National Wildlife Federation Naturalist David Mizejewski explores the relationship between sea ice and polar bears. As continued global warming leads to less ice in the arctic the bears have less opportunity to hunt for food. David outlines the direct link that sea ice has to the feeding habits of polar bears and why a warming climate is a danger to the species. With the help of Polar Bears International, NWF scientists learn first hand about the threat to these awesome creatures.
