Brown and white concrete buildings under white sky

South Korea is suffering and will suffer due to High concentration of "FINE DUST". As COVID-19 slowed down everything that aggravates the air pollution, the concentration doesn't go high as often as it used to. But Before the pandemic, we were often faced to the Fine Dusty Fog, which can slowly kill us. Those photos was taken from exact same spot and show really clearly and foggily the gravity of the situation. The Clear one is when the concentration was below 50㎍/m³ and the fogged one was when it hit above 180㎍/m³. Those photos are originals without any retouches to show the world, the earth needs to breath well to provide the cleanest air for all mankind. #HarperCollins
