"It's not that people aren't expressing these messages already."
The film begins with Chai Jing's experience as a pregnant woman and then a mother of a child born with a benign tumor, which had to be removed. It looks at China's pollution, how it affects health, and what can be done about it.
Greenpeace's Li Yan said Chai's documentary and the public debate it has generated could help the environmental ministry garner the resources it needs to implement a new, tougher environmental protection law that raises penalties for polluters.

The film might prove a boon to other industries.
Sales of air purifiers at the Blue Air store on 3c.tmall.com, an online home electronics shop owned by Internet giant Alibaba, more than doubled the day after the documentary was released.
