Polar Bear update

As many of you know, Churchill is known for their polar bears. There are currently polar bears in the area. When we are out in the field someone is always keeping watch, with a rifle ready to scare the bear. The idea is not to shoot the bear, as no one wants to kill a polar bear. Polar bears are wild animals, and the people in Churchill have to be careful that the bears do not begin raiding garbage barrels instead of hunting for their food out on the ice. All of the teachers here would like to see a polar bear, but from a distance!
The other ten teachers with me have been keeping blogs for their students. Click on the Earthwatch Institute: Live from the Field link on the right to find other "Climate Changes at the Arctic's Edge" blogs - tell me something that you learned from their blogs!
