The Bangkok Metropolitan Administration (BMA) has ordered 437 schools under its jurisdiction to be closed today as air pollution has hit dangerous levels. Air pollution in Bangkok has been getting worse since this month. On 20 January, unsafe PM2.5 levels which was set by the Thai government were detected in 50 of 52 areas in greater Bangkok. However, since not all schools in Bangkok are closing, many students will still have to breathe bad air as they go to school. While many students are pleased with the option of staying home, parents are wondering if the BMA’s decision is good for their children's education.
