Britain’s Prince William took to the waters in Singapore for a morning of dragon boating Monday, ahead of activities for the annual Earthshot Prize awards aimed at promoting solutions for the planet’s environmental threats. Donning a life vest and a black cap, the Prince of Wales sat in a long narrow boat as he paddled with athletes from the British Dragons club on the Kallang river. Working in pairs, William and the other 19 paddlers rowed vigorously to the steady beat of a drummer standing in the bow.
