Fredi Divas, a UK-based filmmaker, has worked extensively in the Arctic and Antarctic. He first visited these regions when working on the BBC documentary series Frozen Planet (2011). He returned to many of the same spots in Antarctica almost a decade later, for the 2019 BBC series Seven Worlds, One Planet. Antarctica is his favourite of the two, Divas says. Aside from the breathtaking landscapes, the animals are touchingly friendly because they’ve had little or no interaction with humans and have developed no fear of the species. Here he discusses treasured moments, and his concerns for these delicate ecosystems.
