39-year-old Kate Middleton and Prince William continue to frequently appear after returning from summer vacation. Last week, the Duchess of Cambridge visited University College London, and today she and her husband took part in an educational event at the Royal Botanic Gardens, Kew.

The event was joined by London Mayor Sadiq Khan, TV host Steve Backhall and two-time Olympic rowing champion Helen Glover. Together, they met with children from the Heathland School and encouraged them to come up with their bold ideas to save the planet.

Kate Middleton and Prince William are slated for another big release this week. The couple are planning to attend the Earthshot Prize ceremony itself, which will be held at the Alexandrinsky Palace in London. It will award five winners who have proposed the best solutions to major environmental problems.
