According to the United Nations website, air pollution represents a high environmental health risk in industrialized and developing countries.

Air pollution is also the cause of premature mortality and 4.2 million of deads around the world.

In Mexico, pollution is part of our everyday lives; therefore, people living in Monterrey or Mexico State are usually affected by small particles of 2.5 microns (PM2.5), which lead to cardiovascular and respiratory diseases and cancer. 

I live in Mexico state, specifically in Tlalnepantla, the more polluted zone in Mexico Valley. 

The principal causes of air pollution are industrial processes where combustion occurs and mobile agents such as automobiles.

Are there any monitoring networks?

Air quality monitoring systems are an elemental source in Mexico, not only for conditions but also for information.

With the information, the SEDEMA is responsible for establishing programs that forbid certain vehicles (which emit more O3).

It is essential to highlight that not all cities with monitoring have sufficient and reliable data to examine the evolution of pollutant concentrations.

But Mexico is working on killing the invisible giant that kills 8,000 to 14,000 people annually just in Mexico City. 

The WHO, through several studies, concludes that approximately 90% of people breathe unhealthy air daily.  Air pollution is not decreasing; on the opposite, it is increasing.

But if there is one thing we are sure of is that it is in our hands to stop this; use fewer cars, demand stricter measures from the government for factories and follow the existing programs.
