The war in Ukraine has upended the lives of millions of people. It's also disrupted the lives of an untold number of animals, both pets and zoo animals. An upcoming episode of Nature on PBS, "Saving the Animals of Ukraine," documents how war-torn Ukrainians are reclaiming humanity by rescuing animals. John Yang speaks with director Anton Ptushkin about the film. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders
