It’s not a royal decree, but the Prince of Wales wants kids to get excited about improving the world. And he has enlisted BBC Studios Kids & Family’s long-running live-action magazine series Blue Peter to join the quest. 

The show’s team is working with Prince William’s four-year-old  Earthshot Prize, which distributes US$1.3 million annually to innovators looking to activate and scale their ideas for protecting and improving the environment. 

Between now and October 28, British kids ages five to 15 are invited to submit proposed initiatives for addressing climate change, protecting/restoring nature, cleaning the air, reviving the oceans and building a waste-free world through an online portal. They should outline the broad strokes of their idea, as well as explaining how it can be implemented, and what benefits it will yield. A drawing or poster is also a mandatory component for all entries. 

Five winners will be announced during a special episode of Blue Peter that’s slated to air in 2025. They’ll each get a certificate and an exclusive Blue Peter badge for free entry to Blue Peter-branded attractions across the UK, as well as a copy of A Handbook for Dreamers and Thinkers: Solutions to Repair our Planet (with a foreward written by Prince William). 

This episode will also showcase five well-known environmentalists and entertainers. Wildlife TV presenter Steve Backshall and Inka Creswell, a filmmaker and marine biologist, are among these celebs. 

Featuring interviews with celebrities, arts & crafts segments and viewer challenges, Blue Peter has been on air for more than 60 years, making it the longest-running children’s TV show of all time, according to the BBC.
