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.
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 improved 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, 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.
“If you come home to a cold house and you have to heat it, that’s going to more than offset the savings from not driving your vehicle to work, on average,” Christopher Jones, a climate policy expert at the University of California, Berkeley, told Scientific American.
“If you come home to a beautiful day like we have in California, and there was somebody home anyway, really we’re not using much more energy than if I were at work.”
Household carbon footprints could potentially rise, offsetting the lowering of global emissions as a result of isolation during the outbreak.
The new coronavirus was first identified in Hubei province, China, in December 2019 and spread rapidly. While the outbreak has begun to level off in China, it seems the virus has found a foothold in a number of countries around the world, and it continues to spread.
Confused about COVID-19? Here are some things you need to know:
Health officials say the risk is very low for Canadians, but they caution against travel to affected areas (a list can be found here). If you do travel to these places, they recommend you self-monitor to see whether you develop symptoms and if you do, to contact public health authorities.
Symptoms can include fever, cough and difficulty breathing – very similar to a cold or flu. Some people can develop a more severe illness. People most at risk of this include older adults and people with severe chronic medical conditions like heart, lung or kidney disease.
To prevent the virus from spreading, experts recommend frequent handwashing and coughing into your sleeve. And if you get sick, stay at home.
