Giving a speech at the heads of state and government session on the final day of the forum, William said: “Rising sea temperatures, plastic pollution and overfishing are putting pressure on these fragile ecosystems and on the people and communities who depend most upon them.
“What once seemed an abundant resource is diminishing before our eyes.“
We all stand to be impacted. And we are all responsible for change – both negative and positive. But there remains time to turn this tide.”
Speaking to an auditorium of 1,800 people, the prince added: “Watching human activity reduce beautiful sea forests to barren deserts at the base of our oceans is simply heartbreaking.

“For many, it is an urgent wake up call to just what is going on in our oceans. But it can no longer be a matter of ‘out of sight, out of mind’.“Halfway through this decisive decade, I call on all of you to think big in your actions.“Let us act together with urgency and optimism while we still have the chance.
“For the future of our planet, for the future generations, we must listen to the words of Sir David Attenborough: ‘If we save the sea, we save our world’.”
William was recorded in conversation with Sir David at the Royal Festival Hall in May, with the veteran broadcaster saying he hopes his new film Ocean, released on Sunday, will galvanise society into action “before we destroy this great treasure.”
In their meeting, the future king chatted with his natural history hero about their shared optimism for future discoveries in the planet’s seas, despite the threats they face.
With a shared passion for protecting the natural world, the prince and the veteran broadcaster have supported each other in their missions to tackle some of the biggest environmental challenges the planet faces.
In his Monaco speech, William said Sir David’s film “makes the most compelling argument for immediate action I have ever seen”.
A Kensington Palace spokesman said: “There should be no doubt that this speech is The Prince of Wales calling for action to save our oceans now. The world is watching.
“This is him using his platform to call for more to be done sooner rather than later.”
As he arrived at the forum, a journalist shouted to the Prince asking whether he was excited to go to Brazil, to which William replied: “Yes”.
William also met finalists, winners and partners of the Earthshot Prize – a global environmental award of which he is founder and president.Kensington Palace said the finalists and winners had showcased “innovative solutions that have the potential to reverse the damage caused to the oceans and that can preserve it for future generations”.
William met Sam Teicher from Coral Vita, a 2021 winner, which works to restore coral reefs by growing coral on land to replant in oceans and Jennifer Koepke from WildAid, a 2023 winner, which scales marine enforcement to end illegal fishing and strengthen ocean conservation.
