Prince William champions the environment at Queen's Platinum Jubilee
- Queen Elizabeth II is celebrating her Platinum Jubilee
- Her grandson Prince William spoke at the event
- He championed environmental causes
The portion opened with the words of Sir David Attenborough, as images of the world were projected onto the Buckingham Palace with music from Hans Zimmer playing. The crowd then heard archive audio of the Queen speaking about the planet back in 1989.
The Duke of Cambridge, who champions environmental issues, noted that the world had become more fragile during the queen's reign. He noted how the queen had always focused on taking better care of the world and said that it was more important now than ever.
"Together, if we harness the very best of humankind, and restore our planet, we will protect it for our children, for our grandchildren and for future generations to come", the 39-year-old said, as per BBC.
Prince William referred to the other events in the evenings, saying they'd been filled with optimism and joy, something he shared in as well.
While he spoke of the environment, Prince Charles had delivered an incredibly personal speech addressed to his mother - the queen. The Platinum Jubilee concert wasn't attended by the queen, but she did open the show, appearing in a short sequence opposite the Paddington bear.
Earlier in the day, members of the Royal Family were engaged in various events related to the Platinum Jubilee. Prince William and his wife, the Duchess of Cambridge, met the crew and performers before the Cardiff show.
The events have been going on since June 2, and Sunday marks the last set of events to celebrate the queen's reign. The fourth day will focus more on community events where people will be encouraged to have street parties.
Arrangements have been made for a pageant with a carnival procession, that will go up The Mall, and feature celebrities, puppets, and tributes to the seven decades of the queen's rule.
