Plane Stupid - Polar Bear

A British environmental group has produced a video that shows falling polar bears slamming into the sides of buildings, onto the sidewalk or into the top of a parked car. The group, Plane Stupid, equates the weight of each bear, 400 kilograms, to the amount of greenhouse gases produced by an average European flight for each passenger it carries. Andrew Revkin, a New York Times reporter who covers the environment, has checked the facts.
