World Naked Bike Ride participators - just a few moments prior to the official start of the three hour ride. On Saturday 11 June several hundred cyclists rode through London naked to bring attention to issues of car pollution, lack of cycle infrastructure and the failure of governments to give a priority to the safety of cyclists. "To draw attention to oil dependency and the negative and social environmental impacts of a car dominated culture." According to the latest research 9.500 Londoners die every year due to pollutants caused by NO2 and PM 2.5. However, besides the focus on car pollution and cycle safety, the ride was also a celebration of the human body with many of the riders painting their bodies although full nudity was optional.
