In reply to the discussion: Greenpeace Irreparably Damage Ancient Nazca Lines [View all]Xithras
(16,191 posts)Look at the ground immediately around the letters. See the footprints? Look at the guy in white walking toward the camera. See the footprints behind him? Now look at the area in the background, where nobody is walking. See how it's more uniform and dark?
NOBODY is allowed to walk around the lines. The Nazca lines are located on a very arid plain, and the lines are protected by a thin limestone crust that leaches out of the ground. Not only will their footprints remain in the area for decades (at a minimum), but those footprints will increase erosion around the lines and ultimately shorten its life.
As many of the articles have pointed out, Peruvian Presidents have asked to visit that very spot, and were turned down because it was too fragile. The entire area is closed to human visitation, and is mostly devoid of wildlife. The lines have only lasted 1500 years because they have been left alone. Walking on them destroys them.
