Photo by Pete McBride @pedromcbride | Misty Mountains: Fog settling over the Himalaya creates a beautiful landscape, but the scene it mirrors in northern India’s cities is less idyllic. Delhi’s geographic position worsens its smog problem, which is further spread by winds that pick up dust and sulphur dioxide particles and carry them across the country. Those pollutants then become trapped and accumulate over the northern plains. In the winter, smog levels are 40-80% higher when the winds drop off and are unable to blow air pollutants out of the region. Earlier this year, smog in Delhi reached emergency levels, sounding the alarm to address the unchecked development that has led to India claiming 14 of the world’s 15 most polluted cities.
