Today's forecast: overcast with a 100% chance of polar bear. Hope you brought your umbrella!

Plane Stupid, a "network of grassroots groups that take non-violent direct action against aviation expansion," creates an ad in which lifeless polar bears fall form the sky, resulting in gruesome bloody impacts with the world below.

The statement: planes create a crapload of emissions, as many pounds as a fully grown polar bear.

Obviously the members of Plane Stupid have never experienced the horror of Amtrak.
