MONACO – On June 8, 2025, Prince William delivered a compelling speech at the Blue Economy and Finance Forum in Monaco, urging global leaders to act swiftly to protect the world’s oceans. The address, made on the eve of World Oceans Day, underscored his rising stature as an international advocate for environmental causes.
Speaking at the Grimaldi Forum alongside French President Emmanuel Macron, Costa Rican President Rodrigo Chaves Robles, and host Prince Albert of Monaco, the Prince of Wales emphasized the ocean’s critical role. “Healthy oceans are essential to all life on Earth, generating half of the world’s oxygen and providing food for over three billion people,” he said, according to a Royal Family Channel broadcast on June 8, 2025. “Yet, rising sea temperatures, plastic pollution, and overfishing are putting pressure on these fragile ecosystems.”
The forum, a stepping stone to the 2025 UN Ocean Conference, highlighted the global commitment to protect 30% of land and sea by 2030. With only 3% of the ocean currently protected, William stressed the urgency of bold action, noting, “The clock is ticking.”
As King Charles continues cancer treatment, William, 42, has taken on a more prominent role, building on his lifelong passion for conservation. His Earthshot Prize, now in its fifth year, was central to his message. The initiative, set to hold its next awards in Rio de Janeiro, supports innovative solutions to environmental challenges. “I’m an optimist because I see the incredible ideas and technologies harnessing the power of the ocean while protecting its vitality,” he said, per the Royal Family Channel.
William spotlighted Earthshot finalists at the event, including Coral Vita, a 2021 winner that has grown over 20,000 corals off Grand Bahama, and Pristine Seas, a 2021 finalist that has helped establish 29 marine protected areas spanning an area twice the size of India. My Algae, another finalist, has saved 2.54 million wild fish in six months by producing omega-3 from algae, reducing pressure on overfished stocks, according to the same source.
The prince’s speech followed the release of a Kensington Palace film on June 7, 2025, featuring his conversation with Sir David Attenborough, whose upcoming documentary, Ocean with David Attenborough, reinforces the need for immediate action. William echoed Attenborough’s call, stating, “If we save the sea, we save our world.”
With President Donald Trump in office since January 2025, global environmental policies face scrutiny. William’s plea for “ambitious action on a global, national, and local level” serves as a reminder of the shared responsibility to protect marine ecosystems.
