The New York Times created a visualization of air pollution that allows comparisons between local conditions and the worst air pollution in the world.

Nadja Popovich, Blacki Migliozzi, Karthik Patanjali, Anjali Singhvi, and Jon Huang are credited on this one-of-a-kind data visualization, which brings home the reality of air pollution.
Scroll through the article as floating particles make the point about air quality in cities around the world, and the air quality during events occurring with more frequency, like the Camp Fire in Paradise in 2018.
But even the Camp Fire can't compare to the reality in New Delhi, where air pollution reached "apocalyptic highs" last month. The causes and effects of air pollution are summarized thusly:
This fine pollution mainly comes from burning things: Coal in power plants, gasoline in cars, chemicals in industrial processes, or woody materials and whatever else ignites during wildfires.

And, when breathed in, they wreak havoc on human health.
