lopburi3 9,909 Posted November 23, 2020 Share Posted November 23, 2020 The AQI is in the red zone here in Bangkok and only a heavy shower this morning makes it breathable. Prior to rain you could not see sun and sky totally orange. As it also was yesterday. 1 Link to post Share on other sites

SomchaiCNX 524 Posted November 23, 2020 Share Posted November 23, 2020 Lost two people dear to me in the last 3 months due to long cancer. Keep your statistics and get to work on it (fixing the pollution problems) instead. The last person was gone in less than two months. 1 1 Link to post Share on other sites
