pack ice is already diminishing every summer and without pack ice I cannot see how the bears would survive. They are not adapted for living on land," he said. 4The bears live almost entirely on floating ice that packs together to create vast expanses separated by small areas of open water that they swim across. They are superbly adapted for survival in the frozen north, eating mainly seals. They range across a huge area of ice controlled.
