Photo by @paoloverzone | A polar bear walks across the frozen sea in East Greenland. Polar bears live and breed in the northernmost regions of eastern Greenland. Each year, many bears drift with ice southward along the eastern coast. Sea ice melts and disappears quickly as the Arctic warms up twice as fast as the rest of the planet because of global warming. When the sea ice disappears, polar bears have to move onto land, where there are fewer feeding opportunities. Follow @paoloverzone for more images and stories.
