China's pollution problem has gotten so bad that some folks are willing to pay good money to breathe fresh air. Or at least to draw attention to the crisis. Last month, Chinese artist Liang Kieng auctioned off a single jar of clean air bottled in the mountains of France -- it sold to collectors for $860.
But that's not the only instance of Chinese locals trying to get their hands on unpolluted oxygen. In another recent public awareness campaign, residents of the city of Zhenghou collected money to buy 40 bags and 2,000 cans of air sourced from Laojun Mountain's She Shen Ya cliff, which they collectively inhaled in 20 minutes.
