Because of the current air pollution crisis, the school has air purifiers in every room, as young children’s health is especially vulnerable to air pollution. This image is part of a story I recently shot for @natgeo. Please visit my profile @paleyphoto for a link to the story. #climatechange #airpollution #mongolia #ulaanbaatar」4月30日 9時06分
