Britain's King Charles III warns the world is 'rapidly going backwards' in curbing climate change and biodiversity in a new Amazon Prime documentaryKing Charles III has warned the world is "rapidly going backwards" in curbing climate change and biodiversity loss, in an Amazon Prime documentary getting a Windsor Castle premiere Wednesday. "It's rapidly going backwards," the king said of the current situation, in the feature-length film "Finding Harmony: A King's Vision". "People don't seem to understand it's not just climate that's the problem it's also biodiversity loss," he continued. The king and his wife Queen Camilla were to attend a Windsor Castle screening of the documentary on Wednesday ahead of its worldwide release on Amazon Prime on February 6. They captured the king feeding his chickens, collecting eggs and walking the grounds, as well as hosting a summit with indigenous leaders in July.
