The polar bear is the largest land-dwelling predator in the world. Although they hunt seals and other marine animals in the icy arctic waters, they spend most of their time on top of the ice. As climate warms more and more, the vast expanses of ice that the Polar bear relies on for hunting ground will melt further. This could result in the starvation and possible extinction of the polar bear.
