When there’s a gathering of world leaders to discuss global issues, you can guess that Greenpeace will have something to say, and do, about it.

Today the G20, the leaders of 20 countries representing 90% of the world’s economic output leaders traveled from the UN in NYC to Pittsburgh for a two-day summit on the current financial crisis.

Well, Greenpeace wants these political heavyweights to focus their attention on issues like the environment, and they showed up to hang out on a bridge in Pittsburgh to get their point across. Catch them in action below and tell us what you think about their most recent stunt – will is prompt action?

Luckily we don’t have to wait for the G20 to get on board, you can stop global warming now.
