@cbsnews: Thick pollution has once again taken over the air in India’s capital, blanketing the region in smog so dense that the air quality this week became among the worst in the world. With air quality reaching a “hazardous” status early Friday morning, essentially every single one of the 33 million people who live in New Delhi are at-risk of health impacts, prompting hundreds of flight delays, warnings and a pause on outdoor construction. #india #newdelhi #airquality #airpollution #smog #pollution #environmentalhealth
