To everyone who is cool enough to be planting a tree because it's the done thing: For every cola bottle you buy we'll plant a tree, for every ton of wood pulp your corporation uses we'll plant another, for every Multi Launch Rocket System we manufacture we'll plant a dozen trees. For every £1.82 litre of petrol you pump we'll reanimate a dinosaur and promise to nuke all future comets of a certain size that might threaten the earth. Get two meal deals from Tim Horton's and we'll plant a tree and create a unicorn from spare genetic materials we found in the lab on an old petri dish.
