Since the lock down of Wuhan, it has been drastically seen that air pollution has greatly decreased in the outskirts of the city. It appears that something similar is also beginning to happen in Venice, in Italy, which has also locked down their country. The European Space Agency (ESA) released a time-lapse video taken from space, which shows how wondrously the air pollution has diminished.
“Due to the reduction of activity at factories and on highways these changes have occurred worldwide” said Claus Zehner, who manages the Copernicus Sentinel-5P, the satellite which took the photos over the Po Valley region. “Although there could be slight variations in the data due to cloud cover and changing weather, we are very confident that the reduction in emissions that we can see coincides with the shutdown in Italy causing less traffic and industrial activities,” Zehner said.
The typically murky waters in the Venice canals have cleared up as everyone has been locked inside. As traffic in the waterways has come to a halt the canals in Venice have also been super clear. Now it is amazingly “Clear Venice”. Nature reclaims its spaces. Less traffic, less discharge.” It is further explained to others that the boats were not kicking up sediment as they would during a normal season.
“As regards the clarity, the absence of traffic that moves the sediments is certainly the cause of this miracle from the tropical sea. The reduced discharges and the water exchange of the tides instead benefit the quality of the waters,” the researcher explained.
