Many elements of these developmental tales seem to be distorted or misleading as discussed by this National Geographic Report. Swans and other seabirds are frequent visitors to the Burano canals, an island in Venice’s harbor. Similar to dolphins, marine wildlife is also known to reach the harbor. And, even if not unlikely, there is no actual evidence to support the recent reports that they were even seen in the canals.
Owing to Italy’s quarantine measures against a recent Coronavirus outbreak, the absence of visitors and the much-decreasing traffic decrease in many of Italy’s cities and rare animals are on the empty streets.
The Venice canals are clear enough to see fish, swans, cormorants and even dolphins returning to the country. The lack of canal and harbor-based vessels or cruise ships minimizes water movement and allows particles of clay and other contaminants to settle on the shore. “For a very long time, Venice has not seen clear water in the canal,” Gianluca De Santis Italian photographer tweeted. “Dolphins are also emerging. The reset button on us is just reached by chance.”
In the harbor, one of the largest seaports of the Mediterranean, Cagliari is also a port with annual traffic of around 50 million tons of freight and 1,000,000 containers, which is often regarded as a mysterious dolphin entering the piers.
In Rome, residents saw that ducks rest in the famous Trevi Brunnen without hundreds of tourists tossing coins in the water.
Wild boars wander the streets of Sassari, Sardinia’s second-largest city with 127,525 inhabitants.
When species benefit from restricted human intervention, nature often respires. Images taken with the satellite Sentinel-5 by the European Space Agency show a significant reduction of air pollution concentration over the large industrial centers of Northern Italy, which are now locked since 8 March, particularly the concentration of Nitrogen compounds from burning fossil fuels.
The atmosphere is good for growing airborne particles. Heavy rainfall washed out air dust last week, and gaseous compounds were spread by a mild brise.
With more and greater countries adopting stringent quarantine steps, restricting transport and closing factories, global carbon monoxide emissions, and related contaminants have dropped by 53% compared with March 2019 levels.
