On Tuesday, Mexico authorities declared an environmental emergency for metropolitan Mexico City. As smoke from nearby wildfires pushed pollution to levels, the pollution deemed potentially harmful to human health. The city's Environmental Commission of the Megalopolis came under pressure to act after visibility in the city began dropping sharply last week due to ash and smoke in the air.
Dry weather has played a role in a spate of fires around the city. Environmental authorities advised residents to avoid outdoor activities and exercise, remain indoors with windows and doors shut, and for especially sensitive groups, including infants, the elderly and sick, stay at home. The environmental authority also asked residents and businesses to do their part in helping to reduce emissions, such as by using cars less.
