Four countries, one planet: Biosphere moves without narration through Canada, Bhutan, Papua New Guinea, and Chile, letting aerial footage and ambient sound carry the film instead of a script. A fisherman working the waters off Papua New Guinea, a construction worker in Canada, monks and mountainsides in Bhutan, and coral reefs shot underwater all get equal weight, cut together as a portrait of how differently people live on the same planet. Roughly midway through, the film breaks from present-day footage into a computer-generated sequence called "Global Warming 2114," imagining a future landscape reshaped by climate change before returning to the real locations that inspired it. Directed by Jennifer Athena Galatis and Dominique Müller, with aerial cinematography by Yousef Alghefari and a score composed by Galatis herself, the film was made in cooperation with the European Southern Observatory. There is no host, no interview, no argument beyond the images themselves: the structure is geographic and seasonal rather than narrative, closing on a segment titled "Planet Earth: Our World Today."
