Smog Journeys.

Jia Zhangke's short film for Greenpeace East Asia depicts the effects of air pollution in northeast China, a region frequently blanketed in dangerous levels of air pollution. 'Smog Journeys' traces two families from two different backgrounds; one a mining family in Hebei province, and the other a trendy middle class family in Beijing. Both face a similar fate. Air pollution is one of China's most pressing environmental and health issues. Greenpeace calls for a shift from coal to clean renewable energy, as well as short term measures that better safeguard people's health.
