Approximately 600 people shoot nude on the Swiss Alps glacier

Photographer Spencer Tunick, who I mentioned earlier about shooting in Mexico, shot a group nude on the Aletsch Glacier, which is also a World Natural Heritage Site. This shooting was done as a campaign to spread awareness of global warming by Greenpeace, an international environmental protection organization. Movies and photos recording the situation are released.

A flock of people lined up on the glacier.

A slope that seems to be quite dangerous if you fall.

If they are gathered in one place, they will not be visible to people.

It looks pretty cold, but the temperature is 10 to 15 degrees Celsius. It doesn't seem to be a level where you can nail with a banana.
