Coronavirus Shutdowns Causing Huge Drops in Traffic, Air Pollution
The novel coronavirus that has caused a global pandemic is also having an enormous impact on the environment, according to new satellite data. As governments around the world have restricted people from moving, industry, air travel and vehicular traffic have grinded to a halt, causing pollution levels to plummet, according to The New York Times.
"This is the first time I have seen such a dramatic drop-off over such a wide area for a specific event," says Fei Liu, an air quality researcher at NASA's Goddard Space Flight Center, as CNN reported. "I am not surprised because many cities nationwide have taken measures to minimize the spread of the virus."
While President Trump does not enjoy watching the U.S. economy slow down and the markets lose value, the coronavirus is helping his erroneous assertion that the U.S. has the cleanest air in the world.
Areas that have been COVID-19 hotspots, like China and Italy, have already seen huge reductions in air pollution. Now the same trend is happening in major U.S. cities like Los Angeles, Seattle, New York, Chicago and Atlanta where rush hour congestion has vanished as trucks and cars are no longer choking the streets, according to The New York Times.
"Air pollution levels as observed by satellite are showing drastic improvements in many areas that have been undergoing restrictive quarantines due to COVID-19," Peter DeCarlo, an associate professor of environmental health engineering at Johns Hopkins University, told Newsweek.
"But it's [also] very clear that airline passenger numbers are way down, as many countries introduce travel bans and meetings/conferences/work-related travel is canceled. Industrial activity is also reduced, but not necessarily to the extent of traffic. For example, power plants still need to run to produce electricity, water treatment plants still need to continue to treat water, etcetera," he said.
Satellite imagery taken over the U.S. in the first three weeks of March shows less nitrogen dioxide over the country than the same period last year, according to data from the European Space Agency, as CNN reported.
Nitrogen dioxide levels are driven by burning fuels, as well as emissions of cars, trucks, buses, power plants and off-road equipment, according to CNN.
The New York Times noted that freeway traffic in Los Angeles, which is usually at a standstill during rush hour, was moving at a brisk 71 miles per hour.
"There's basically no rush hour anymore, or at least not what we would recognize as a rush hour," said Trevor Reed, a transportation analyst at INRIX, a company that analyzes traffic data from vehicle and phone navigation systems, to The New York Times.
A similar trend is happening in the Bay Area, where crossings of the heavily trafficked Bay Bridge that connects San Francisco to Oakland have dropped by 40 percent, according to the California Department of Transportation, as The New York Times reported.
In New York City, researchers from Columbia University noticed remarkable dips in carbon levels over New York City, which declined more than 50 percent below normal levels. We've never seen anything like the drop we saw starting last Friday," said Roisin Commane, an assistant professor at Columbia who conducts the air-monitoring work, referring to March 13, The New York Times reported.
"We often see dips during weekends or over holidays, but this is completely different."
The drop in pollution levels is mirrored around the world, wherever people are staying home to try to stop the spread of the novel coronavirus. In China, nitrogen dioxide levels dropped 35 percent, and up to 60 percent in some cities. Similarly, reductions of up to 40 percent were seen in Milan, according to Newsweek.
Marshall Burke, an assistant professor at Stanford's Department of Earth System Science, said the improved air quality might save between 50,000 and 75,000 people from premature death, according to CNN.

As protests are taking place across our nation in response to the killing of George Floyd, we want to acknowledge the importance of this protest and the Black Lives Matter movement. Over the years, we've aimed to be sensitive and prioritize stories that highlight the intersection between racial and environmental injustice. From our years of covering the environment, we know that too often marginalized communities around the world are disproportionately affected by environmental crises.

With more than 1.7 million confirmed cases of COVID-19 in the United States and more than 100,000 deaths from the virus, physicians face unprecedented challenges in their efforts to keep Americans safe.
They also encounter what some call an "infodemic," an outbreak of misinformation that's making it more difficult to treat patients.
When Leaders and Doctors Spread Misinformation<p>When people in charge of towns, cities, states, and countries spread misinformation, the potential for belief in misinformation to result in policies can have harmful effects.</p><p><a href="https://www.northwell.edu/find-care/find-a-doctor?q=Bruce+E.+Hirsch%2C+MD&insurance=&location=&query_type=provider&physician_partners=false&default_view=list&gender=&language=&sort=relevancy" target="_blank">Dr. Bruce E. Hirsch</a>, attending physician and assistant professor in the infectious disease division of Northwell Health in Manhasset, New York, says an example of this is when President Trump informed the public he was taking hydroxychloroquine as a preventive measure.</p><p>"To approach this enormous challenge, we need some intellectual honesty and clarity, and to disregard expertise and to make decisions and model decisions based on hunches is inviting us to handle challenges on the basis of rumor and uninformed opinion. The magnitude of that error is epic," Hirsch told Healthline.</p><p>Stukus agrees, noting that the harm of this proclamation is documented.</p><p>"Early on when the president touted the benefits of hydroxychloroquine and azithromycin, people started to hoard this medicine, and state boards had to shut it down because they were getting so many prescriptions for this unproven therapy that it was not available for those who truly needed it, such as those who have lupus and autoimmune conditions," Stukus said.</p><p>He adds that calls to poison control centers increased after the president suggested using disinfectant to prevent contracting the new coronavirus.</p>
Listen to Science, Even When it Changes<p>When recommendations change or evidence flip-flops, skepticism may arise. However, Stukus says change is the beauty of science.</p><p>"That shows us that we can evolve, and if the evidence shows that our prior thoughts were incorrect, we need to be able to change our recommendations and advice based upon the best quality of evidence at the time," he said.</p><p>Pierre agrees.</p><p>"Science is an iterative process, whereby we arrive at facts and truth through repeated and controlled observations. That means that it's inherently self-correcting as we revise conclusions based on ongoing research. Scientific facts aren't immutable dogma chiseled on a tablet. They change based on the best available evidence we have at a given point in time," he said.</p><p>Because research of COVID-19 has only been underway for 6 months, information is evolving rapidly, and new information may contradict old.</p><p>"There's still much we don't know about exactly how [COVID-19] spreads, what effects it has on the body, or how to best treat it. That means that the best available evidence is preliminary, but that doesn't mean that we should ignore it or turn to other sources of information or opinion as if they're just as valid," Pierre said.</p><p>He explains that conspiracy theories based on mistrust lead to vulnerability to misinformation.</p><p>If people mistrust science because it sometimes "changes its mind," Pierre said, "that shouldn't be used to embrace other opinions based on no evidence at all, which are typically selected based on confirmation bias: what we want to believe rather than what the objective evidence supports."</p>
Where to Find the Best Information<p>Stukus says to start with the <a href="https://www.cdc.gov/coronavirus/2019-nCoV/index.html" target="_blank">CDC</a> and <a href="https://www.nih.gov/health-information/coronavirus" target="_blank">NIH</a>. Then check with your local health officials, because COVID-19 guidelines may vary depending on where you live.</p><p>If you can't find information you need or have questions specifically related to you, call your primary care doctor.</p><p>"Your personal doctor should always be a resource for individual specific questions because they know best how to apply all the nuances retaining to your health, and how to incorporate all the other general [COVID-19] recommendations," Stukus said.</p><p><a href="https://www.eehealth.org/find-a-doctor/b/boyd-laura-b/" target="_blank">Dr. Laura Boyd</a>, primary care physician at Edward-Elmhurst Health Center in Elmhurst, Illinois, says her clinic receives a lot of calls about COVID-19.</p><p>"Most doctors' offices are receiving calls and answering questions, and doing phone or video visits to help clarify and/or order testing over the phone based on patients' symptoms. It is always best to call your doctor's office first instead of worrying about symptoms and waiting too long to seek treatment," she told Healthline.</p><p>If your primary care doctor has limited testing, she suggests looking on your state's public health website for available testing sites.</p><p>With a lot of unknowns related to this virus and disease, Boyd says many patients are feeling overwhelmed and anxious for a treatment.</p><p>"Unfortunately, there is no specific medication recommended for COVID for outpatient. There are a lot of ongoing studies with various drugs going on within the hospital setting. Patients should always contact their doctors about their specific symptoms as they can treat the symptoms that go along with COVID, but there is no cure," Boyd said.</p><p>While we wait for treatment and a vaccine, Hirsch, who treats patients hospitalized for COVID-19 complications on a daily basis, says everyone can do their part by washing hands, wearing a mask, and staying 6 feet apart.</p><p>"As an infectious disease doctor working in the hospital, I see the damage of the pandemic and the worst cases of what's happening. We are trying to get the best possible outcome and confronting this overwhelming biologic reality of this terrible epidemic the best we can," Hirsch said.</p><p>Everyone at home can help in the fight too, he adds.</p><p>"Follow information that is science- and evidence-based, and avoid that which is not," he said.</p>
