Before & After Pics Show How Much Cleaner Canadian Cities Are With Everyone At Home

Less driving means cleaner air.

Everyone being stuck at home has had at least one positive effect. Air pollution in Canada's cities has decreased due to all the necessary social distancing. Satellite images show just how significant the reduction has been.

Descartes Labs provided Narcity with images that show the levels of nitrogen dioxide above Toronto, Edmonton, Calgary and Vancouver. 

The pictures, taken by the European Space Agency's Sentinel-5P satellite, provide a look at the current average level of the air pollutant as compared to last year, per CBC News.

According to Health Canada, this particular compound is found in car exhaust and cigarette smoke.

Nitrogen dioxide can cause a number of respiratory problems. On top of coughing and wheezing, it can also weaken lung function over time and make cases of asthma worse.

In the provided images, it's clear to see how much of a decrease there's been in Canadian cities just by having people stay home and drive their cars less.

The drop in air pollution isn't exclusive to Canada. Data from the European Space Agency shows that major cities in Europe, including Paris, Madrid and Rome, have seen drops in their nitrogen dioxide concentrations.

Toronto

The Big Smoke is looking a little less smoky now that people aren't filling up the streets like they used to. Higher concentrations of pollution seem to be remaining closer to Hamilton, which is known for its manufacturing.

Edmonton

Alberta's capital city, along with its surrounding area, saw a reduction in overall air pollution. Unlike Toronto, the regions around Edmonton have remained mostly clear.

Calgary

The home of the famous Stampede has also seen a major drop in air pollutants since the start of Canada's social distancing measures.

Vancouver

Finally, Canada's West Coast has also seen a decline in its levels of nitrogen dioxide. It seems like staying home is helping to stop the spread of air pollution as much as anything else.
