In 1954, a young David Attenborough made his début as the star of a new nature show called “Zoo Quest.” The docuseries, which ran for nearly a decade on the BBC, was a sensation that set Attenborough down the path of his life’s work: exposing viewers to our planet’s most miraculous creatures and landscapes from the comfort of their living rooms. On this episode of Critics at Large, Vinson Cunningham, Naomi Fry, and Alexandra Schwartz trace Attenborough’s filmography from “Zoo Quest” to his program, “Mammals,” a six-part series on BBC America narrated by the now- ninety-eight-year-old presenter. In the seventy years since “Zoo Quest” first aired, the genre it helped create has had to reckon with the effects of the climate crisis—and to figure out how to address such hot-button issues onscreen. By highlighting conservation efforts that have been successful, the best of these programs affirm our continued agency in the planet’s future. “One thing I got from ‘Mammals’ was not pure doom,” Schwartz says. “There are some options here. We have choices to make.” Read, watch, and listen with the critics: “Mammals” (2024) “Zoo Quest” (1954-63) “Are We Changing Planet Earth?” (2006) “The Snow Leopard,” by Peter Matthiessen “My Octopus Teacher” (2020) “Life on Our Planet” (2023) “I Like to Get High at Night and Think About Whales,” by Samantha Irby New episodes drop every Thursday.
