a brief summary of the content found in this G-rated documentary. Despite that rating, there are several scenes and bits of narration that might be unsettling, suspenseful or even scary for very young kids (although most older ones likely won't have any problem with the material if they're used to seeing scenes of predation and death on similar nature shows on TV).
Those include scenes of a bird of prey attacking penguin chicks, and a seal coming after and snagging one penguin underwater, as well as comments about and footage of adult penguins, chicks and eggs that have perished in the elements (or seem in danger of doing so). Some suspenseful music accompanies some of those scenes. There's talk of mating and a male penguin is seen starting to mount a female one, but no copulation is actually seen.
