Beijing City University students make air quality documentary

A few ambitious undergraduate students from Beijing City University filmed a documentary on air quality in Beijing, particularly examining the issue of PM 2.5 measurement and reporting. They interviewed me when I was in Beijing in March. The reason why I speak in English during the interview as opposed to in Chinese is because of the relatively sensitive nature of the questions they planned to ask me.  As a Chinese-American, I consider myself American first and foremost and wanted that to come across. Depending on how they edited the video, I was worried that something I said may have been taken out of context, so it was important for me to not appear as a Chinese, but rather as an outside expert.
