Greg interviews Khun Weena, founder of the Thailand Clean Air Network and an expert on air pollution in Thailand to discuss the who, the what, the why and the WTF behind Thailand’s annual season of poisonous, toxic air.  She begins by outlining the fundamental problem: more or less unchecked economic growth, not only in Thailand but around Asia as well, especially in gigantic countries such as India and China. Although the problem has been around for a while, public interest has peaked due to the increased spread of information about the problem.
