Blue Planet II

Blue Planet II follows the animals that live in the world's oceans, while David Attenborough guides viewers through their lives. The series moves from warm coral reefs and green kelp forests to dark deep water, open seas, and rocky coasts. Each episode shows animals hunting, mating, raising young, and surviving danger. The tone is calm and full of wonder, but it can become tense and sad.

The clearest audience-visible social message is that human activity is damaging the ocean. The first, third, fourth, and seventh episodes connect ocean change to warming water, plastic, industrial pollution, ship noise, and other modern habits. The final episode shows albatross chicks being fed plastic, pollutants reaching dolphins through their milk, and noise blocking animal calls before saying that people must protect the sea. This message is clear and repeated, but it stays broad and environmental, with the show centered on nature and human responsibility.
