Air pollution plummets amid COVID-19 outbreak

Meanwhile... pollution is dropping to record lows virtually everywhere in the world. These before/after shots show us a silver lining to the lockdown measures.

How has the lockdown affected pollution levels?

In Seoul, air pollution has visibly reduced since late January, when the authorities asked the 9 million inhabitants to limit their movements. The city, which also benefits from the drop in emissions of its neighbor China, has lowered its NO2 levels, a pollutant caused by road transport and industrial activity.

Italy is experiencing the same phenomenon. Here, lockdown measures were imposed in early March and have reduced NO2 levels by 40%. In Paris, road traffic has been almost nonexistent since the country’s lockdown on March 17. In Île-de-France, NO2 levels have dropped over 60%. However, fine particles from residential heating and agriculture are still very present in the air.

In New York, air quality is also starting to improve. NO2 emissions have decreased by more than 50% compared to usual levels. In Los Angeles, a city known for its traffic and dependency on cars, the streets are empty. On March 18 at 5:00 p.m, the usual rush hour, traffic was 71% faster than usual.

    I live in Los Angeles and I feel like those pictures of LA traffic are misleading. There are still tons of cars out. Dont take my comment out of context now, I am not saying that traffic is horrible, but its far from dead as depicted in these pictures.

    This mother nature who was warning us for years to take care of the planet and giving us signs that she wasn't happy with what we were doing. So we experienced earthquakes, cyclones, seasons out of whack, crops failing but still we wouldn't listen until finally she unleashed her fury which was this virus. Hence this is a wake up call and the most devastating one we have and will ever experience. Also note our very young are not as affected compared to the rest of the population. Of course it's just my thoughts and I don't care if you believe it or not it's mine.

    What a shocking parallel at a time where dozen of thousands of people are dying and millions suffering from the economic consequences of the lockdown.
