A sanitation team comprising a group of "spacemen" collects garbage at a park in Shijiazhuang, capital city of north China's Hebei province April 14, 2014. It was reportedly a behavioral art show intended to raise public awareness of environmental issues. Performers wore space suit to warn people that if the environment continues to deteriorate, there will come a day when people have to rely on heat-proof, radiation-proof spaces suits and oxygen tanks for existence.
