Global warming has all sorts of negative effects on the world and its creatures. [29] Tusks were once thought to be used to dig out prey from the seabed, but analyses of abrasion patterns on the tusks indicate they are dragged through the sediment while the upper edge of the snout is used for digging. It has rebounded somewhat since, though the populations of Atlantic and Laptev walruses remain fragmented and at low levels compared with the time before human interference. These ever growing gatherings can be deadly, especially for young calves.
