China's Environment Minister has promised to confront an environmental challenge "unprecedented in human history" after an online film exposing his country's pollution crisis went viral with more than 100 million hits in two days.
Chen Jining, a British-educated academic who took office only last Friday, made the pledge following the release of Under the Dome, a feature-length documentary by Chai Jing, a journalist.
Chai's film, which looks at the science and human faces behind China's smog problem, is named after a Stephen King novel in which residents of a small American town are trapped by a mysterious barrier that falls from the sky.
The documentary was released on Saturday and has been watched more than 100 million times on video sharing sites such as Youku, China's YouTube.
"China is now at the tipping point," Fu Jing, another journalist, wrote in the China Daily.
