Greenpeace has desecrated a sacred archaeological site in Peru in recent days as part of an AGW-related protest. The result of their renewable-energy-advocating sign unfurling can be seen in the red dotted line here:
1000's of years ago people decided, as part of their religious observations, to make a picture of a hummingbird, and took the time to walk only in very precise lines, so that the images -- formed from lighter coloured clay being brought to the surface by the trampling -- could be preserved and viewed by the gods.
