Once Upon a Time... Planet Earth Season 1 Episode 39
Teenagers, the internationally-recognized characters of the series, will be the heroes of adventures in which they will play an active role. They will be a force for change, faced with situations and problems they need to resolve. The series will be based on facts, yet still primarily entertainment. Through their actions, they directly affect their planet and the resources that must be used responsibly and are not inexhaustible. The series will also help younger audiences to understand that pollution, hunger and water shortages are realities with specific causes – rather than inevitable evils to be dreaded, they are battles to be won with solutions to be found.
