Prince William referenced his three young children's futures to mark the halfway mark to his 2030 climate crisis activism pledge. The royal, 43, shared a short film via Instagram on Saturday, October 4, in advance of his upcoming Earthshot Prize gala, which takes place in Rio de Janeiro, Brazil, on November 5. In the video, Prince William sat under the same oak tree near his Windsor home where he initially announced a 10-year climate activism project in 2020. "Now, more than ever, is the time to fix the planet," he urged viewers.
