The Prince of Wales began his two-day US visit in dramatic style, crossing the Hudson River with the Manhattan skyline in the background.
William arrived from the UK on a commercial flight and travelled straight to Governors Island to meet students, volunteers and restaurateurs involved in the Billion Oyster Project, a unique initiative to restore oyster beds in New York harbour.
He stood in the bow of the boat with Pete Malinowski, co-founder and executive director of the Billion Oyster Project, as it travelled to the outcrop at the centre of the operation.
During his visit William will promote his Earthshot Prize which aims to celebrate and scale up solutions to “repair” the planet, and announce the 2023 finalists.
Later he will sit down for talks with UN secretary general Antonio Guterres as the 78th session of the UN General Assembly begins.
The first stop for William will be the hatchery centre for the fledgling oysters, and he will tour a group of tanks where the next generation is being nurtured.
He will also meet a group of high school students who are volunteering and learning about the project to restock the oyster population, with larvae relocated to a nursery made from discarded and cleaned oyster shells from 75 New York seafood restaurants.
The shells are housed in metal cages in the East River and it is hoped the molluscs, which cannot be eaten because of water pollution, will form oyster reefs providing three important benefits – filtration, new habitat and protection against storms.
