Not Em-bare-assed in the Least

So 600 people are standing naked on a glacier...

It's no joke. Greenpeace, the dare-to-be-non-violent-enviro-activist group, sent 600 of their least modest members to team up with artist Spencer Tunick for a group project on a Swiss glacier to raise awareness about global nudity and shrinkage.

Spencer Tunick, renown for his large installations of nudes in urban settings, shot this one on the Aletsch Glacier, which is the largest glacier in the Alps. The Aletsch Glacier is in a steady retreat due to the effects of global warming. Some scientists predict that at this rate, all the Swiss glaciers will be melted by 2080 if left unabated.
