Climate campaigner Greta Thunberg prepares to sail to the US

Swedish teenage climate activist Greta Thunberg will set sail for New York on Wednesday, crossing the Atlantic in a racing yacht with no shower or toilet to join protests in the United States and take part in a United Nations summit. To avoid travelling by air, Thunberg is making her trans-Atlantic trip onboard the 60-ft yacht, the Malizia II, fitted with solar panels and underwater turbines that produce electricity on board, with the aim of making the journey zero-carbon.
