The “Earth Day Eve 2021” show will be hosted by travel expert Jessica Nabongo and also feature nonmusical appearances by ethologist/conservationist Dr. Jane Goodall, carnivore ecologist Dr. Rae Wynn Grant, environmental reporter Lillygol Sedaghat and biologist Dr. Lucy Hawkes. Part of the program will also be dedicated to marine photographer Brian Skerry offering glimpses of Cameron’s new show. “For over 133 years, National Geographic has strived to inspire people to care more deeply for the planet,” said National Geographic chairman Gary Knell. “Our Earth Day Eve event — virtual and accessible to everyone — will showcase environmentally passionate artists from around the world together with some of National Geographic’s most extraordinary Explorers.
