The Wilderness Society have released overlays for Google Earth that show the scale of the destructive logging going on in Tasmania. It's incredible that we allow this to happen in such a beautiful, untouched place. And for a few dollars a ton, we export the resulting woodchips to Japanese paper mills.
This technique will be very useful for campaign groups. Imagine a map of toxic plumes from exhaust stacks on the M5 and Lane Cove road tunnels? It's a very direct, very "look how close to my house that is" way of bringing the message to the people.
