Prince William makes first official visit

Britain's Prince William on Thursday made his first official visit to the United Arab Emirates, where the future monarch highlighted his passionate work around wildlife conservation and climate change.

The prince delivered an urgent warning on those issues before an audience at the World's Fair in Dubai, known as Expo 2020. He spoke at an event to showcase The Earthshot Prize, a global award the prince founded to highlight and scale solutions to repair the planet.

The Duke of Cambridge's visit coincided with the U.K.'s national day at Expo 2020. He visited the U.K. pavilion and toured the $7 billion grounds of the Expo site, as well as the United Arab Emirates' falcon-shaped pavilion. The one-day visit by the Duke of Cambridge marked a significant milestone in relations between the United Kingdom and the UAE.
