Animals Roam Freely In Italian Cities With Humans In Lockdown

Thanks to the absence of tourists and much-reduced traffic due to Italy’s quarantine measures to tackle the recent Coronavirus outbreak, pollution levels drop across many Italian cities and rarely seen animals are roaming the deserted streets.

The canals in Venice have become clear enough to see the return of fish, swans, cormorants and even dolphins. The lack of boats and cruise ships on the canals and in the harbor keeps water movements at a minimum, causing clay particles and other pollutants to settle on the ground. “Venice hasn’t seen clear canal water in a very long time,” Italian photographer Gianluca De Santis tweeted this week. “Dolphins showing up, too. Nature just hit the reset button on us.”

Curious dolphins approaching the piers are reported also in the port of Cagliari, one of the largest Italian seaports and one of the largest seaports in the Mediterranean Sea basin, with an annual traffic capacity of around 50 million tonnes of cargo and 1,000,000 containers.

As animals take advantage from limited human activity, also nature takes a breath. Images taken by the European Space Agency’s satellite Sentinel-5 show a significant drop in air pollution levels, especially the concentration of nitrogen compounds from burning fossil fuel, above the large industrial centers of Northern Italy, now in a lockdown since March 8.

The reduction of airborne particles is helped by favorable weather. Last week heavy rainfalls washed dust out of the air, and a light breeze dispersed the gaseous compounds.

As more and more countries adopt strict quarantine measures, reducing traffic and closing factories, the global emission of carbon-monoxide and similar pollutants dropped by 53% if compared to the emissions in March 2019.
