Inside Story - Choking China

As thick smog envelopes China's northeast, we ask whether the government is acting fast enough to contain the crisis. What will happen to China if the government does not tackle the problem? And what are the consequences for people and their health in the current crisis? Inside Story, with presenter Jane Dutton, is joined by guests: Andrew Leung, an independent China analyst and economist; Huang Wei, a climate and energy campaigner for Greenpeace; and Kurt Straif, the head of monographs at the cancer research unit for the World Health Organisation.
