King Charles III has teamed up with Amazon Prime to produce a documentary, “Finding Harmony: A King’s Vision,” that presents his long-held belief that restoring the balance between the human and natural worlds is essential to combating global warming and other major environmental problems, according to the Associated Press.

The film, available on Amazon from Feb. 6 and narrated by Kate Winslet, explores the king’s concept of “harmony,” an idea he first laid out in his 2010 book “Harmony: A New Way of Looking at Our World,” written with environmentalist Tony Juniper and Ian Skelly, a former BBC presenter.

“I think we need to follow harmony if we are going to ensure that this planet can support so many,” Charles said in a trailer for the film. “It’s unlikely there’s anywhere else.”

The documentary comes 16 years after the book and aims to reach a new audience through a streaming platform with global reach, according to the report. Charles gave his first speech on the environment in February 1970, when he was 21 and a student at Cambridge.

Tony Juniper, the former head of Friends of the Earth in England, Wales and Northern Ireland, who appears in the documentary, told the AP that the king wants people to recognize that humans are as much a part of the natural world as birds and trees — a reality obscured by modern life spent in air-conditioned offices and buying plastic-wrapped food.

“All of that is reversible, all of that fixable,” Juniper said of problems such as global warming, soil erosion, ocean plastics and chemicals building up in food chains. “But it’s going to require more of us to understand that we are not outside nature, we are in it.”

Juniper said Charles is uniquely qualified to deliver the message because he has campaigned on these issues for decades and continues to do so even as other world leaders shun environmental protection.

“If there’s one person in the world who is literally a globally recognized figure, who has authenticity derived from an incredible track record on these subjects, it is King Charles III,” Juniper said.

Emily Shuckburgh, a University of Cambridge climate scientist and director of Cambridge Zero, who also appears in the film, said the documentary offers a hopeful vision. “It feels as though we’re living through difficult times,” Shuckburgh said. “Having something that provides that sense of hope and optimism is really, really important.”

Ed Owens, author of “After Elizabeth: Can the Monarchy Save Itself?” told the AP that the documentary was a deliberate effort to rebrand the monarchy after a difficult two years. He cited Charles’ cancer diagnosis in early 2024, which forced him to pause public duties and raised questions about his health, ongoing tensions with his younger son Prince Harry, and the scandal surrounding his brother Prince Andrew’s links to convicted sex offender Jeffrey Epstein.

“Let us not be in any doubt, that this is a very deliberate attempt to rebrand monarchy after a couple of very difficult years,” Owens said.

The king’s 1990 foundation of Dumfries House in southwestern Scotland serves as a practical laboratory for the harmony philosophy, offering courses in sustainable agriculture, traditional arts and crafts, and health and well-being across its 2,000-acre estate.

One participant, Jennie Regan, 45, is training to be a stonemason after 15 years as a university administrator. She stood behind a carving that will adorn the floor of a wildlife hide, inscribed with the words “Have I not guided you well?” — a reference to the Scottish fairy Ghillie Dhu. “Things need to be sustainable,” Regan said. “Building sites have so much waste.”
