The world in our hands awardWinner: Ice matters by Anna Henly (UK) Anna was on a boat in Svalbard an archipelago midway between mainland Norway and the North Pole when she saw this polar bear at around four in the morning. It was October, and the bear was walking on broken-up ice floes, seemingly tentatively, not quite sure where to trust its weight. She used her fisheye lens to make the enormous animal appear diminutive and create an impression of the top predator on top of the planet, with its ice world breaking up . The symbolism, of course, is that polar bears rely almost entirely on the marine sea ice environment for their survival, and year by year, increasing temperatures are reducing the amount of ice cover and the amount of time available for the bears to hunt marine mammalsPhotograph: Anna Henly/2012 Veolia Environnement Wildlife Photographer of the Year
