Ugh, I am so grossed out after reading this article, “Pedestrians Inhale Less Pollution than Passengers.” Out of various forms of ground transportation, walking exposes you to the least air pollution. You’d think being in this big metal enclosed box on wheels would keep air pollution away, but nope, you’re wrong. According to the article, you’ll inhale the most pollution via taxi ride. As if taxis weren’t already disgusting enough. In retrospect, it makes sense. I mean, your air conditioning is sucking up the air from the exhaust pipe of the car, or diesel truck, in front of you. I’m having difficulty breathing just thinking about this stuff.
