Blue Planet III First Look Trailer | Featuring JADE & Hans Zimmer | BBC Earth (Level 1)

Twenty-five years ago, a television series called Blue Planet showed people the world under the sea. Now, a new series called Blue Planet II continues that journey. It goes even deeper into the ocean. The series says we will discover life that is more amazing, more intelligent, and more valuable than we ever imagined. It will also show the strong connection between people and the ocean. This connection is now more important to understand than ever before. In one part of the series, a voice says, "I hear the sea crying." The words are repeated. This message suggests that the ocean needs our attention and care.
