Mexico City's air pollution crisis is a complex and multifaceted issue that has plagued the city for decades.

Located in a high-altitude basin surrounded by mountains, Mexico City's geography is a significant contributing factor to its poor air quality.

The city's elevation of over 2,200 meters (7,200 feet) results in less atmospheric pressure and reduced oxygen levels, leading to less efficient combustion and higher emissions from vehicles and industries.

Additionally, the city's rapid urbanization and population growth have outpaced infrastructure development and environmental regulations. - https://mexicofocusguide.com/blog/mexico-city-air-quality-issues/?unique_id_ilo8l7gj
