Suffocating fine dust

A member of the Korean Federation for Environmental Movements wear a gas mask during a protest at Gwanghwamun Square in Seoul, Tuesday, to urge the government to reduce the operation of diesel cars to lower fine dust levels. Seoul's dust and fine dust levels were “very bad” on the day. The levels are expected to become lower today, with the last of a cold snap hitting the country with strong winds. / Korea Times photo by Seo Jae-hoon
