Jennifer Baichwal on "Manufactured Landscapes"

Urban sprawl is a staggering problem in China as a result of the on-going Chinese industrial revolution. Photographer Edward Burtynsky traveled to China to document its "Manufactured Landscapes," and film-maker Jennifer Baichwal documented his trip in her film of the same name. Baichwal talks with Steve Paulson about the scale of China's ecological problems and the beauty of Burtynsky's images.
