But I also know that unless we act boldly now, that future is at risk. The Earthshot Prize is about turning the tide, about proving to our children that we are willing to fight for their tomorrow.”Prince William – who launched his £50million initiative in 2020 – landed in Rio on Monday to mark the fifth year of his Earthshot Prize awards.
