The industrial revolution was a social and economic change that happened between the XVIII and XIX centuries, mostly in Great Britain and later it expanded all throughout Europe. This revolution impacted manufacturing processes by the introduction of the steam engine and mass production in factories.
Although this revolution had a huge impact on the creation of wealth amongst western societies, there was a cost which had to be paid in order to use the steam machine. The most common fuel for this process was coal. When coal burned it would release a lot of energy that boiled water and then with the steam it moved a series of mechanisms that would power up the machine, since coal is fossilized carbon, and after combustion it would release huge amounts of CO2 ( carbon dioxide ) into the air.
The environmental repercussions of coal burning didn’t take long to be noticed, the combination of the smoke from the factories and the fog created heavy thick black clouds called smog that started causing respiratory problems and even led to deaths, whilst contaminated water from machines and factories was dumped into rivers, contaminating the water and provoking diseases such as cholera.
Nowadays we live under heavy health protocols that are enforced onto the factories by the government in order to preserve the environment stability and the health of the citizens, but not only factories are being accounted nowadays for the pollution that is created in big cities, the use of the automobile also plays a major role in the emission of CO2 into the atmosphere.
Mexico City, one of the biggest urban areas in the world and formally a very heavily polluted city, has been taking steps in order to improve the emissions of CO2 and other greenhouse gases into the atmosphere with social programs such as Vehicular verification, Eco-Transport, like Metrobus, and the implementation of the Ecobici, a system of bicycle rentals for transportation around the centre of the city. These programs and more have led to Mexico City being awarded recognition from the C40 group for air quality.
Once a city whose pollution was apparently without solution has now, thanks to the implementation of well designed long term policies, emerged as an aspiring environmental modern city that keeps on working to improve itself day by day.
