For three days on a row, Mexico City has been going through an “unusual” situation in regards to the environment, caused by “airborne particles that are the product of fires.” The lack of a specific protocol for this phenomenon prevented the declaration of a contingency; the Environmental Commission of the Megalopolis only recommended to close doors and windows, as well as avoid carrying out activities outside.

On Saturday, the city was a ghostly vision, caused by the haze covering it and accompanied by a burning smell. According to official numbers, between Friday and Saturday, there were 23 fires in forest and urban areas in the capital; as well as 30 fires in the State of Mexico, including a fireworks workshop in Tultepec and a fire inside a plastic factory in Atizapán.

Pollution in the city is nothing new, it has been a constant struggle during the last three decades. Even when the presence of airborne particles during this season is unusual, couldn't this contingency be prevented?

The millions who inhabit the megalopolis were exposed to PM2.5 particles for over 48 hours, which have a similar structure to aerosols, therefore, they enter the lungs and diminish the levels of oxygenation and in children, it stops the development of the respiratory system.

This situation made weaknesses in the regulations to declare contingencies evident, as authorities lack protocols to act in the presence of airborne particles; an “environmental alert” was issued on Sunday. Yesterday, Mexico City's government recognized that it has to establish new criteria to issue an environmental alert for the 2.5 particles.

In the face of pollution, no matter the cause behind it, society can no longer rely on weather, wind or rain, to solve a problem caused by humans. Authorities should emphasize prevention measures and social awareness strategies and not only focus on reactive actions.

The megalopolis has been able to control but not decrease pollution levels with the help of neighboring governments, environmental groups, experts, business owners, and society but it is clear that a lot more work is needed.

This weekend it was obvious that there are protocols that should be updated. There is no time to waste, it can become a life or death situation.
