CORRECTS DATE - Smoke and pollution hangs over in Mexico City's iconic Reforma Avenue and Chapultepec Castle, Tuesday, May 14, 2019. Mexico City has declared a pollution emergency over smoke from brushfires that has cast a pall over the city of 9 million. The measure is not accompanied by the usual driving restrictions because this time the pollution isn't coming from cars. The city's pollution alerts are usually triggered by high ozone levels.
