Urban jungle : Dia de contingencia en la cuidad de Mexico

During a contingency day in Mexico, car or motorised vehicles are not supposed to be so many ! But as it has been possible to listen, motorized vehicles were there! That could seem very strange to cut trees during a pollution alert in Mexico. One can have the feeling that nature will disappear with such kind of local habits! Actually people must be reminded that 40 years ago, before cars invaded the south of Mexico city, the place was occupied by trees, birds and cows! Xochimilco ecological zone is not too far from this place! What I found, listening the city this day of may, was the feeling that motorized noises will not be in place for centuries. Broken tree branch noises, birds that we can listened from time to time are a clear message than resilience is not an abstract concept. Colibri are still leaving in this noisy and polluted city. Obviously human pressure is a high threat for many species but as we can listen here, trees are still growing (it was really needed to cut tree branchs before the earthquake in September 2017 to protect people). Few animals are able to survive our destructive way of life. But few is not nothing. Here, birds, dogs, humans struggle to be heard. We are not better positioned than other species. Maybe, this is a recording of a specie that probable should disappear... the humans. Maybe sounds are not what we think they are, depending on the timescale interpretations change.
