Coronavirus has found a friend! China’s air quality dramatically improves.

The country-wide ban on public gatherings & industrial production has reduced air pollution dramatically.

The coronavirus (COVID-19) has shocked the world, and it will continue to do so for the foreseeable future. The flu-like disease infected close to 90,000 people around the world since it was first discovered in late December. While China is reporting fewer cases, several other hot zones emerged in the past few weeks, including Italy, Iran, and South Korea, where the number of registered cases grow at somewhat alarming rates.

While over 45,000 patients have recovered so far, the coronavirus killed over 3,000 patients, and impacted everyday life and the world economy. Production of goods in China has been halted, as entire areas were quarantined to put a stop to the virus’ spread. Several trade shows around the world have been canceled, including MWC and the Geneva Auto Show, and even the upcoming Summer Olympic Games are at risk of being canceled. One way to stop the outbreak, aside from increasing awareness and encouraging better personal hygiene, is to limit travel and gatherings of people. It turns out that keeping people at home for a prolonged quarantine, best observed in places like in China, has had an unexpected side-effect on the quality of life in the region.

You know what people don’t do when they’re forced to stay indoors for a long period of time? They don’t get in their cars to drive places, and it turns out that two months of reduced travel was enough for China’s air to become clear of toxins. It’s a sad silver lining, but new satellite imagery from NASA and the European Space Agency showed “significant decreases in nitrogen dioxide (NO2) over China.”

The change is “at least partly related to the economic slowdown following the outbreak of coronavirus,” NASA explained in a press release, showing the following maps to prove its findings.

This image shows a reduction in pollutants for most of February, compared to the first three weeks of January:

Even more interesting is the comparison to last year’s data for the same period. That’s because the Chinese New Year vacation lasted longer, with many people prevented from traveling during the period:

“This is the first time I have seen such a dramatic drop-off over such a wide area for a specific event,” air quality researcher at NASA’s Goddard Space Flight Center Fei Liu. The researcher says a similar drop in NO2 occurred over several countries during the economic recession that began in 2008, but the decrease was more gradual. “This year, the reduction rate is more significant than in past years, and it has lasted longer,” she said. “I am not surprised because many cities nationwide have taken measures to minimize spread of the virus.”

Once the coronavirus threat passes, however, pollution is likely to go up in China and other affected areas.

Tree Air Purity – Why Tree-Hugging is Good for your Health

Ancient health wisdom is rarely wrong. Turns out tree-hugging is great for your health & wellbeing.

Forest bathing is the latest health trend, but what exactly is it?

Translated from the Japanese term “shinrin-yoku,” forest bathing also is known as forest therapy. It’s somewhat like hiking through the forest. It’s also like meditating among the trees. Yet it’s not exactly either.

Diana Beresford-Kroeger, the first to write about tree aerosols, says “tree compounds are released like rockets into the air.”
Beresford-Kroeger spoke last year at the Canadian Ecology Centre’s Earth Day book talks. She is a world-recognized author, medical biochemist and botanist.

Beresford-Kroeger has a unique combination of western scientific knowledge and the traditional concepts of the ancient world. She was one of the first to conceptualize what forest therapy really is.

“Tree air is loaded with antibiotics, anti-inflammatories, antiseptics, antivirals and analgesics,” she says.

Trees and other plants produce hundreds to thousands of volatile organic compounds (VOCs). These carbon-based chemicals easily evaporate from a liquid or solid into air at much lower temperatures than most chemicals, Beresford-Kroeger explains.

“For example, your nose is sensing VOCs when you smell pine trees.”

She gives us the reasons why trees are so beneficial for our health.

“Trees produce their own self-defence mechanisms,” says Beresford-Kroeger. “Trees secrete these compounds to protect themselves from insects and microbes. By simply being close to trees, we breathe in these antimicrobials. A growing body of research has shown that living close to trees has beneficial effects on mental health, as well as well-being, mood, cognition and lifespan.”

These airborne compounds increase immune system regulators, while decreasing respiratory rates, stress levels, blood pressure and stress (adrenaline and cortisol).

Beresford-Kroeger has an ambitious “bioplan” encouraging ordinary people to develop a new relationship with nature, to join together to replant the global forest and be “with nature.”

Her books include The Sweetness of a Simple Life, The Global Forest, Arboretum Borealis, Arboretum America and A Garden for Life.

Beresford-Kroeger was elected as a fellow of the Royal Geographical Society in 2011. More recently, in 2016, the society named her one of 25 women explorers of Canada.

“Like the brain, trees are an enigma machine,” says Beresford-Kroeger. “Nobody knows how they really work. Trees have more DNA than a human child. They communicate in two ways: One, by silent infrasound into the emotions; the other, in a chemical communication with the atmosphere. The drum of the tree beats a message to us all.”

Beresford-Kroeger encourages walks in all seasons. But a forest therapy guide is not a therapist, she emphasizes.

“The forest itself is the therapist,” she says. “The forest does all the work. My words simply open the door to the forest to help connect the forest with the person.”

If needed, Beresford-Kroeger says you can be guided by certified professionals and Google will find programs for you.

“The guide’s role isn’t to explain the flora and fauna. Rather, the guide facilitates the contemplative experience, offering participants invitations to interact with the forest in a meaningful and healing way.

“How many of us really slow down and feel the different textures in the forest?” she asks.

Where are those trees with aerosols and where can we get a dose this winter?

Guylaine Thauvette, Nipissing forest management forester with the Ministry of Natural Resources and Forestry North Bay District, suggests a ‘Sunday’ drive to Boulter Township where there are some of the area’s most expansive, mature red pine plantations dating back to the 1940s.

Best access is from Rutherglen on Hwy. 17 E. Take the Rutherglen Line to Development Road, turn right on Farmer’s Line, left on Laplante Road, left on Guay Road and right on what will turn into what is known locally as ‘Grand Desert’ Road.

It is here you will see an expansive plantation, looking east. These roads are former colonization roads, with many farmsteads, active and abandoned.
