The authorities and the tourism industry deny the facts and neglect all the negative effects of the poor air quality. We all have a responsibility to spread the facts about air pollution in Thailand, so that tourists know and understand this before they come. Then they avoid booking trips to a country they cannot see because of SMOG and exposing themselves to health risks and lung cancer. It's really a bit strange that the authorities don't understand something so obvious, because they breathe this poison themselves.
