Thanks to China Digital Times for the link to this rather extraordinary video, posted by someone called daughterofchina, whose producers are using the Internet and Youtube as a means of online environmental activism. It would be nice to know more about who produced it. I searched Yoqoo (which I notice is now calling itself Youku, thank god), Baidu, and Tudou and could not find it on any of these Chinese video sharing sites. It must have been posted there, however, so perhaps it has been deleted?
You can find a collection of Chinese videos of newscasts on the Wuxi polluted tap water issue here.
