With the pandemic and the stay-at-home campaign apparently there was a decrease in human movement and with that the air pollution generated by and for them also decreased, apparently as a result of this here in the region where I am manufacturing these audiovisuals in winter it's been a really definite winter. But again with the increase in human activity that frigid winter went to a cool autumn, then to a spring temperature, and now as I was writing this text the weather was summer. In this episode the beginning of a pandemic winter is mentioned.
