From his commitment to wildlife conservation to his ongoing efforts to combat climate change, it’s easy to see why Prince William launched the Earthshot Prize—an annual award that celebrates the most innovative solutions to environmental challenges.

It's hard to believe it's been nearly 15 years since Prince William married Kate Middleton, but the couple will be celebrating their 14th wedding anniversary on April 29. On Tuesday Kensington Palace announced that the Prince and Princess of Wales will be taking a trip to the Scottish Isles of Mull and Iona next week—and their visit will follow in King Charles and Queen Camilla's footsteps.
