Stone monkey sculptures are seen wearing face masks in heavy smog at Beijing Zoo in Beijing, China, 19 December 2016. Engulfed in choking smog, some northern Chinese cities limited the number of cars on roads and temporarily shut down factories Monday (19 December 2016) to reduce air pollution during a national "red alert." More than 700 companies stopped production in Beijing and traffic police were restricting drivers by monitoring their license plate numbers, state media reported. Dozens of cities closed schools and took other emergency measures after a "red alert" was issued from Friday night to Wednesday for much of northern China. Authorities in the northern province of Hebei ordered coal and cement plants to temporarily shut down or reduce production. Elsewhere, hospitals prepared teams of doctors to handle an expected surge in cases of pollution-related illnesses.
