Iain Tait and the crew at Poke in London have come up with a lovely idea to help raise awareness of climate change issues.
They're joining with the WWF to build a massive paper plane and paper boat and sailing/flying them to the British Houses of Parliament.
Every person who signs their petition will have their name on the plane/boat. I imagine they'll be constructed from recycled paper.
