Royals Prince William Reveals How a 'Shy Black Rhino' Was Behind His Earthshot Prize A-Ha Moment Prince William explains how an awe-inspiring sight led him to "to building a team to deliver the most ambitious environmental prize in history" By Simon Perry Published on September 17, 2021 07:35 AM Share Tweet Pin Email Trending Videos Photo: Erica Wilson Studio Silverback/Courtesy Discovery+ / BBC Innovation takes root in the most unexpected place — just ask Prince William! According to the foreword he wrote for Earthshot: How to Save Our Planet, a trip to Namibia three years ago planted the seeds of the epiphany that led to his groundbreaking Earthshot Prize. On his trip to southwest Africa, he caught a "fleeting glance" of rare black rhino and herds of springbok and oryx among the rich, diverse wildlife. And in the communities he visited, he saw a sense of "optimism and determination" among locals both to conserve local wildlife and to thrive alongside it. But when he came home to the U.K., he witnessed world leaders fighting over climate change proposals, pointing fingers and succumbing to division. The despondency he felt in that moment ran counter to the spirit of hope, innovation and activism he'd seen from his father Prince Charles and grandfather Prince Philip, who endeavored "to be pioneers in the environmental movement" in their time.

Suddenly, he writes, "I went from a 5 a.m. start to catch a fleeting glimpse of a shy black rhino in the north-west corner of Namibia, to building a team to deliver the most ambitious environmental prize in history." William, 39, began work to establish Earthshot, which was also informed by his longtime fascination with U.S. President John F. Kennedy's wildly ambitious 1960s Moonshot space exploration initiative. Earthshot encourages all of us charge forward in the coming decade, working together to find innovative solutions to our global environmental peril. The jacket for the new Earthshot book.
