Tree Hugger - "[Polar bears] are dependent on the Arctic sea ice for all of their essential behaviors, and as the ice melts and global warming transforms the Arctic, polar bears are starving, drowning, even resorting to cannibalism because they don't have access to their usual food sources," said Kassie Siegel, staff attorney for the Center for Biological Diversity.

Scientists have noticed increasing reports of starving Arctic polar bears attacking and feeding on one another in recent years. In one documented 2004 incident in northern Alaska, a male bear broke into a female's den and killed her.

Walt Meier, a research scientist with the National Snow and Ice Data Center in Boulder, Colorado: "Seven million square kilometers roughly corresponds to an area of the lower 48 United States. So back in the early 1980s, the lower 48 states would be covered in sea ice in the summer. Now we've essentially lost sea ice east of the Mississippi River and even beyond. So that's a significant amount of area."
