New global warming shock ad features polar bears falling to their deaths

Plane Stupid's cinema ad.  Yeah, I'm pretty sure there's a double entendre there.

From their website:

We have a problem. We're flying too much, and it's changing the earth's climate. Aviation is the fastest growing cause of climate change. But instead of doing anything about it, the Government is planning more flights and larger airports. Like you, we're worried about climate change.
Like you, we don't think the Government can be trusted to do what needs to be done.
It's OK though: we've got a plan.
