FAQs about Air Pollution

2. What are the causes of air pollution?

Environmental pollution generally occurs when certain elements that cause harmful effects accumulate in quantities that nature cannot recycle. In the case of air, from the 1950s, the concentration of pollutants on a global scale reached levels never seen. This period, which has not concluded, some specialists have called “the great acceleration.”

The conclusion of the Second World War turned into an intense demographic growth and a period of welfare. The end of the conflagration brought with it the consumption of all kinds of new products, new materials and new production methods. The cheapening of production opened the doors to mass and consumer society. Since then we have witnessed the expansion of megacities, mass transportation and tens of millions of motor vehicles circulating on streets and highways. All this has caused serious problems such as environmental pollution, acid rain, the deterioration of the ozone layer, the greenhouse effect and pollution or smog that reaches intolerable levels, especially in mega cities, where overcrowding has proliferated, respiratory diseases, allergies and other pathologies.
