The Duke of Cambridge surpassed himself when tasked with blue-sky thinking to help save the environment.
When William joined a group of schoolchildren encouraged to think the unthinkable to repair the planet, he came up with getting superheroes to collect the world’s rubbish and carry it into space.
The duke was attending an educational initiative inspired by his Earthshot Prize at Kew Gardens, and was joined by the duchess, the Mayor of London Sadiq Khan, television presenter Steve Backshall and double-Olympic rowing champion Helen Glover.
Each of the famous faces sat at a table with children from The Heathland School, in Hounslow, west London and were encouraged to use objects like drum sticks and an orange, a pile of cardboard and their own brain power to come up with planet-saving solutions.
The tables were also assigned a superhero action figure to inspire them and while Kate had Wonder Woman, William had Ant Man.
Yusuf Rawn, 12, sat with the duke and said about William’s proposal: “One of the ideas was getting all the superheroes together to lift all the rubbish into space.
“We thought it was quite interesting, it would work but sadly we don’t have any super heroes.”
The brainstorming educational initiative was inspired by the duke’s Earthshot Prize which is holding its inaugural awards ceremony at the weekend.
In a statement William called on society to inspire “optimism, confidence and enthusiasm” in the next generation to find solutions to protect the earth.
The duke said: “Education is such an important part of protecting our planet.
“We must inspire in the next generation the optimism, confidence and enthusiasm to chase those solutions and to continue building a more sustainable future.
“We know that young children already identify the climate as one of their biggest worries, and Generation Earthshot aims to educate and encourage them that together we can find the answers.
“Children can be uniquely creative and I can’t wait to see some of the ideas that are shared with us.”
