Nudity
People for the Ethical Treatment of Animals (PETA) had a protest for animal rights, "I'd rather go naked than wear fur." which was so effective in reducing the use of fur in fashion that it ended after 30 years, declaring victory. At first there were naked people protesting in front of clothing stores, but changed to ads by famous people. The Femen group demonstrates topless to call attention to a number of feminist issues. The World Naked Bike Rides are done annually in many cities in the world to protest dependence on automobiles and fossil fuels.
