Sea lions bask on rocks on Robinson Crusoe Island, in the Pacific Juan Fernandez Islands, off the coast of Chile, on January 30, 2019. This divers' paradise, some 700 km west of the Chilean coast and with a population of about a thousand inhabitants, has just taken a fundamental step in its conservation – by 2020 it aspires to become free of single-use plastics.
