Prince William recorded a message at Windsor Castle for his Earthshot Prize, thanking Attenborough for his long-term support and saying the broadcaster continues to inspire action for the planet. Sir David is a founding member of the Earthshot council, which helps shortlist and choose winners who receive prize funding.
Australian conservationist Robert Irwin also appears in the video, praising Attenborough for inspiring generations to connect with nature. Irwin additionally revealed this week that William and Kate’s children had picked a name for a joey at his Australia Zoo.
