Every winter the Harbin (China) Ice and Snow Festival assembles 200,000 blocks of ice to make a city. Millions come to see it. “The workers, most recruited from local villages, spend over a month each year cutting 3-foot-thick blocks of ice from the river and transporting them to the festival site, where they are sculpted and stacked by an even larger team of workers. Beginning before dawn and working through the day in temperatures that average -13 degrees Fahrenheit, the workers earn around $35 a day for some of the world’s most backbreaking labor.” – Wired
