Coronavirus lockdown eases pollution, Venice canal runs clear

The novel coronavirus is causing panic worldwide, but one thing may benefit from the social isolation: the environment.

The COVID-19 outbreak hit countries like Italy really hard, forcing country officials to intervene and ask citizens to go into lockdown.

As a result, people stayed indoors, business shuttered their windows, cars stayed parked and families hunkered down to protect themselves from getting sick.

The Venice canal, typically bogged down with tourists in gondolas and cruise ships, is now crystal clear, according to photos shared by Twitter user @FolinAlberto.

Cruise ships are typically seen sailing into the Venice lagoon and have caused harmful levels of pollution, Euro Weekly News writes. Without them, the water has had a chance to clear.

A typical March would see nearly 700,000 people arrive in Venice on cruise ships or otherwise, the South China Morning Post reports.

The decline in tourism has brought “back the lagoon waters of ancient times, those of the post-war period, when it was even still possible to bathe in the waters of the canals,” according to local newspaper La Nuova di Venezia e Mestre.

Air quality has also approved in Italy.

Though social isolation has been difficult, it’s had a massively positive effect on CO2 emissions, according to European Space Agency data analyzed by the Washington Post.

Between Jan. 1 and March 12, concentrations of nitrogen dioxide fell — produced by cars and power plants — immensely, especially over Italy, according to the ESA’s Sentinel-5P satellite.

“I guess this is mostly diesel cars out of the road,” said Emanuele Massetti, an expert on the economics of climate change at Georgia Tech University, according to the Washington Post.

“I expect pollution to drop even further as the particles in the atmosphere (concentration) get either dispersed or absorbed. In a few days, they will enjoy the cleanest air ever in northern Italy.”

Since Jan. 1, air quality in China has significantly improved, too, per pollution monitoring satellites from NASA and the European Space Agency.

As with Italy, social isolation and the lockdown of certain cities has seen a decrease in cars on the road, meaning noxious gas emitted by vehicles, power plants and industrial facilities have come to a near complete halt.

Scientific American notes that events like the 2008 recession caused similar dips in global carbon emissions. On the flip side of things, the publication notes that more social isolation means people are likely using more energy in their homes — not a good thing.

It all depends on geography and family lifestyle.
